This is usually + known as the "alpha-test" phase among developers. If a feature is + currently in alpha-test, then the developers usually discourage + uninformed widespread use of this feature by the general public to + avoid "Why doesn't this work?" type mail messages. However, active + testing and use of these systems is welcomed. Just be aware that it + may not meet the normal level of reliability or it may fail to work + in some special cases. Detailed bug reports from people familiar + with the kernel internals are usually welcomed by the developers + (before submitting bug reports, please read the documents + <file:README>, <file:MAINTAINERS>, <file:REPORTING-BUGS>, + <file:Documentation/BUG-HUNTING>, and + <file:Documentation/oops-tracing.txt> in the kernel source). + + This option will also make obsoleted drivers available. These are + drivers that have been replaced by something else, and/or are + scheduled to be removed in a future kernel release. + + Unless you intend to help test and develop a feature or driver that + falls into this category, or you have a situation that requires + using these features, you should probably say N here, which will + cause the configurator to present you with fewer choices. If + you say Y here, you will be offered the choice of using features or + drivers that are currently considered to be in the alpha-test phase. + +Prompt for drivers for obsolete features and hardware +CONFIG_OBSOLETE + Obsolete drivers have usually been replaced by more recent software + that can talk to the same hardware. Obsolete hardware is things + like MGA monitors that you are very unlikely to see on today's + systems. + +Prompt for advanced kernel configuration options +CONFIG_ADVANCED_OPTIONS + This option will enable prompting for a variety of advanced kernel + configuration options. These options can cause the kernel to not + work if they are set incorrectly, but can be used to optimize certain + aspects of kernel memory management. + + Unless you know what you are doing you *should not* enable this option. + +Symmetric Multi-Processing support +CONFIG_SMP + This enables support for systems with more than one CPU. If you have + a system with only one CPU, like most personal computers, say N. If + you have a system with more than one CPU, say Y. + + If you say N here, the kernel will run on single and multiprocessor + machines, but will use only one CPU of a multiprocessor machine. If + you say Y here, the kernel will run on many, but not all, + single machines. On a singleprocessor machine, the kernel + will run faster if you say N here. + + Note that if you say Y here and choose architecture "586" or + "Pentium" under "Processor family", the kernel will not work on 486 + architectures. Similarly, multiprocessor kernels for the "PPro" + architecture may not work on all Pentium based boards. + + People using multiprocessor machines who say Y here should also say + Y to "Enhanced Real Time Clock Support", below. The "Advanced Power + Management" code will be disabled if you say Y here. + + See also the <file:Documentation/smp.tex>, + <file:Documentation/smp.txt>, <file:Documentation/i386/IO-APIC.txt>, + <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available at + <http://www.tldp.org/docs.html#howto>. + + If you don't know what to do here, say N. + +Maximum number of CPUs +CONFIG_NR_CPUS + This allows you to specify the maximum number of CPUs which this + kernel will support. The maximum supported value is 32 and the + mimimum value which makes sense is 2. + + This is purely to save memory - each supported CPU adds + approximately eight kilobytes to the kernel image. + +Intel or compatible 80x86 processor +CONFIG_X86 + This is Linux's home port. Linux was originally native to the Intel + 386, and runs on all the later x86 processors including the Intel + 486, 586, Pentiums, and various instruction-set-compatible chips by + AMD, Cyrix, and others. + +Alpha processor +CONFIG_ALPHA + The Alpha is a 64-bit general-purpose processor designed and + marketed by the Digital Equipment Corporation of blessed memory, now + Compaq. Alpha Linux dates from 1995-1996 and was the first non-x86 + port. The Alpha Linux project has a home page at + <http://www.alphalinux.org/>. + +32-bit Sun Sparc +CONFIG_SPARC32 + SPARC is a family of RISC microprocessors designed and marketed by + Sun Microsystems, incorporated. They are very widely found in Sun + workstations and clones. This port covers the original 32-bit SPARC; + it is old and stable and usually considered one of the "big three" + along with the Intel and Alpha ports. The UltraLinux project + maintains both the SPARC32 and SPARC64 ports; its web page is + available at <http://www.ultralinux.org/>. + +64-bit Sun Sparc +CONFIG_SPARC64 + SPARC is a family of RISC microprocessors designed and marketed by + Sun Microsystems, incorporated. This port covers the newer 64-bit + UltraSPARC. The UltraLinux project maintains both the SPARC32 and + SPARC64 ports; its web page is available at + <http://www.ultralinux.org/>. + +Power PC processor +CONFIG_PPC + The PowerPC is a very capable 32-bit RISC processor from Motorola, + the successor to their 68000 and 88000 series. It powers recent + Macintoshes and also a widely-used series of single-board computers + from Motorola. The Linux PowerPC port has a home page at + <http://penguinppc.org/>. + +Motorola 68K processors +CONFIG_M68K + The Motorola 68K microprocessors are now obsolete, having been + superseded by the PowerPC line also from Motorola. But they powered + the first wave of workstation hardware in the 1980s, including Sun + workstations; they were also the basis of the original Amiga and + later Atari personal computers. A lot of this hardware is still + around. The m68k project has a home page at + <http://www.linux-m68k.org/>. + +ARM processors +CONFIG_ARM + The ARM series is a line of low-power-consumption RISC chip designs + licensed by ARM ltd and targeted at embedded applications and + handhelds such as the Compaq IPAQ. ARM-based PCs are no longer + manufactured, but legacy ARM-based PC hardware remains popular in + Europe. There is an ARM Linux project with a web page at + <http://www.arm.linux.org.uk/>. + +SuperH processors +CONFIG_SUPERH + The SuperH is a RISC processor targeted for use in embedded systems + and consumer electronics; it was also used in the Sega Dreamcast + gaming console. The SuperH port has a home page at + <http://www.sh-linux.org/>. + +IA64 processors, including Intel Itanium +CONFIG_IA64 + The Itanium is Intel's 64-bit successor to the 32-bit X86 line. As + of early 2001 it is not yet in widespread production use. The Linux + IA-64 project has a home page at <http://www.linuxia64.org/>. + +HP PA-RISC processor +CONFIG_PARISC + The PA-RISC microprocessor is a RISC chip designed by + Hewlett-Packard and used in their line of workstations. The PA-RISC + Linux project has a home page at <www.parisc-linux.org>. + +IBM System/390 +CONFIG_S390 + Linux now runs on the venerable System/390 mainframe from IBM, in a + guest partition under VM. In fact, over 40,000 simultaneous Linux + images have been run on a single mainframe! The S390 Linux project + has a home page at <http://linux.s390.org/>. + +Axis Communications ETRAX 100LX embedded network CPU +CONFIG_CRIS + Linux has been ported to run on the Axis Communications ETRAX 100LX + CPU and the single-board computers built around it, targeted for + network and embedded applications. For more information see the + Axis Communication site, <http://developer.axis.com/>. + +Unsynced TSC support +CONFIG_X86_TSC_DISABLE + This option is used for getting Linux to run on a NUMA multi-node + boxes, laptops and other systems suffering from unsynced TSCs or + TSC drift, which can cause gettimeofday to return non-monotonic values. + Choosing this option will disable the CONFIG_X86_TSC optimization, + and allows you to then specify "notsc" as a boot option regardless of + which processor you have compiled for. + + NOTE: If your system hangs when init should run, you are probably + using a i686 compiled glibc which reads the TSC without checking for + availability. Boot without "notsc" and install a i386 compiled glibc + to solve the problem. + + If unsure, say N. + +Multiquad support for NUMAQ systems +CONFIG_X86_NUMAQ + This option is used for getting Linux to run on a (IBM/Sequent) NUMA + multiquad box. This changes the way that processors are bootstrapped, + and uses Clustered Logical APIC addressing mode instead of Flat Logical. + You will need a new lynxer.elf file to flash your firmware with - send + email to Martin.Bligh@us.ibm.com + +Support for IBM Summit (EXA) systems +CONFIG_X86_SUMMIT + This option is needed for IBM systems that use the Summit/EXA chipset. + (EXA: Extendable Xseries Architecture)In particular, it is needed for + the x440 (even for the 4-CPU model). + + If you don't have this computer, you may safely say N. + +IO-APIC support on uniprocessors +CONFIG_X86_UP_IOAPIC + An IO-APIC (I/O Advanced Programmable Interrupt Controller) is an + SMP-capable replacement for PC-style interrupt controllers. Most + SMP systems and a small number of uniprocessor systems have one. + If you have a single-CPU system with an IO-APIC, you can say Y here + to use it. If you say Y here even though your machine doesn't have + an IO-APIC, then the kernel will still run with no slowdown at all. + + If you have a system with several CPUs, you do not need to say Y + here: the IO-APIC will be used automatically. + +Local APIC Support on Uniprocessors +CONFIG_X86_UP_APIC + A local APIC (Advanced Programmable Interrupt Controller) is an + integrated interrupt controller in the CPU. If you have a single-CPU + system which has a processor with a local APIC, you can say Y here to + enable and use it. If you say Y here even though your machine doesn't + have a local APIC, then the kernel will still run with no slowdown at + all. The local APIC supports CPU-generated self-interrupts (timer, + performance counters), and the NMI watchdog which detects hard lockups. + + If you have a system with several CPUs, you do not need to say Y + here: the local APIC will be used automatically. + +Kernel math emulation +CONFIG_MATH_EMULATION + Linux can emulate a math coprocessor (used for floating point + operations) if you don't have one. 486DX and Pentium processors have + a math coprocessor built in, 486SX and 386 do not, unless you added + a 487DX or 387, respectively. (The messages during boot time can + give you some hints here ["man dmesg"].) Everyone needs either a + coprocessor or this emulation. + + If you don't have a math coprocessor, you need to say Y here; if you + say Y here even though you have a coprocessor, the coprocessor will + be used nevertheless. (This behaviour can be changed with the kernel + command line option "no387", which comes handy if your coprocessor + is broken. Try "man bootparam" or see the documentation of your boot + loader (lilo or loadlin) about how to pass options to the kernel at + boot time.) This means that it is a good idea to say Y here if you + intend to use this kernel on different machines. + + More information about the internals of the Linux math coprocessor + emulation can be found in <file:arch/i386/math-emu/README>. + + If you are not sure, say Y; apart from resulting in a 66 KB bigger + kernel, it won't hurt. + +Timer and CPU usage LEDs +CONFIG_LEDS + If you say Y here, the LEDs on your machine will be used + to provide useful information about your current system status. + + If you are compiling a kernel for a NetWinder or EBSA-285, you will + be able to select which LEDs are active using the options below. If + you are compiling a kernel for the EBSA-110 or the LART however, the + red LED will simply flash regularly to indicate that the system is + still functional. It is safe to say Y here if you have a CATS + system, but the driver will do nothing. + +Timer LED +CONFIG_LEDS_TIMER + If you say Y here, one of the system LEDs (the green one on the + NetWinder, the amber one on the EBSA285, or the red one on the LART) + will flash regularly to indicate that the system is still + operational. This is mainly useful to kernel hackers who are + debugging unstable kernels. + + The LART uses the same LED for both Timer LED and CPU usage LED + functions. You may choose to use both, but the Timer LED function + will overrule the CPU usage LED. + +CPU usage LED +CONFIG_LEDS_CPU + If you say Y here, the red LED will be used to give a good real + time indication of CPU usage, by lighting whenever the idle task + is not currently executing. + + The LART uses the same LED for both Timer LED and CPU usage LED + functions. You may choose to use both, but the Timer LED function + will overrule the CPU usage LED. + +Kernel FP software completion +CONFIG_MATHEMU + This option is required for IEEE compliant floating point arithmetic + on the Alpha. The only time you would ever not say Y is to say M in + order to debug the code. Say Y unless you know what you are doing. + +# Choice: himem +High Memory support +CONFIG_NOHIGHMEM + Linux can use up to 64 Gigabytes of physical memory on x86 systems. + However, the address space of 32-bit x86 processors is only 4 + Gigabytes large. That means that, if you have a large amount of + physical memory, not all of it can be "permanently mapped" by the + kernel. The physical memory that's not permanently mapped is called + "high memory". + + If you are compiling a kernel which will never run on a machine with + more than 960 megabytes of total physical RAM, answer "off" here (default + choice and suitable for most users). This will result in a "3GB/1GB" + split: 3GB are mapped so that each process sees a 3GB virtual memory + space and the remaining part of the 4GB virtual memory space is used + by the kernel to permanently map as much physical memory as + possible. + + If the machine has between 1 and 4 Gigabytes physical RAM, then + answer "4GB" here. + + If more than 4 Gigabytes is used then answer "64GB" here. This + selection turns Intel PAE (Physical Address Extension) mode on. + PAE implements 3-level paging on IA32 processors. PAE is fully + supported by Linux, PAE mode is implemented on all recent Intel + processors (Pentium Pro and better). NOTE: If you say "64GB" here, + then the kernel will not boot on CPUs that don't support PAE! + + The actual amount of total physical memory will either be auto + detected or can be forced by using a kernel command line option such + as "mem=256M". (Try "man bootparam" or see the documentation of your + boot loader (grub, lilo or loadlin) about how to pass options to the + kernel at boot time.) + + If unsure, say "off". + +4GB +CONFIG_HIGHMEM4G + Select this if you have a 32-bit processor and between 1 and 4 + gigabytes of physical RAM. + +64GB +CONFIG_HIGHMEM64G + Select this if you have a 32-bit processor and more than 4 + gigabytes of physical RAM. + +HIGHMEM I/O support +CONFIG_HIGHIO + If you want to be able to do I/O to high memory pages, say Y. + Otherwise low memory pages are used as bounce buffers causing a + degrade in performance. + +OOM killer support +CONFIG_OOM_KILLER + This option selects the kernel behaviour during total out of memory + condition. + + The default behaviour is to, as soon as no freeable memory and no swap + space are available, kill the task which tries to allocate memory. + The default behaviour is very reliable. + + If you select this option, as soon as no freeable memory is available, + the kernel will try to select the "best" task to be killed. + + If unsure, say N. + +Normal floppy disk support +CONFIG_BLK_DEV_FD + If you want to use the floppy disk drive(s) of your PC under Linux, + say Y. Information about this driver, especially important for IBM + Thinkpad users, is contained in <file:Documentation/floppy.txt>. + That file also contains the location of the Floppy driver FAQ as + well as location of the fdutils package used to configure additional + parameters of the driver at run time. + + This driver is also available as a module ( = code which can be + inserted in and removed from the running kernel whenever you want). + The module will be called floppy.o. If you want to compile it as a + module, say M here and read <file:Documentation/modules.txt>. + +iSeries Virtual I/O Disk Support +CONFIG_VIODASD + If you are running on an iSeries system and you want to use + virtual disks created and managed by OS/400, say Y. + +iSeries Virtual I/O Disk IDE Emulation +CONFIG_VIODASD_IDE + This causes the iSeries virtual disks to look like IDE disks. + If you have programs or utilities that only support certain + kinds of disks, this option will cause iSeries virtual disks + to pretend to be IDE disks, which may satisfy the program. + +Support for PowerMac floppy +CONFIG_MAC_FLOPPY + If you have a SWIM-3 (Super Woz Integrated Machine 3; from Apple) + floppy controller, say Y here. Most commonly found in PowerMacs. + +RAM disk support +CONFIG_BLK_DEV_RAM + Saying Y here will allow you to use a portion of your RAM memory as + a block device, so that you can make file systems on it, read and + write to it and do all the other things that you can do with normal + block devices (such as hard drives). It is usually used to load and + store a copy of a minimal root file system off of a floppy into RAM + during the initial install of Linux. + + Note that the kernel command line option "ramdisk=XX" is now + obsolete. For details, read <file:Documentation/ramdisk.txt>. + + If you want to compile this as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M and read <file:Documentation/modules.txt>. The module will be + called rd.o. + + Most normal users won't need the RAM disk functionality, and can + thus say N here. + +Default RAM disk size +CONFIG_BLK_DEV_RAM_SIZE + The default value is 4096. Only change this if you know what are + you doing. If you are using IBM S/390, then set this to 8192. + +Initial RAM disk (initrd) support +CONFIG_BLK_DEV_INITRD + The initial RAM disk is a RAM disk that is loaded by the boot loader + (loadlin or lilo) and that is mounted as root before the normal boot + procedure. It is typically used to load modules needed to mount the + "real" root file system, etc. See <file:Documentation/initrd.txt> + for details. + +Embed root filesystem ramdisk into the kernel +CONFIG_EMBEDDED_RAMDISK + Select this option if you want to build the ramdisk image into the + the final kernel binary. + +Filename of gziped ramdisk image +CONFIG_EMBEDDED_RAMDISK_IMAGE + This is the filename of the ramdisk image to be built into the + kernel. Relative pathnames are relative to arch/mips/ramdisk/. + The ramdisk image is not part of the kernel distribution; you must + provide one yourself. + +Loopback device support +CONFIG_BLK_DEV_LOOP + Saying Y here will allow you to use a regular file as a block + device; you can then create a file system on that block device and + mount it just as you would mount other block devices such as hard + drive partitions, CD-ROM drives or floppy drives. The loop devices + are block special device files with major number 7 and typically + called /dev/loop0, /dev/loop1 etc. + + This is useful if you want to check an ISO 9660 file system before + burning the CD, or if you want to use floppy images without first + writing them to floppy. Furthermore, some Linux distributions avoid + the need for a dedicated Linux partition by keeping their complete + root file system inside a DOS FAT file using this loop device + driver. + + The loop device driver can also be used to "hide" a file system in a + disk partition, floppy, or regular file, either using encryption + (scrambling the data) or steganography (hiding the data in the low + bits of, say, a sound file). This is also safe if the file resides + on a remote file server. If you want to do this, you will first have + to acquire and install a kernel patch from + <ftp://ftp.kerneli.org/pub/kerneli/>, and then you need to + say Y to this option. + + Note that alternative ways to use encrypted file systems are + provided by the cfs package, which can be gotten from + <ftp://ftp.kerneli.org/pub/kerneli/net-source/>, and the newer tcfs + package, available at <http://tcfs.dia.unisa.it/>. You do not need + to say Y here if you want to use one of these. However, using cfs + requires saying Y to "NFS file system support" below while using + tcfs requires applying a kernel patch. An alternative steganography + solution is provided by StegFS, also available from + <ftp://ftp.kerneli.org/pub/kerneli/net-source/>. + + To use the loop device, you need the losetup utility and a recent + version of the mount program, both contained in the util-linux + package. The location and current version number of util-linux is + contained in the file <file:Documentation/Changes>. + + Note that this loop device has nothing to do with the loopback + device used for network connections from the machine to itself. + + If you want to compile this driver as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read <file:Documentation/modules.txt>. The module + will be called loop.o. + + Most users will answer N here. + +Micro Memory MM5415 Battery Backed RAM support (EXPERIMENTAL) +CONFIG_BLK_DEV_UMEM + Saying Y here will include support for the MM5415 family of + battery backed (Non-volatile) RAM cards. + <http://www.umem.com/> + + The cards appear as block devices that can be partitioned into + as many as 15 partitions. + + If you want to compile this driver as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read Documentation/modules.txt. The module will be + called umem.o. + + The umem driver has been allocated block major number 116. + See Documentation/devices.txt for recommended device naming. + +Network block device support +CONFIG_BLK_DEV_NBD + Saying Y here will allow your computer to be a client for network + block devices, i.e. it will be able to use block devices exported by + servers (mount file systems on them etc.). Communication between + client and server works over TCP/IP networking, but to the client + program this is hidden: it looks like a regular local file access to + a block device special file such as /dev/nd0. + + Network block devices also allows you to run a block-device in + userland (making server and client physically the same computer, + communicating using the loopback network device). + + Read <file:Documentation/nbd.txt> for more information, especially + about where to find the server code, which runs in user space and + does not need special kernel support. + + Note that this has nothing to do with the network file systems NFS + or Coda; you can say N here even if you intend to use NFS or Coda. + + If you want to compile this driver as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read <file:Documentation/modules.txt>. The module + will be called nbd.o. + + If unsure, say N. + +XenoLinux virtual block device support +CONFIG_XENOLINUX_BLOCK + Xen can export virtual block devices which map back to extents of + blocks on the physical partitions. This option is needed for + xenolinux to make use of such devices when running as a Xen guest. + + If unsure, say Y. + +Per partition statistics in /proc/partitions +CONFIG_BLK_STATS + If you say yes here, your kernel will keep statistical information + for every partition. The information includes things as numbers of + read and write accesses, the number of merged requests etc. + + This is required for the full functionality of sar(8) and interesting + if you want to do performance tuning, by tweaking the elevator, e.g. + + If unsure, say N. + +ATA/IDE/MFM/RLL support +CONFIG_IDE + If you say Y here, your kernel will be able to manage low cost mass + storage units such as ATA/(E)IDE and ATAPI units. The most common + cases are IDE hard drives and ATAPI CD-ROM drives. + + If your system is pure SCSI and doesn't use these interfaces, you + can say N here. + + Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard + for mass storage units such as hard disks. It was designed by + Western Digital and Compaq Computer in 1984. It was then named + ST506. Quite a number of disks use the IDE interface. + + AT Attachment (ATA) is the superset of the IDE specifications. + ST506 was also called ATA-1. + + Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is + ATA-3. It provides support for larger disks (up to 8.4GB by means of + the LBA standard), more disks (4 instead of 2) and for other mass + storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is + ATA-4 and provides faster (and more CPU friendly) transfer modes + than previous PIO (Programmed processor Input/Output) from previous + ATA/IDE standards by means of fast DMA controllers. + + ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and + CD-ROM drives, similar in many respects to the SCSI protocol. + + SMART IDE (Self Monitoring, Analysis and Reporting Technology) was + designed in order to prevent data corruption and disk crash by + detecting pre hardware failure conditions (heat, access time, and + the like...).

Most people use + the newer enhanced driver, but this old one is still around for two + reasons. Some older systems have strange timing problems and seem to + work only with the old driver (which itself does not work with some + newer systems). The other reason is that the old driver is smaller, + since it lacks the enhanced functionality of the new one. This makes + it a good choice for systems with very tight memory restrictions, or + for systems with only older MFM/RLL/ESDI drives.

See the + text file <file:Documentation/networking/filter.txt> for more + information. + + You need to say Y here if you want to use PPP packet filtering + (see the CONFIG_PPP_FILTER option below). + + If unsure, say N. + +Network packet filtering (replaces ipchains) +CONFIG_NETFILTER + Netfilter is a framework for filtering and mangling network packets + that pass through your Linux box. + + The most common use of packet filtering is to run your Linux box as + a firewall protecting a local network from the Internet. The type of + firewall provided by this kernel support is called a "packet + filter", which means that it can reject individual network packets + based on type, source, destination etc. The other kind of firewall, + a "proxy-based" one, is more secure but more intrusive and more + bothersome to set up; it inspects the network traffic much more + closely, modifies it and has knowledge about the higher level + protocols, which a packet filter lacks. Moreover, proxy-based + firewalls often require changes to the programs running on the local + clients. Proxy-based firewalls don't need support by the kernel, but + they are often combined with a packet filter, which only works if + you say Y here. + + You should also say Y here if you intend to use your Linux box as + the gateway to the Internet for a local network of machines without + globally valid IP addresses. This is called "masquerading": if one + of the computers on your local network wants to send something to + the outside, your box can "masquerade" as that computer, i.e. it + forwards the traffic to the intended outside destination, but + modifies the packets to make it look like they came from the + firewall box itself. It works both ways: if the outside host + replies, the Linux box will silently forward the traffic to the + correct local computer. This way, the computers on your local net + are completely invisible to the outside world, even though they can + reach the outside and can receive replies. It is even possible to + run globally visible servers from within a masqueraded local network + using a mechanism called portforwarding. Masquerading is also often + called NAT (Network Address Translation). + + Another use of Netfilter is in transparent proxying: if a machine on + the local network tries to connect to an outside host, your Linux + box can transparently forward the traffic to a local server, + typically a caching proxy server. + + Various modules exist for netfilter which replace the previous + masquerading (ipmasqadm), packet filtering (ipchains), transparent + proxying, and portforwarding mechanisms. Please see + <file:Documentation/Changes> under "iptables" for the location of + these packages. + + Make sure to say N to "Fast switching" below if you intend to say Y + here, as Fast switching currently bypasses netfilter. + + Chances are that you should say Y here if you compile a kernel which + will run as a router and N for regular hosts. If unsure, say N. + +Network packet filtering debugging +CONFIG_NETFILTER_DEBUG + You can say Y here if you want to get additional messages useful in + debugging the netfilter code. + +Connection tracking (required for masq/NAT) +CONFIG_IP_NF_CONNTRACK + Connection tracking keeps a record of what packets have passed + through your machine, in order to figure out how they are related + into connections. + + This is required to do Masquerading or other kinds of Network + Address Translation (except for Fast NAT).

If you + say Y here, the TCP/IP stack will use a cryptographic challenge + protocol known as "SYN cookies" to enable legitimate users to + continue to connect, even when your machine is under attack. There + is no need for the legitimate users to change their TCP/IP software; + SYN cookies work transparently to them. For technical information + about SYN cookies, check out <http://cr.yp.to/syncookies.html>. + + If you are SYN flooded, the source address reported by the kernel is + likely to have been forged by the attacker; it is only reported as + an aid in tracing the packets to their actual source and should not + be taken as absolute truth. + + SYN cookies may prevent correct error reporting on clients when the + server is really overloaded.

Details about the Linux/Alpha booting process are contained in + the Linux/Alpha FAQ, accessible on the WWW from + <http://www.alphalinux.org/>. + + The usual way to load Linux on an Alpha machine is to use MILO + (a bootloader that lets you pass command line parameters to the + kernel just like lilo does for the x86 architecture) which can be + loaded either from ARC or can be installed directly as a permanent + firmware replacement from floppy (which requires changing a certain + jumper on the motherboard). If you want to do either of these, say N + here.

If unsure, say N. + +CONFIG_PCMCIA_SIBYTE + Say Y here to include support for the SiByte SOC's built-in PCMCIA + interface. Only ATA cards and CompactFlash are currently + supported. + +System V IPC +CONFIG_SYSVIPC + Inter Process Communication is a suite of library functions and + system calls which let processes (running programs) synchronize and + exchange information.

The + information includes things such as creation time, owning user, + command name, memory usage, controlling terminal etc. (the complete + list is in the struct acct in <file:include/linux/acct.h>). It is + up to the user level program to do useful things with this + information. This is generally a good idea, so say Y. + +Sysctl support +CONFIG_SYSCTL + The sysctl interface provides a means of dynamically changing + certain kernel parameters and variables on the fly without requiring + a recompile of the kernel or reboot of the system. The primary + interface consists of a system call, but if you say Y to "/proc + file system support", a tree of modifiable sysctl entries will be + generated beneath the /proc/sys directory. They are explained in the + files in <file:Documentation/sysctl/>. Note that enabling this + option will enlarge the kernel by at least 8 KB. + + As it is generally a good thing, you should say Y here unless + building a kernel for install/rescue disks or your system is very + limited in memory. + +# Choice: kcore +Kernel core (/proc/kcore) format +CONFIG_KCORE_ELF + If you enabled support for /proc file system then the file + /proc/kcore will contain the kernel core image. This can be used + in gdb: + + $ cd /usr/src/linux ; gdb vmlinux /proc/kcore + + You have two choices here: ELF and A.OUT. Selecting ELF will make + /proc/kcore appear in ELF core format as defined by the Executable + and Linking Format specification. Selecting A.OUT will choose the + old "a.out" format which may be necessary for some old versions + of binutils or on some architectures. + + This is especially useful if you have compiled the kernel with the + "-g" option to preserve debugging information. It is mainly used + for examining kernel data structures on the live kernel so if you + don't understand what this means or are not a kernel hacker, just + leave it at its default value ELF. + +Select a.out format for /proc/kcore +CONFIG_KCORE_AOUT + Not necessary unless you're using a very out-of-date binutils + version. You probably want KCORE_ELF. + +Kernel support for ELF binaries +CONFIG_BINFMT_ELF + ELF (Executable and Linkable Format) is a format for libraries and + executables used across different architectures and operating + systems. Saying Y here will enable your kernel to run ELF binaries + and enlarge it by about 13 KB. ELF support under Linux has now all + but replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC) + because it is portable (this does *not* mean that you will be able + to run executables from different architectures or operating systems + however) and makes building run-time libraries very easy. Many new + executables are distributed solely in ELF format. You definitely + want to say Y here. + + Information about ELF is contained in the ELF HOWTO available from + <http://www.tldp.org/docs.html#howto>. + + If you find that after upgrading from Linux kernel 1.2 and saying Y + here, you still can't run any ELF binaries (they just crash), then + you'll have to install the newest ELF runtime libraries, including + ld.so (check the file <file:Documentation/Changes> for location and + latest version). + + If you want to compile this as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read <file:Documentation/modules.txt>. The module + will be called binfmt_elf.o. Saying M or N here is dangerous because + some crucial programs on your system might be in ELF format. + +Kernel support for a.out binaries +CONFIG_BINFMT_AOUT + A.out (Assembler.OUTput) is a set of formats for libraries and + executables used in the earliest versions of UNIX. Linux used the + a.out formats QMAGIC and ZMAGIC until they were replaced with the + ELF format. + + As more and more programs are converted to ELF, the use for a.out + will gradually diminish. If you disable this option it will reduce + your kernel by one page. This is not much and by itself does not + warrant removing support. However its removal is a good idea if you + wish to ensure that absolutely none of your programs will use this + older executable format. If you don't know what to answer at this + point then answer Y. If someone told you "You need a kernel with + QMAGIC support" then you'll have to say Y here. You may answer M to + compile a.out support as a module and later load the module when you + want to use a program or library in a.out format. The module will be + called binfmt_aout.o. Saying M or N here is dangerous though, + because some crucial programs on your system might still be in A.OUT + format. + +OSF/1 v4 readv/writev compatibility +CONFIG_OSF4_COMPAT + Say Y if you are using OSF/1 binaries (like Netscape and Acrobat) + with v4 shared libraries freely available from Compaq.

For + this to work, you need to have the emulator /usr/bin/em86 in place. + + You can get the same functionality by saying N here and saying Y to + "Kernel support for MISC binaries". + + You may answer M to compile the emulation support as a module and + later load the module when you want to use a Linux/Intel binary. The + module will be called binfmt_em86.o. If unsure, say Y. + +Kernel support for SOM binaries +CONFIG_BINFMT_SOM + SOM is a binary executable format inherited from HP/UX. Say Y here + to be able to load and execute SOM binaries directly. + +Kernel support for MISC binaries +CONFIG_BINFMT_MISC + If you say Y here, it will be possible to plug wrapper-driven binary + formats into the kernel. You will like this especially when you use + programs that need an interpreter to run like Java, Python or + Emacs-Lisp. It's also useful if you often run DOS executables under + the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from + <http://www.tldp.org/docs.html#howto>). Once you have + registered such a binary class with the kernel, you can start one of + those programs simply by typing in its name at a shell prompt; Linux + will automatically feed it to the correct interpreter. + + You can do other nice things, too. Read the file + <file:Documentation/binfmt_misc.txt> to learn how to use this + feature, and <file:Documentation/java.txt> for information about how + to include Java support. + + You must say Y to "/proc file system support" (CONFIG_PROC_FS) to + use this part of the kernel. + + You may say M here for module support and later load the module when + you have use for it; the module is called binfmt_misc.o. If you + don't know what to answer at this point, say Y. + +Kernel support for JAVA binaries +CONFIG_BINFMT_JAVA + If you say Y here, the kernel will load and execute Java J-code + binaries directly.

It is safe to say N. + +Enable loadable module support +CONFIG_MODULES + Kernel modules are small pieces of compiled code which can be + inserted in or removed from the running kernel, using the programs + insmod and rmmod. This is described in the file + <file:Documentation/modules.txt>, including the fact that you have + to say "make modules" in order to compile the modules that you chose + during kernel configuration. Modules can be device drivers, file + systems, binary executable formats, and so on. If you think that you + may want to make use of modules with this kernel in the future, then + say Y here. If unsure, say Y. + +Set version information on all symbols for modules +CONFIG_MODVERSIONS + Usually, modules have to be recompiled whenever you switch to a new + kernel. Saying Y here makes it possible, and safe, to use the + same modules even after compiling a new kernel; this requires the + program modprobe. All the software needed for module support is in + the modutils package (check the file <file:Documentation/Changes> + for location and latest version). NOTE: if you say Y here but don't + have the program genksyms (which is also contained in the above + mentioned modutils package), then the building of your kernel will + fail. If you are going to use modules that are generated from + non-kernel sources, you would benefit from this option. Otherwise + it's not that important. So, N ought to be a safe bet. + +Kernel module loader support +CONFIG_KMOD + Normally when you have selected some drivers and/or file systems to + be created as loadable modules, you also have the responsibility to + load the corresponding modules (using the programs insmod or + modprobe) before you can use them. If you say Y here however, the + kernel will be able to load modules for itself: when a part of the + kernel needs a module, it runs modprobe with the appropriate + arguments, thereby loading the module if it is available. (This is a + replacement for kerneld.) Say Y here and read about configuring it + in <file:Documentation/kmod.txt>. + +ARP daemon support +CONFIG_ARPD + Normally, the kernel maintains an internal cache which maps IP + addresses to hardware addresses on the local network, so that + Ethernet/Token Ring/ etc. frames are sent to the proper address on + the physical networking layer. For small networks having a few + hundred directly connected hosts or less, keeping this address + resolution (ARP) cache inside the kernel works well. However, + maintaining an internal ARP cache does not work well for very large + switched networks, and will use a lot of kernel memory if TCP/IP + connections are made to many machines on the network. + + If you say Y here, the kernel's internal ARP cache will never grow + to more than 256 entries (the oldest entries are expired in a LIFO + manner) and communication will be attempted with the user space ARP + daemon arpd. Arpd then answers the address resolution request either + from its own cache or by asking the net. + + This code is experimental and also obsolete. If you want to use it, + you need to find a version of the daemon arpd on the net somewhere, + and you should also say Y to "Kernel/User network link driver", + below. If unsure, say N. + +TCP/IP networking +CONFIG_INET + These are the protocols used on the Internet and on most local + Ethernets. It is highly recommended to say Y here (this will enlarge + your kernel by about 144 KB), since some programs (e.g. the X window + system) use TCP/IP even if your machine is not connected to any + other computer. You will get the so-called loopback device which + allows you to ping yourself (great fun, that!). + + For an excellent introduction to Linux networking, please read the + NET-3-HOWTO, available from + <http://www.tldp.org/docs.html#howto>. + + This option is also necessary if you want to use the full power of + term (term is a program which gives you almost full Internet + connectivity if you have a regular dial up shell account on some + Internet connected Unix computer; for more information, read + <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). + + If you say Y here and also to "/proc file system support" and + "Sysctl support" below, you can change various aspects of the + behaviour of the TCP/IP code by writing to the (virtual) files in + /proc/sys/net/ipv4/*; the options are explained in the file + <file:Documentation/networking/ip-sysctl.txt>. + + Short answer: say Y. + +IP multicasting +CONFIG_IP_MULTICAST + This is code for addressing several networked computers at once, + enlarging your kernel by about 2 KB. You need multicasting if you + intend to participate in the MBONE, a high bandwidth network on top + of the Internet which carries audio and video broadcasts. More + information about the MBONE is on the WWW at + <http://www-itg.lbl.gov/mbone/>.

For most people, it's + safe to say N. + +Advanced router +CONFIG_IP_ADVANCED_ROUTER + If you intend to run your Linux box mostly as a router, i.e. as a + computer that forwards and redistributes network packets, say Y; you + will then be presented with several options that allow more precise + control about the routing process. + + The answer to this question won't directly affect the kernel: + answering N will just cause the configurator to skip all the + questions about advanced routing. + + Note that your box can only act as a router if you enable IP + forwarding in your kernel; you can do that by saying Y to "/proc + file system support" and "Sysctl support" below and executing the + line + + echo "1" > /proc/sys/net/ipv4/ip_forward + + at boot time after the /proc file system has been mounted. + + If you turn on IP forwarding, you will also get the rp_filter, which + automatically rejects incoming packets if the routing table entry + for their source address doesn't match the network interface they're + arriving on. This has security advantages because it prevents the + so-called IP spoofing, however it can pose problems if you use + asymmetric routing (packets from you to a host take a different path + than packets from that host to you) or if you operate a non-routing + host which has several IP addresses on different interfaces. To turn + rp_filter off use: + + echo 0 > /proc/sys/net/ipv4/conf/<device>/rp_filter + or + echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter + + If unsure, say N here. + +Policy routing +CONFIG_IP_MULTIPLE_TABLES + Normally, a router decides what to do with a received packet based + solely on the packet's final destination address. If you say Y here, + the Linux router will also be able to take the packet's source + address into account. Furthermore, if you also say Y to "Use TOS + value as routing key" below, the TOS (Type-Of-Service) field of the + packet can be used for routing decisions as well.

The module + will be called aic7xxx_old.o. + +Enable tagged command queueing (TCQ) by default +CONFIG_AIC7XXX_OLD_TCQ_ON_BY_DEFAULT + This option causes the aic7xxx driver to attempt to use Tagged + Command Queueing (TCQ) on all devices that claim to support it. + + TCQ is a feature of SCSI-2 which improves performance: the host + adapter can send several SCSI commands to a device's queue even if + previous commands haven't finished yet. Because the device is + intelligent, it can optimize its operations (like head positioning) + based on its own request queue. Not all devices implement this + correctly. + + If you say Y here, you can still turn off TCQ on troublesome devices + with the use of the tag_info boot parameter. See the file + <file:drivers/scsi/README.aic7xxx> for more information on that and + other aic7xxx setup commands. If this option is turned off, you may + still enable TCQ on known good devices by use of the tag_info boot + parameter. + + If you are unsure about your devices then it is safest to say N + here. + + However, TCQ can increase performance on some hard drives by as much + as 50% or more, so it is recommended that if you say N here, you + should at least read the <file:drivers/scsi/README.aic7xxx> file so + you will know how to enable this option manually should your drives + prove to be safe in regards to TCQ. + + Conversely, certain drives are known to lock up or cause bus resets + when TCQ is enabled on them. If you have a Western Digital + Enterprise SCSI drive for instance, then don't even bother to enable + TCQ on it as the drive will become unreliable, and it will actually + reduce performance. + +Default number of TCQ commands per device +CONFIG_AIC7XXX_OLD_CMDS_PER_DEVICE + Specify the number of commands you would like to allocate per SCSI + device when Tagged Command Queueing (TCQ) is enabled on that device. + + Reasonable figures are in the range of 8 to 24 commands per device, + but depending on hardware could be increased or decreased from that + figure. If the number is too high for any particular device, the + driver will automatically compensate usually after only 10 minutes + of uptime. It will not hinder performance if some of your devices + eventually have their command depth reduced, but is a waste of + memory if all of your devices end up reducing this number down to a + more reasonable figure. + + NOTE: Certain very broken drives are known to lock up when given + more commands than they like to deal with. Quantum Fireball drives + are the most common in this category. For the Quantum Fireball + drives it is suggested to use no more than 8 commands per device. + + Default: 8 + +Collect statistics to report in /proc +CONFIG_AIC7XXX_OLD_PROC_STATS + This option tells the driver to keep track of how many commands have + been sent to each particular device and report that information to + the user via the /proc/scsi/aic7xxx/n file, where n is the number of + the aic7xxx controller you want the information on. This adds a + small amount of overhead to each and every SCSI command the aic7xxx + driver handles, so if you aren't really interested in this + information, it is best to leave it disabled.

The module + will be called ncr53c8xx.o. + +SYM53C8XX Version 1 SCSI support +CONFIG_SCSI_SYM53C8XX + This driver supports all the features of recent 53C8XX chips (used + in PCI SCSI controllers), notably the hardware phase mismatch + feature of the SYM53C896. + + Older versions of the 53C8XX chips are not supported by this + driver. If your system uses either a 810 rev. < 16, a 815, or a 825 + rev. < 16 PCI SCSI processor, you must use the generic NCR53C8XX + driver ("NCR53C8XX SCSI support" above) or configure both the + NCR53C8XX and this SYM53C8XX drivers either as module or linked to + the kernel image. + + When both drivers are linked into the kernel, the SYM53C8XX driver + is called first at initialization and you can use the 'excl=ioaddr' + driver boot option to exclude attachment of adapters by the + SYM53C8XX driver. For example, entering + 'sym53c8xx=excl:0xb400,excl=0xc000' at the lilo prompt prevents + adapters at io address 0xb400 and 0xc000 from being attached by the + SYM53C8XX driver, thus allowing the NCR53C8XX driver to attach them. + The 'excl' option is also supported by the NCR53C8XX driver. + + Please read <file:drivers/scsi/README.ncr53c8xx> for more + information. + + If you want to compile the driver as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read <file:Documentation/modules.txt>. The module + will be called sym53c8xx.o. + +Synchronous transfer frequency in MHz +CONFIG_SCSI_NCR53C8XX_SYNC + The SCSI Parallel Interface-2 Standard defines 5 classes of transfer + rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers + are respectively the maximum data transfer rates in mega-transfers + per second for each class. For example, a FAST-20 Wide 16 device is + able to transfer data at 20 million 16 bit packets per second for a + total rate of 40 MB/s. + + You may specify 0 if you want to only use asynchronous data + transfers. This is the safest and slowest option. Otherwise, specify + a value between 5 and 80, depending on the capability of your SCSI + controller. The higher the number, the faster the data transfer. + Note that 80 should normally be ok since the driver decreases the + value automatically according to the controller's capabilities. + + Your answer to this question is ignored for controllers with NVRAM, + since the driver will get this information from the user set-up. It + also can be overridden using a boot setup option, as follows + (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate + for FAST-20 synchronous data transfer (20 mega-transfers per + second). + + The normal answer therefore is not to go with the default but to + select the maximum value 80 allowing the driver to use the maximum + value supported by each controller. If this causes problems with + your SCSI devices, you should come back and decrease the value. + + There is no safe option other than using good cabling, right + terminations and SCSI conformant devices. + +Use normal IO +CONFIG_SCSI_NCR53C8XX_IOMAPPED + If you say Y here, the driver will use normal IO, as opposed to + memory mapped IO. Memory mapped IO has less latency than normal IO + and works for most Intel-based hardware. Under Linux/Alpha only + normal IO is currently supported by the driver and so, this option + has no effect on those systems. + + The normal answer therefore is N; try Y only if you encounter SCSI + related problems. + +Not allow targets to disconnect +CONFIG_SCSI_NCR53C8XX_NO_DISCONNECT + This option is only provided for safety if you suspect some SCSI + device of yours to not support properly the target-disconnect + feature. In that case, you would say Y here. In general however, to + not allow targets to disconnect is not reasonable if there is more + than 1 device on a SCSI bus. The normal answer therefore is N. + +Default tagged command queue depth +CONFIG_SCSI_NCR53C8XX_DEFAULT_TAGS + "Tagged command queuing" is a feature of SCSI-2 which improves + performance: the host adapter can send several SCSI commands to a + device's queue even if previous commands haven't finished yet. + Because the device is intelligent, it can optimize its operations + (like head positioning) based on its own request queue. Some SCSI + devices don't implement this properly; if you want to disable this + feature, enter 0 or 1 here (it doesn't matter which). + + The default value is 8 and should be supported by most hard disks. + This value can be overridden from the boot command line using the + 'tags' option as follows (example): + 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to + 4, set queue depth to 16 for target 2 and target 3 on controller 0 + and set queue depth to 10 for target 0 / lun 2 on controller 1. + + The normal answer therefore is to go with the default 8 and to use + a boot command line option for devices that need to use a different + command queue depth. + + There is no safe option other than using good SCSI devices. + +Maximum number of queued commands +CONFIG_SCSI_NCR53C8XX_MAX_TAGS + This option allows you to specify the maximum number of commands + that can be queued to any device, when tagged command queuing is + possible. The default value is 32. Minimum is 2, maximum is 64. + Modern hard disks are able to support 64 tags and even more, but + do not seem to be faster when more than 32 tags are being used. + + So, the normal answer here is to go with the default value 32 unless + you are using very large hard disks with large cache (>= 1 MB) that + are able to take advantage of more than 32 tagged commands. + + There is no safe option and the default answer is recommended. + +Assume boards are SYMBIOS compatible +CONFIG_SCSI_NCR53C8XX_SYMBIOS_COMPAT + This option allows you to enable some features depending on GPIO + wiring. These General Purpose Input/Output pins can be used for + vendor specific features or implementation of the standard SYMBIOS + features. Genuine SYMBIOS controllers use GPIO0 in output for + controller LED and GPIO3 bit as a flag indicating + singled-ended/differential interface. The Tekram DC-390U/F boards + uses a different GPIO wiring. + + Your answer to this question is ignored if all your controllers have + NVRAM, since the driver is able to detect the board type from the + NVRAM format. + + If all the controllers in your system are genuine SYMBIOS boards or + use BIOS and drivers from SYMBIOS, you would want to say Y here, + otherwise N. N is the safe answer. + +Enable traffic profiling +CONFIG_SCSI_NCR53C8XX_PROFILE + This option allows you to enable profiling information gathering. + These statistics are not very accurate due to the low frequency + of the kernel clock (100 Hz on i386) and have performance impact + on systems that use very fast devices. + + The normal answer therefore is N. + +Include support for the NCR PQS/PDS SCSI card +CONFIG_SCSI_NCR53C8XX_PQS_PDS + Say Y here if you have a special SCSI adapter produced by NCR + corporation called a PCI Quad SCSI or PCI Dual SCSI. You do not need + this if you do not have one of these adapters. However, since this + device is detected as a specific PCI device, this option is quite + safe. + + The common answer here is N, but answering Y is safe. + +Workbit NinjaSCSI-32Bi/UDE support +CONFIG_SCSI_NSP32 + This is support for the Workbit NinjaSCSI-32Bi/UDE PCI/Cardbus + SCSI host adapter.

When looking into papers describing the + ANSI-SCSI-standard, this assignment of drives appears to be wrong. + The SCSI-standard follows a hardware-hierarchy which says that id 7 + has the highest priority and id 0 the lowest. Therefore, the host + adapters are still today everywhere placed as SCSI-id 7 by default. + In the SCSI-standard, the drive letters express the priority of the + disk. C: should be the hard disk, or a partition on it, with the + highest priority. This must therefore be the disk with the highest + SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the + original definition of the SCSI-standard as also industrial- and + process-control-machines, like VME-CPUs running under realtime-OSes + (e.g. LynxOS, OS9) do. + + If you like to run Linux on your MCA-machine with the same + assignment of hard disks as seen from e.g. DOS or OS/2 on your + machine, which is in addition conformant to the SCSI-standard, you + must say Y here. This is also necessary for MCA-Linux users who want + to keep downward compatibility to older releases of the + IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than + June 1997). + + If you like to have the lowest SCSI-id assigned as drive C:, as + modern SCSI-BIOSes do, which does not conform to the standard, but + is widespread and common in the PC-world of today, you must say N + here.

Ask your access provider if you are not sure and + answer Y, just in case. You will still be able to use plain SLIP. If + you plan to use SLiRP, the SLIP emulator (available from + <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which + allows you to use SLIP over a regular dial up shell connection, you + definitely want to say Y here. The NET-3-HOWTO, available from + <http://www.tldp.org/docs.html#howto>, explains how to configure + CSLIP. This won't enlarge your kernel. + +Keepalive and linefill +CONFIG_SLIP_SMART + Adds additional capabilities to the SLIP driver to support the + RELCOM line fill and keepalive monitoring. Ideal on poor quality + analogue lines. + +Six bit SLIP encapsulation +CONFIG_SLIP_MODE_SLIP6 + Just occasionally you may need to run IP over hostile serial + networks that don't pass all control characters or are only seven + bit. Saying Y here adds an extra mode you can use with SLIP: + "slip6". In this mode, SLIP will only send normal ASCII symbols over + the serial device. Naturally, this has to be supported at the other + end of the link as well. It's good enough, for example, to run IP + over the async ports of a Camtec JNT Pad. If unsure, say N. + +PPP (point-to-point protocol) support +CONFIG_PPP + PPP (Point to Point Protocol) is a newer and better SLIP. It serves + the same purpose: sending Internet traffic over telephone (and other + serial) lines. Ask your access provider if they support it, because + otherwise you can't use it; most Internet access providers these + days support PPP rather than SLIP. + + To use PPP, you need an additional program called pppd as described + in the PPP-HOWTO, available at + <http://www.tldp.org/docs.html#howto>. Make sure that you have + the version of pppd recommended in <file:Documentation/Changes>. + The PPP option enlarges your kernel by about 16 KB. + + There are actually two versions of PPP: the traditional PPP for + asynchronous lines, such as regular analog phone lines, and + synchronous PPP which can be used over digital ISDN lines for + example. If you want to use PPP over phone lines or other + asynchronous serial lines, you need to say Y (or M) here and also to + the next option, "PPP support for async serial ports". For PPP over + synchronous lines, you should say Y (or M) here and to "Support + synchronous PPP", below. + + This driver is also available as a module ( = code which can be + inserted in and removed from the running kernel whenever you want). + If you said Y to "Version information on all symbols" above, then + you cannot compile the PPP driver into the kernel; you can then only + compile it as a module. The module will be called ppp_generic.o. + If you want to compile it as a module, say M here and read + <file:Documentation/modules.txt> as well as + <file:Documentation/networking/net-modules.txt>. + +PPP multilink support +CONFIG_PPP_MULTILINK + PPP multilink is a protocol (defined in RFC 1990) which allows you + to combine several (logical or physical) lines into one logical PPP + connection, so that you can utilize your full bandwidth. + + This has to be supported at the other end as well and you need a + version of the pppd daemon which understands the multilink protocol. + + If unsure, say N. + +PPP filtering +CONFIG_PPP_FILTER + Say Y here if you want to be able to filter the packets passing over + PPP interfaces. This allows you to control which packets count as + activity (i.e. which packets will reset the idle timer or bring up + a demand-dialled link) and which packets are to be dropped entirely. + You need to say Y here if you wish to use the pass-filter and + active-filter options to pppd. + + If unsure, say N. + +PPP support for async serial ports +CONFIG_PPP_ASYNC + Say Y (or M) here if you want to be able to use PPP over standard + asynchronous serial ports, such as COM1 or COM2 on a PC. If you use + a modem (not a synchronous or ISDN modem) to contact your ISP, you + need this option. + + If you want to compile the driver as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read <file:Documentation/modules.txt>.

The module + will be called ppp_synctty.o. + +PPP Deflate compression +CONFIG_PPP_DEFLATE + Support for the Deflate compression method for PPP, which uses the + Deflate algorithm (the same algorithm that gzip uses) to compress + each PPP packet before it is sent over the wire. The machine at the + other end of the PPP link (usually your ISP) has to support the + Deflate compression method as well for this to be useful. Even if + they don't support it, it is safe to say Y here. + + If you want to compile the driver as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read <file:Documentation/modules.txt>. The module + will be called ppp_deflate.o. + +PPP BSD-Compress compression +CONFIG_PPP_BSDCOMP + Support for the BSD-Compress compression method for PPP, which uses + the LZW compression method to compress each PPP packet before it is + sent over the wire. The machine at the other end of the PPP link + (usually your ISP) has to support the BSD-Compress compression + method as well for this to be useful. Even if they don't support it, + it is safe to say Y here. + + The PPP Deflate compression method ("PPP Deflate compression", + above) is preferable to BSD-Compress, because it compresses better + and is patent-free. + + Note that the BSD compression code will always be compiled as a + module; it is called bsd_comp.o and will show up in the directory + modules once you have said "make modules". If unsure, say N. + +PPP over Ethernet +CONFIG_PPPOE + Support for PPP over Ethernet. + + This driver requires the current pppd from the "ppp" CVS repository + on cvs.samba.org. The required support will be present in the next + ppp release (2.4.2). + +Wireless LAN (non-hamradio) +CONFIG_NET_RADIO + Support for wireless LANs and everything having to do with radio, + but not with amateur radio or FM broadcasting. + + Saying Y here also enables the Wireless Extensions (creates + /proc/net/wireless and enables ifconfig access).

If you want to compile it as + a module, say M here and read <file:Documentation/modules.txt>. + +CONFIG_USB_GADGET + USB is a master/slave protocol, organized with one master + host (such as a PC) controlling up to 127 peripheral devices. + The USB hardware is asymmetric, which makes it easier to set up: + you can't connect two "to-the-host" connectors to each other. + + Linux can run in the host, or in the peripheral. In both cases + you need a low level bus controller driver, and some software + talking to it. Peripheral controllers are often discrete silicon, + or are integrated with the CPU in a microcontroller. The more + familiar host side controllers have names like like "EHCI", "OHCI", + or "UHCI", and are usually integrated into southbridges on PC + motherboards. + + Enable this configuration option if you want to run Linux inside + a USB peripheral device. Configure one hardware driver for your + peripheral/device side bus controller, and a "gadget driver" for + your peripheral protocol. (If you use modular gadget drivers, + you may configure more than one.) + + If in doubt, say "N" and don't enable these drivers; most people + don't have this kind of hardware (except maybe inside Linux PDAs). + +CONFIG_USB_NET2280 + NetChip 2280 is a PCI based USB peripheral controller which + supports both full and high speed USB 2.0 data transfers. + + It has six configurable endpoints, as well as endpoint zero + (for control transfers) and several endpoints with dedicated + functions. + + Say "y" to link the driver statically, or "m" to build a + dynamically linked module called "net2280" and force all + gadget drivers to also be dynamically linked. + +CONFIG_USB_ZERO + Gadget Zero is a two-configuration device. It either sinks and + sources bulk data; or it loops back a configurable number of + transfers. It also implements control requests, for "chapter 9" + conformance. The driver needs only two bulk-capable endpoints, so + it can work on top of most device-side usb controllers. It's + useful for testing, and is also a working example showing how + USB "gadget drivers" can be written. + + Make this be the first driver you try using on top of any new + USB peripheral controller driver. Then you can use host-side + test software, like the "usbtest" driver, to put your hardware + and its driver through a basic set of functional tests. + + Gadget Zero also works with the host-side "usb-skeleton" driver, + and with many kinds of host-side test software. You may need + to tweak product and vendor IDs before host software knows about + this device, and arrange to select an appropriate configuration. + + Say "y" to link the driver statically, or "m" to build a + dynamically linked module called "g_zero". + +CONFIG_USB_ETH + This driver implements Ethernet style communication, in either + of two ways: + + - The "Communication Device Class" (CDC) Ethernet Control Model. + That protocol is often avoided with pure Ethernet adapters, in + favor of simpler vendor-specific hardware, but is widely + supported by firmware for smart network devices. + + - On hardware can't implement that protocol, a simpler approach + is used, placing fewer demands on USB. + + Within the USB device, this gadget driver exposes a network device + "usbX", where X depends on what other networking devices you have. + Treat it like a two-node Ethernet link: host, and gadget. + + The Linux-USB host-side "usbnet" driver interoperates with this + driver, so that deep I/O queues can be supported. On 2.4 kernels, + use "CDCEther" instead, if you're using the CDC option. That CDC + mode should also interoperate with standard CDC Ethernet class + drivers on other host operating systems. + + Say "y" to link the driver statically, or "m" to build a + dynamically linked module called "g_ether". + +Always do synchronous disk IO for UBD +CONFIG_BLK_DEV_UBD_SYNC + The User-Mode Linux port includes a driver called UBD which will let + you access arbitrary files on the host computer as block devices. + Writes to such a block device are not immediately written to the + host's disk; this may cause problems if, for example, the User-Mode + Linux 'Virtual Machine' uses a journalling file system and the host + computer crashes. + + Synchronous operation (i.e. always writing data to the host's disk + immediately) is configurable on a per-UBD basis by using a special + kernel command line option. Alternatively, you can say Y here to + turn on synchronous operation by default for all block. + + If you're running a journalling file system (like reiserfs, for + example) in your virtual machine, you will want to say Y here. If + you care for the safety of the data in your virtual machine, Y is a + wise choice too. In all other cases (for example, if you're just + playing around with User-Mode Linux) you can choose N. + +Enable ptrace proxy +CONFIG_PT_PROXY + This option enables a debugging interface which allows gdb to debug + the kernel without needing to actually attach to kernel threads. + If you want to do kernel debugging, say Y here; otherwise say N. + +Management console +CONFIG_MCONSOLE + The user mode linux management console is a low-level interface to + the kernel, somewhat like the i386 SysRq interface. Since there is + a full-blown operating system running under every user mode linux + instance, there is much greater flexibility possible than with the + SysRq mechanism. + + If you answer 'Y' to this option, to use this feature, you need the + mconsole client (called uml_mconsole) which is present in CVS in + 2.4.5-9um and later (path /tools/mconsole), and is also in the + distribution RPM package in 2.4.6 and later. + + It is safe to say 'Y' here. + +Enable kernel debugging symbols +CONFIG_DEBUGSYM + When this is enabled, the User-Mode Linux binary will include + debugging symbols.

If you're unsure, say N. + +Host filesystem +CONFIG_HOSTFS + While the User-Mode Linux port uses its own root file system for + booting and normal file access, this module lets the UML user + access files stored on the host.

This option will only + work with a 2.4 host, unless you've applied the TUN/TAP patch to + your 2.2 host kernel. + + To use this transport, your host kernel must have support for TUN/TAP + devices, either built-in or as a module. + +Multicast transport +CONFIG_UML_NET_MCAST + This Multicast User-Mode Linux network transport allows multiple + UMLs (even ones running on different host machines!) to talk to + each other over a virtual ethernet network. However, it requires + at least one UML with one of the other transports to act as a + bridge if any of them need to be able to talk to their hosts or any + other IP machines. + + To use this, your host kernel(s) must support IP Multicasting. + + For more information, see + <http://user-mode-linux.sourceforge.net/networking.html> That site + has examples of the UML command line to use to enable Multicast + networking, and notes about the security of this approach. + + If you need UMLs on multiple physical hosts to communicate as if + they shared an Ethernet network, say Y.

If you don't need to network UMLs say N to each of + the transports. + +SLIP transport +CONFIG_UML_NET_SLIP + The Slip User-Mode Linux network transport allows a running UML to + network with its host over a point-to-point link.

If you are fine-tuning reiserfs, say Y, + otherwise say N. + +Second extended fs support +CONFIG_EXT2_FS + This is the de facto standard Linux file system (method to organize + files on a storage device) for hard disks. + + You want to say Y here, unless you intend to use Linux exclusively + from inside a DOS partition using the UMSDOS file system. The + advantage of the latter is that you can get away without + repartitioning your hard drive (which often implies backing + everything up and restoring afterwards); the disadvantage is that + Linux becomes susceptible to DOS viruses and that UMSDOS is somewhat + slower than ext2fs. Even if you want to run Linux in this fashion, + it might be a good idea to have ext2fs around: it enables you to + read more floppy disks and facilitates the transition to a *real* + Linux partition later. Another (rare) case which doesn't require + ext2fs is a diskless Linux box which mounts all files over the + network using NFS (in this case it's sufficient to say Y to "NFS + file system support" below). Saying Y here will enlarge your kernel + by about 44 KB. + + The Ext2fs-Undeletion mini-HOWTO, available from + <http://www.tldp.org/docs.html#howto>, gives information about + how to retrieve deleted files on ext2fs file systems. + + To change the behaviour of ext2 file systems, you can use the tune2fs + utility ("man tune2fs"). To modify attributes of files and + directories on ext2 file systems, use chattr ("man chattr"). + + Ext2fs partitions can be read from within DOS using the ext2tool + command line tool package (available from + <ftp://ibiblio.org/pub/Linux/system/filesystems/ext2/>) and from + within Windows NT using the ext2nt command line tool package from + <ftp://ibiblio.org/pub/Linux/utils/dos/>.

The + module will be called ext2.o. Be aware however that the file system + of your root partition (the one containing the directory /) cannot + be compiled as a module, and so this could be dangerous. Most + everyone wants to say Y here. + +Ext3 journalling file system support (EXPERIMENTAL) +CONFIG_EXT3_FS + This is the journalling version of the Second extended file system + (often called ext3), the de facto standard Linux file system + (method to organize files on a storage device) for hard disks. + + The journalling code included in this driver means you do not have + to run e2fsck (file system checker) on your file systems after a + crash. The journal keeps track of any changes that were being made + at the time the system crashed, and can ensure that your file system + is consistent without the need for a lengthy check. + + Other than adding the journal to the file system, the on-disk format + of ext3 is identical to ext2. It is possible to freely switch + between using the ext3 driver and the ext2 driver, as long as the + file system has been cleanly unmounted, or e2fsck is run on the file + system. + + To add a journal on an existing ext2 file system or change the + behaviour of ext3 file systems, you can use the tune2fs utility ("man + tune2fs"). To modify attributes of files and directories on ext3 + file systems, use chattr ("man chattr"). You need to be using + e2fsprogs version 1.20 or later in order to create ext3 journals + (available at <http://sourceforge.net/projects/e2fsprogs/>). + + If you want to compile this file system as a module ( = code which + can be inserted in and removed from the running kernel whenever you + want), say M here and read <file:Documentation/modules.txt>. The + module will be called ext3.o. Be aware however that the file system + of your root partition (the one containing the directory /) cannot + be compiled as a module, and so this may be dangerous. + +Journal Block Device support (JBD for ext3) (EXPERIMENTAL) +CONFIG_JBD + This is a generic journalling layer for block devices. It is + currently used by the ext3 file system, but it could also be used to + add journal support to other file systems or block devices such as + RAID or LVM. + + If you are using the ext3 file system, you need to say Y here.

If you are compiling ext3 into the kernel, + you cannot compile this code as a module. + +JBD (ext3) debugging support +CONFIG_JBD_DEBUG + If you are using the ext3 journalling file system (or potentially any + other file system/device using JBD), this option allows you to + enable debugging output while the system is running, in order to + help track down any problems you are having. By default the + debugging output will be turned off. + + If you select Y here, then you will be able to turn on debugging + with "echo N > /proc/sys/fs/jbd-debug", where N is a number between + 1 and 5, the higher the number, the more debugging output is + generated. To turn debugging off again, do + "echo 0 > /proc/sys/fs/jbd-debug". + +Buffer Head tracing (DEBUG) +CONFIG_BUFFER_DEBUG + If you are a kernel developer working with file systems or in the + block device layer, this buffer head tracing may help you to track + down bugs in your code. This enables some debugging macros + (BUFFER_TRACE, etc.) which allow you to track the state of a buffer + through various layers of code. The debugging code is used + primarily by ext3 and JBD code. + + Because this option adds considerably to the size of each buffer, + most people will want to say N here. + +BeOS filesystem support (BeFS) (read only) +CONFIG_BEFS_FS + The BeOS File System (BeFS) is the native file system of Be, Inc's + BeOS. Notable features include support for arbitrary attributes + on files and directories, and database-like indices on selected + attributes. (Also note that this driver doesn't make those features + available at this time).

Note that the file system of your root + partition (the one containing the directory /) cannot be compiled as + a module. + +Compressed ROM file system support +CONFIG_CRAMFS + Saying Y here includes support for CramFs (Compressed ROM File + System). CramFs is designed to be a simple, small, and compressed + file system for ROM based embedded systems. CramFs is read-only, + limited to 256MB file systems (with 16MB files), and doesn't support + 16/32 bits uid/gid, hard links and timestamps. + + See <file:Documentation/filesystems/cramfs.txt> and + <file:fs/cramfs/README> for further information. + + If you want to compile this as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read <file:Documentation/modules.txt>.

The module + will be called isofs.o. + +Microsoft Joliet CD-ROM extensions +CONFIG_JOLIET + Joliet is a Microsoft extension for the ISO 9660 CD-ROM file system + which allows for long filenames in unicode format (unicode is the + new 16 bit character code, successor to ASCII, which encodes the + characters of almost all languages of the world; see + <http://www.unicode.org/> for more information). Say Y here if you + want to be able to read Joliet CD-ROMs under Linux. + +Transparent decompression extension +CONFIG_ZISOFS + This is a Linux-specific extension to RockRidge which lets you store + data in compressed form on a CD-ROM and have it transparently + decompressed when the CD-ROM is accessed. See + <http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools + necessary to create such a filesystem. Say Y here if you want to be + able to read such compressed CD-ROMs. + +UDF file system support (read-only) +CONFIG_UDF_FS + This is the new file system used on some CD-ROMs and DVDs. Say Y if + you intend to mount DVD discs or CDRW's written in packet mode, or + if written to by other UDF utilities, such as DirectCD. This UDF + file system support is read-only. If you want to write to UDF + file systems on some media, you need to say Y to "UDF read-write + support" below in addition.

You will then be able to mount partitions or + diskettes with FAT-based file systems and transparently access the + files on them, i.e. MSDOS files will look and behave just like all + other Unix files. + + This FAT support is not a file system in itself, it only provides + the foundation for the other file systems. You will have to say Y or + M to at least one of "MSDOS fs support" or "VFAT fs support" in + order to make use of it. + + Another way to read and write MSDOS floppies and hard drive + partitions from within Linux (but not transparently) is with the + mtools ("man mtools") program suite. You don't need to say Y here in + order to do that. + + If you need to move large files on floppies between a DOS and a + Linux box, say Y here, mount the floppy under Linux with an MSDOS + file system and use GNU tar's M option. GNU tar is a program + available for Unix and DOS ("man tar" or "info tar"). + + It is now also becoming possible to read and write compressed FAT + file systems; read <file:Documentation/filesystems/fat_cvf.txt> for + details. + + The FAT support will enlarge your kernel by about 37 KB.

The advantage of this is that you can + get away without repartitioning your hard drive (which often implies + backing everything up and restoring afterwards) and hence you're + able to quickly try out Linux or show it to your friends; the + disadvantage is that Linux becomes susceptible to DOS viruses and + that UMSDOS is somewhat slower than ext2fs. Another use of UMSDOS + is to write files with long unix filenames to MSDOS floppies; it + also allows Unix-style soft-links and owner/permissions of files on + MSDOS floppies.

If unsure, say N. + +/proc file system support +CONFIG_PROC_FS + This is a virtual file system providing information about the status + of the system. "Virtual" means that it doesn't take up any space on + your hard disk: the files are created on the fly by the kernel when + you try to access them. Also, you cannot read the files with older + version of the program less: you need to use more or cat. + + It's totally cool; for example, "cat /proc/interrupts" gives + information about what the different IRQs are used for at the moment + (there is a small number of Interrupt ReQuest lines in your computer + that are used by the attached devices to gain the CPU's attention -- + often a source of trouble if two devices are mistakenly configured + to use the same IRQ). The program procinfo to display some + information about your system gathered from the /proc file system. + + Before you can use the /proc file system, it has to be mounted, + meaning it has to be given a location in the directory hierarchy. + That location should be /proc.

"Mounting files" means that the client can access + the files with usual UNIX commands as if they were sitting on the + client's hard disk. For this to work, the server must run the + programs nfsd and mountd (but does not need to have NFS file system + support enabled in its kernel). NFS is explained in the Network + Administrator's Guide, available from + <http://www.tldp.org/docs.html#guide>, on its man page: "man + nfs", and in the NFS-HOWTO. + + A superior but less widely used alternative to NFS is provided by + the Coda file system; see "Coda file system support" below. + + If you say Y here, you should have said Y to TCP/IP networking also. + This option would enlarge your kernel by about 27 KB. + + This file system is also available as a module ( = code which can be + inserted in and removed from the running kernel whenever you want). + The module is called nfs.o.

For details, read + <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO, + available from <http://www.tldp.org/docs.html#howto>. + + Note: if you just want your box to act as an SMB *server* and make + files and printing services available to Windows clients (which need + to have a TCP/IP stack), you don't need to say Y here; you can use + the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>) + for that. + + General information about how to connect Linux, Windows machines and + Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>. + + If you want to compile the SMB support as a module ( = code which + can be inserted in and removed from the running kernel whenever you + want), say M here and read <file:Documentation/modules.txt>. The + module will be called smbfs.o. Most people say N, however. + +Use a default NLS +CONFIG_SMB_NLS_DEFAULT + Enabling this will make smbfs use nls translations by default. You + need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls + settings and you need to give the default nls for the SMB server as + CONFIG_SMB_NLS_REMOTE. + + The nls settings can be changed at mount time, if your smbmount + supports that, using the codepage and iocharset parameters. + + smbmount from samba 2.2.0 or later supports this. + +Default Remote NLS Option +CONFIG_SMB_NLS_REMOTE + This setting allows you to specify a default value for which + codepage the server uses. If this field is left blank no + translations will be done by default. The local codepage/charset + default to CONFIG_NLS_DEFAULT. + + The nls settings can be changed at mount time, if your smbmount + supports that, using the codepage and iocharset parameters. + + smbmount from samba 2.2.0 or later supports this. + +Enable Unix Extensions +CONFIG_SMB_UNIX + Enabling this will make smbfs use the CIFS Unix Extensions if + supported by the server. These extensions allows use of unix user + ids, permissions, file modes, symlinks, etc that normally do not + work on smbfs. + + Samba 3.0 servers supports these extensions. + + If you don't know what all this is about, it is safe to say Y. + +Coda file system support (advanced network fs) +CONFIG_CODA_FS + Coda is an advanced network file system, similar to NFS in that it + enables you to mount file systems of a remote server and access them + with regular Unix commands as if they were sitting on your hard + disk. Coda has several advantages over NFS: support for + disconnected operation (e.g. for laptops), read/write server + replication, security model for authentication and encryption, + persistent client caches and write back caching. + + If you say Y here, your Linux box will be able to act as a Coda + *client*. You will need user level code as well, both for the + client and server. Servers are currently user level, i.e. they need + no kernel support. Please read + <file:Documentation/filesystems/coda.txt> and check out the Coda + home page <http://www.coda.cs.cmu.edu/>. + + If you want to compile the coda client support as a module ( = code + which can be inserted in and removed from the running kernel + whenever you want), say M here and read + <file:Documentation/modules.txt>. The module will be called coda.o. + +InterMezzo file system support (replicating fs) +CONFIG_INTERMEZZO_FS + InterMezzo is a networked file system with disconnected operation + and kernel level write back caching. It is most often used for + replicating potentially large trees or keeping laptop/desktop copies + in sync. + + If you say Y or M your kernel or module will provide InterMezzo + support. You will also need a file server daemon, which you can get + from <http://www.inter-mezzo.org/>. + +NCP file system support (to mount NetWare volumes) +CONFIG_NCP_FS + NCP (NetWare Core Protocol) is a protocol that runs over IPX and is + used by Novell NetWare clients to talk to file servers. It is to + IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you + to mount NetWare file server volumes and to access them just like + any other Unix directory. For details, please read the file + <file:Documentation/filesystems/ncpfs.txt> in the kernel source and + the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>. + + You do not have to say Y here if you want your Linux box to act as a + file *server* for Novell NetWare clients. + + General information about how to connect Linux, Windows machines and + Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>. + + If you want to compile this as a module ( = code which can be + inserted in and removed from the running kernel whenever you want), + say M here and read <file:Documentation/modules.txt>. The module + will be called ncpfs.o. Say N unless you are connected to a Novell + network. + +Packet signatures +CONFIG_NCPFS_PACKET_SIGNING + NCP allows packets to be signed for stronger security. If you want + security, say Y. Normal users can leave it off. To be able to use + packet signing you must use ncpfs > 2.0.12. + +Proprietary file locking +CONFIG_NCPFS_IOCTL_LOCKING + Allows locking of records on remote volumes. Say N unless you have + special applications which are able to utilize this locking scheme. + +Clear remove/delete inhibit when needed +CONFIG_NCPFS_STRONG + Allows manipulation of files flagged as Delete or Rename Inhibit. + To use this feature you must mount volumes with the ncpmount + parameter "-s" (ncpfs-2.0.12 and newer). Say Y unless you are not + mounting volumes with -f 444. + +Use NFS namespace if available +CONFIG_NCPFS_NFS_NS + Allows you to utilize NFS namespace on NetWare servers. It brings + you case sensitive filenames. Say Y. You can disable it at + mount-time with the `-N nfs' parameter of ncpmount. + +Use LONG (OS/2) namespace if available +CONFIG_NCPFS_OS2_NS + Allows you to utilize OS2/LONG namespace on NetWare servers. + Filenames in this namespace are limited to 255 characters, they are + case insensitive, and case in names is preserved. Say Y. You can + disable it at mount time with the -N os2 parameter of ncpmount. + +Lowercase DOS filenames on LONG namespace volume +CONFIG_NCPFS_SMALLDOS + If you say Y here, every filename on a NetWare server volume using + the OS2/LONG namespace and created under DOS or on a volume using + DOS namespace will be converted to lowercase characters. + Saying N here will give you these filenames in uppercase. + + This is only a cosmetic option since the OS2/LONG namespace is case + insensitive. The only major reason for this option is backward + compatibility when moving from DOS to OS2/LONG namespace support. + Long filenames (created by Win95) will not be affected. + + This option does not solve the problem that filenames appear + differently under Linux and under Windows, since Windows does an + additional conversions on the client side. You can achieve similar + effects by saying Y to "Allow using of Native Language Support" + below. + +Use Native Language Support +CONFIG_NCPFS_NLS + Allows you to use codepages and I/O charsets for file name + translation between the server file system and input/output. This + may be useful, if you want to access the server with other operating + systems, e.g. Windows 95. See also NLS for more Information. + + To select codepages and I/O charsets use ncpfs-2.2.0.13 or newer. + +Symbolic links and mode permission bits +CONFIG_NCPFS_EXTRAS + This enables the use of symbolic links and an execute permission + bit on NCPFS.

The slave device behaves identical to + a physical terminal; the master device is used by a process to + read data from and write data to the slave, thereby emulating a + terminal. Typical programs for the master side are telnet servers + and xterms. + + Linux has traditionally used the BSD-like names /dev/ptyxx for + masters and /dev/ttyxx for slaves of pseudo terminals. This scheme + has a number of problems. The GNU C library glibc 2.1 and later, + however, supports the Unix98 naming standard: in order to acquire a + pseudo terminal, a process opens /dev/ptmx; the number of the pseudo + terminal is then made available to the process and the pseudo + terminal slave can be accessed as /dev/pts/<number>. What was + traditionally /dev/ttyp2 will then be /dev/pts/2, for example. + + The entries in /dev/pts/ are created on the fly by a virtual + file system; therefore, if you say Y here you should say Y to + "/dev/pts file system for Unix98 PTYs" as well. + + If you want to say Y here, you need to have the C library glibc 2.1 + or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*"). + Read the instructions in <file:Documentation/Changes> pertaining to + pseudo terminals.

Server + machines which support incoming telnet/rlogin/ssh connections and/or + serve several X terminals may want to increase this: every incoming + connection and every xterm uses up one PTY. + + When not in use, each additional set of 256 PTYs occupy + approximately 8 KB of kernel memory on 32-bit architectures. + +Parallel printer support +CONFIG_PRINTER + If you intend to attach a printer to the parallel port of your Linux + box (as opposed to using a serial printer; if the connector at the + printer has 9 or 25 holes ["female"], then it's serial), say Y. + Also read the Printing-HOWTO, available from + <http://www.tldp.org/docs.html#howto>. + + It is possible to share one parallel port among several devices + (e.g. printer and ZIP drive) and it is safe to compile the + corresponding drivers into the kernel.

Note that the file system interface has + changed quite a bit compared to previous versions of ftape. Please + read <file:Documentation/ftape.txt>. + +VFS interface for ftape +CONFIG_ZFTAPE + Normally, you want to say Y or M. DON'T say N here or you + WON'T BE ABLE TO USE YOUR FLOPPY TAPE DRIVE. + + The ftape module itself no longer contains the routines necessary + to interface with the kernel VFS layer (i.e. to actually write data + to and read data from the tape drive). Instead the file system + interface (i.e. the hardware independent part of the driver) has + been moved to a separate module. + + If you say M zftape will be compiled as a runtime loadable + module ( = code which can be inserted in and removed from the + running kernel whenever you want). In this case you should read + <file:Documentation/modules.txt>. The module will be called + zftape.o. + + Regardless of whether you say Y or M here, an additional runtime + loadable module called `zft-compressor.o' which contains code to + support user transparent on-the-fly compression based on Ross + William's lzrw3 algorithm will be produced. If you have enabled the + kernel module loader (i.e. have said Y to "Kernel module loader + support", above) then `zft-compressor.o' will be loaded + automatically by zftape when needed. + + Despite its name, zftape does NOT use compression by default. The + file <file:Documentation/ftape.txt> contains a short description of + the most important changes in the file system interface compared to + previous versions of ftape. The ftape home page + <http://www.instmath.rwth-aachen.de/~heine/ftape/> contains + further information. + + IMPORTANT NOTE: zftape can read archives created by previous + versions of ftape and provide file mark support (i.e. fast skipping + between tape archives) but previous version of ftape will lack file + mark support when reading archives produced by zftape. + +Default block size for zftape +CONFIG_ZFT_DFLT_BLK_SZ + If unsure leave this at its default value, i.e. 10240. Note that + you specify only the default block size here. The block size can be + changed at run time using the MTSETBLK tape operation with the + MTIOCTOP ioctl (i.e. with "mt -f /dev/qft0 setblk #BLKSZ" from the + shell command line). + + The probably most striking difference between zftape and previous + versions of ftape is the fact that all data must be written or read + in multiples of a fixed block size. The block size defaults to + 10240 which is what GNU tar uses. The values for the block size + should be either 1 or multiples of 1024 up to a maximum value of + 63488 (i.e. 62 K). If you specify `1' then zftape's builtin + compression will be disabled. + + Reasonable values are `10240' (GNU tar's default block size), + `5120' (afio's default block size), `32768' (default block size some + backup programs assume for SCSI tape drives) or `1' (no restriction + on block size, but disables builtin compression). + +Number of DMA buffers +CONFIG_FT_NR_BUFFERS + Please leave this at `3' unless you REALLY know what you are doing. + It is not necessary to change this value. Values below 3 make the + proper use of ftape impossible, values greater than 3 are a waste of + memory. You can change the amount of DMA memory used by ftape at + runtime with "mt -f /dev/qft0 setdrvbuffer #NUMBUFFERS". Each buffer + wastes 32 KB of memory. Please note that this memory cannot be + swapped out. + +Enable procfs status report (+2kb) +CONFIG_FT_PROC_FS + Optional. Saying Y will result in creation of a directory + `/proc/ftape' under the /proc file system. The files can be viewed + with your favorite pager (i.e. use "more /proc/ftape/history" or + "less /proc/ftape/history" or simply "cat /proc/ftape/history"). The + file will contain some status information about the inserted + cartridge, the kernel driver, your tape drive, the floppy disk + controller and the error history for the most recent use of the + kernel driver. Saying Y will enlarge the size of the ftape driver + by approximately 2 KB. + + WARNING: When compiling ftape as a module (i.e. saying M to "Floppy + tape drive") it is dangerous to use ftape's /proc file system + interface. Accessing `/proc/ftape' while the module is unloaded will + result in a kernel Oops. This cannot be fixed from inside ftape. + +# Choice: ftdebug +Controlling the amount of debugging output of ftape +CONFIG_FT_NORMAL_DEBUG + This option controls the amount of debugging output the ftape driver + is ABLE to produce; it does not increase or diminish the debugging + level itself. If unsure, leave this at its default setting, + i.e. choose "Normal". + + Ftape can print lots of debugging messages to the system console + resp. kernel log files. Reducing the amount of possible debugging + output reduces the size of the kernel module by some KB, so it might + be a good idea to use "None" for emergency boot floppies. + + If you want to save memory then the following strategy is + recommended: leave this option at its default setting "Normal" until + you know that the driver works as expected, afterwards reconfigure + the kernel, this time specifying "Reduced" or "None" and recompile + and install the kernel as usual. Note that choosing "Excessive" + debugging output does not increase the amount of debugging output + printed to the console but only makes it possible to produce + "Excessive" debugging output. + + Please read <file:Documentation/ftape.txt> for a short description + how to control the amount of debugging output. + +Excessive +CONFIG_FT_FULL_DEBUG + Extremely verbose output for driver debugging purposes. + +Reduced +CONFIG_FT_NO_TRACE + Reduced tape driver debugging output. + +None +CONFIG_FT_NO_TRACE_AT_ALL + Suppress all debugging output from the tape drive. + +# Choice: ftcontroller +The floppy drive controller for ftape +CONFIG_FT_STD_FDC + Only change this setting if you have a special controller.

To do + this, say M here and read <file:Documentation/modules.txt> as well + as <file:Documentation/sound/README.modules>; the module will be + called soundcore.o. + + I'm told that even without a sound card, you can make your computer + say more than an occasional beep, by programming the PC speaker. + Kernel patches and supporting utilities to do that are in the pcsp + package, available at <ftp://ftp.infradead.org/pub/pcsp/>. + +OSS sound modules +CONFIG_SOUND_OSS + OSS is the Open Sound System suite of sound card drivers. They make + sound programming easier since they provide a common API. Say Y or + M here (the module will be called sound.o) if you haven't found a + driver for your sound card above, then pick your driver from the + list below. + +Persistent DMA buffers +CONFIG_SOUND_DMAP + Linux can often have problems allocating DMA buffers for ISA sound + cards on machines with more than 16MB of RAM. This is because ISA + DMA buffers must exist below the 16MB boundary and it is quite + possible that a large enough free block in this region cannot be + found after the machine has been running for a while. If you say Y + here the DMA buffers (64Kb) will be allocated at boot time and kept + until the shutdown. This option is only useful if you said Y to + "OSS sound modules", above. If you said M to "OSS sound modules" + then you can get the persistent DMA buffer functionality by passing + the command-line argument "dmabuf=1" to the sound.o module. + + Say Y unless you have 16MB or less RAM or a PCI sound card. + +Support for Aztech Sound Galaxy (non-PnP) cards +CONFIG_SOUND_SGALAXY + This module initializes the older non Plug and Play sound galaxy + cards from Aztech. It supports the Waverider Pro 32 - 3D and the + Galaxy Washington 16. + + If you compile the driver into the kernel, you have to add + "sgalaxy=<io>,<irq>,<dma>,<dma2>,<sgbase>" to the kernel command + line. + +Support for AD1816(A) based cards +CONFIG_SOUND_AD1816 + Say M here if you have a sound card based on the Analog Devices + AD1816(A) chip. + + If you compile the driver into the kernel, you have to add + "ad1816=<io>,<irq>,<dma>,<dma2>" to the kernel command line. + +Yamaha OPL3-SA1 audio controller +CONFIG_SOUND_OPL3SA1 + Say Y or M if you have a Yamaha OPL3-SA1 sound chip, which is + usually built into motherboards. Read + <file:Documentation/sound/OPL3-SA> for details. + + If you compile the driver into the kernel, you have to add + "opl3sa=<io>,<irq>,<dma>,<dma2>,<mpuio>,<mpuirq>" to the kernel + command line. + +ProAudioSpectrum 16 support +CONFIG_SOUND_PAS + Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio + 16 or Logitech SoundMan 16 sound card. Answer N if you have some + other card made by Media Vision or Logitech since those are not + PAS16 compatible. Please read <file:Documentation/sound/PAS16>. + It is not necessary to add Sound Blaster support separately; it + is included in PAS support. + + If you compile the driver into the kernel, you have to add + "pas2=<io>,<irq>,<dma>,<dma2>,<sbio>,<sbirq>,<sbdma>,<sbdma2> + to the kernel command line. + +Enable PAS16 joystick port +CONFIG_PAS_JOYSTICK + Say Y here to enable the Pro Audio Spectrum 16's auxiliary joystick + port. + +100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support +CONFIG_SOUND_SB + Answer Y if you have an original Sound Blaster card made by Creative + Labs or a 100% hardware compatible clone (like the Thunderboard or + SM Games). For an unknown card you may answer Y if the card claims + to be Sound Blaster-compatible. + + Please read the file <file:Documentation/sound/Soundblaster>. + + You should also say Y here for cards based on the Avance Logic + ALS-007 and ALS-1X0 chips (read <file:Documentation/sound/ALS>) and + for cards based on ESS chips (read + <file:Documentation/sound/ESS1868> and + <file:Documentation/sound/ESS>). If you have an SB AWE 32 or SB AWE + 64, say Y here and also to "AWE32 synth" below and read + <file:Documentation/sound/INSTALL.awe>. If you have an IBM Mwave + card, say Y here and read <file:Documentation/sound/mwave>. + + If you compile the driver into the kernel and don't want to use + isapnp, you have to add "sb=<io>,<irq>,<dma>,<dma2>" to the kernel + command line. + + You can say M here to compile this driver as a module; the module is + called sb.o. + +Gravis Ultrasound support +CONFIG_SOUND_GUS + Say Y here for any type of Gravis Ultrasound card, including the GUS + or GUS MAX. See also <file:Documentation/sound/ultrasound> for more + information on configuring this card with modules. + + If you compile the driver into the kernel, you have to add + "gus=<io>,<irq>,<dma>,<dma2>" to the kernel command line. + +MPU-401 support (NOT for SB16) +CONFIG_SOUND_MPU401 + Be careful with this question. The MPU401 interface is supported by + all sound cards. However, some natively supported cards have their + own driver for MPU401. Enabling this MPU401 option with these cards + will cause a conflict. Also, enabling MPU401 on a system that + doesn't really have a MPU401 could cause some trouble. If your card + was in the list of supported cards, look at the card specific + instructions in the <file:Documentation/sound/README.OSS> file. It + is safe to answer Y if you have a true MPU401 MIDI interface card. + + If you compile the driver into the kernel, you have to add + "mpu401=<io>,<irq>" to the kernel command line. + +6850 UART support +CONFIG_SOUND_UART6850 + This option enables support for MIDI interfaces based on the 6850 + UART chip. This interface is rarely found on sound cards. It's safe + to answer N to this question. + + If you compile the driver into the kernel, you have to add + "uart6850=<io>,<irq>" to the kernel command line. + +PSS (AD1848, ADSP-2115, ESC614) support +CONFIG_SOUND_PSS + Answer Y or M if you have an Orchid SW32, Cardinal DSP16, Beethoven + ADSP-16 or some other card based on the PSS chipset (AD1848 codec + + ADSP-2115 DSP chip + Echo ESC614 ASIC CHIP). For more information on + how to compile it into the kernel or as a module see the file + <file:Documentation/sound/PSS>. + + If you compile the driver into the kernel, you have to add + "pss=<io>,<mssio>,<mssirq>,<mssdma>,<mpuio>,<mpuirq>" to the kernel + command line. + +Enable PSS mixer (Beethoven ADSP-16 and other compatible) +CONFIG_PSS_MIXER + Answer Y for Beethoven ADSP-16. You may try to say Y also for other + cards if they have master volume, bass, treble, and you can't + control it under Linux. If you answer N for Beethoven ADSP-16, you + can't control master volume, bass, treble and synth volume. + + If you said M to "PSS support" above, you may enable or disable this + PSS mixer with the module parameter pss_mixer. For more information + see the file <file:Documentation/sound/PSS>. + +Have DSPxxx.LD firmware file +CONFIG_PSS_HAVE_BOOT + If you have the DSPxxx.LD file or SYNTH.LD file for you card, say Y + to include this file.

These chips are + quite common so it's possible that many no-name cards have one of + them. In addition the MAD16 chip is used in some cards made by known + manufacturers such as Turtle Beach (Tropez), Reveal (some models) + and Diamond (latest ones). Note however that the Tropez sound cards + have their own driver; if you have one of those, say N here and Y or + M to "Full support for Turtle Beach WaveFront", below. + + If you compile the driver into the kernel, you have to add + "mad16=<io>,<irq>,<dma>,<dma2>,<mpuio>,<mpuirq>" to the + kernel command line. + + See also <file:Documentation/sound/Opti> and + <file:Documentation/sound/MAD16> for more information on setting + these cards up as modules. + +Full support for Turtle Beach WaveFront (Tropez Plus, Tropez, Maui) synth/sound cards +CONFIG_SOUND_WAVEFRONT + Answer Y or M if you have a Tropez Plus, Tropez or Maui sound card + and read the files <file:Documentation/sound/Wavefront> and + <file:Documentation/sound/Tropez+>. + +Support MIDI in older MAD16 based cards (requires SB) +CONFIG_MAD16_OLDCARD + Answer Y (or M) if you have an older card based on the C928 or + Mozart chipset and you want to have MIDI support.

There is an official Q40 home page at + <http://www.q40.de/>. This option enables support for the Q40 and + Q60. Select your CPU below. For 68LC060 don't forget to enable FPU + emulation. + +Q40/Q60 IDE interface support +CONFIG_BLK_DEV_Q40IDE + Enable the on-board IDE controller in the Q40/Q60. This should + normally be on; disable it only if you are running a custom hard + drive subsystem through an expansion card. + +Sun 3 support +CONFIG_SUN3 + This option enables support for the Sun 3 series of workstations. + Note that if this option is enabled, support for all other m68k + platforms above must be disabled in order to produce a working + kernel. + + Also, you will want to enable 68020 support below, and disable + all other CPU types.

Otherwise, say N. + +Math emulation support +CONFIG_M68KFPU_EMU + At some point in the future, this will cause floating-point math + instructions to be emulated by the kernel on machines that lack a + floating-point math coprocessor. Thrill-seekers and chronically + sleep-deprived psychotic hacker types can say Y now, everyone else + should probably wait a while. + +Math emulation only kernel +CONFIG_M68KFPU_EMU_ONLY + This option prevents any floating-point instructions from being + compiled into the kernel, thereby the kernel doesn't save any + floating point context anymore during task switches, so this + kernel will only be usable on machines without a floating-point + math coprocessor. This makes the kernel a bit faster as no tests + needs to be executed whether a floating-point instruction in the + kernel should be executed or not. + +Math emulation extra precision +CONFIG_M68KFPU_EMU_EXTRAPREC + The fpu uses normally a few bit more during calculations for + correct rounding, the emulator can (often) do the same but this + extra calculation can cost quite some time, so you can disable + it here. The emulator will then "only" calculate with a 64 bit + mantissa and round slightly incorrect, what is more then enough + for normal usage. + +Advanced configuration options +CONFIG_ADVANCED + This gives you access to some advanced options for the CPU. The + defaults should be fine for most users, but these options may make + it possible for you to improve performance somewhat if you know what + you are doing. + + Note that the answer to this question won't directly affect the + kernel: saying N will just cause the configurator to skip all + the questions about these options. + + Most users should say N to this question. + +Use one physical chunk of memory only +CONFIG_SINGLE_MEMORY_CHUNK + Ignore all but the first contiguous chunk of physical memory for VM + purposes. This will save a few bytes kernel size and may speed up + some operations. Say N if not sure. + +Use read-modify-write instructions +CONFIG_RMW_INSNS + This allows to use certain instructions that work with indivisible + read-modify-write bus cycles. While this is faster than the + workaround of disabling interrupts, it can conflict with DMA + ( = direct memory access) on many Amiga systems, and it is also said + to destabilize other machines. It is very likely that this will + cause serious problems on any Amiga or Atari Medusa if set. The only + configuration where it should work are 68030-based Ataris, where it + apparently improves performance. But you've been warned! Unless you + really know what you are doing, say N. Try Y only if you're quite + adventurous. + +Amiga Zorro (AutoConfig) bus support +CONFIG_ZORRO + This enables support for the Zorro bus in the Amiga. If you have + expansion cards in your Amiga that conform to the Amiga + AutoConfig(tm) specification, say Y, otherwise N. Note that even + expansion cards that do not fit in the Zorro slots but fit in e.g. + the CPU slot may fall in this category, so you have to say Y to let + Linux use these. + +Zorro device name database +CONFIG_ZORRO_NAMES + By default, the kernel contains a database of all known Zorro device + names to make the information in /proc/iomem comprehensible to the + user. This database increases the size of the kernel image by about + 15KB, but it gets freed after the system boots up, so it doesn't + take up kernel memory. Anyway, if you are building an installation + floppy or kernel for an embedded system where kernel image size + really matters, you can disable this feature and you'll get device + ID numbers instead of names. + + When in doubt, say Y. + +Amiga 1200/600 PCMCIA support +CONFIG_AMIGA_PCMCIA + Include support in the kernel for pcmcia on Amiga 1200 and Amiga + 600. If you intend to use pcmcia cards say Y; otherwise say N. + +Hisoft Whippet PCMCIA serial support +CONFIG_WHIPPET_SERIAL + HiSoft has a web page at <http://www.hisoft.co.uk/>, but there + is no listing for the Whippet in their Amiga section. + +Amiga Zorro II ramdisk support +CONFIG_AMIGA_Z2RAM + This enables support for using Chip RAM and Zorro II RAM as a + ramdisk or as a swap partition. Say Y if you want to include this + driver in the kernel. This driver is also available as a module + ( = code which can be inserted in and removed from the running + kernel whenever you want). The module is called z2ram.o. If you want + to compile it as a module, say M here and read + <file:Documentation/modules.txt>. + +Support for ST-RAM as swap space +CONFIG_STRAM_SWAP + Some Atari 68k machines (including the 520STF and 1020STE) divide + their addressable memory into ST and TT sections. The TT section + (up to 512MB) is the main memory; the ST section (up to 4MB) is + accessible to the built-in graphics board, runs slower, and is + present mainly for backward compatibility with older machines. + + This enables support for using (parts of) ST-RAM as swap space, + instead of as normal system memory. This can first enhance system + performance if you have lots of alternate RAM (compared to the size + of ST-RAM), because executable code always will reside in faster + memory. ST-RAM will remain as ultra-fast swap space. On the other + hand, it allows much improved dynamic allocations of ST-RAM buffers + for device driver modules (e.g. floppy, ACSI, SLM printer, DMA + sound). The probability that such allocations at module load time + fail is drastically reduced. + +ST-RAM statistics in /proc +CONFIG_STRAM_PROC + Say Y here to report ST-RAM usage statistics in /proc/stram. See + the help for CONFIG_STRAM_SWAP for discussion of ST-RAM and its + uses. + +Atari ACSI support +CONFIG_ATARI_ACSI + This enables support for the Atari ACSI interface. The driver + supports hard disks and CD-ROMs, which have 512-byte sectors, or can + be switched to that mode. Due to the ACSI command format, only disks + up to 1 GB are supported. Special support for certain ACSI to SCSI + adapters, which could relax that, isn't included yet. The ACSI + driver is also the basis for certain other drivers for devices + attached to the ACSI bus: Atari SLM laser printer, BioNet-100 + Ethernet, and PAMsNet Ethernet. If you want to use one of these + devices, you need ACSI support, too. + + This driver is also available as a module ( = code which can be + inserted in and removed from the running kernel whenever you want). + The module will be called acsi.o. + +Probe all LUNs on each ACSI device +CONFIG_ACSI_MULTI_LUN + If you have a ACSI device that supports more than one LUN (Logical + Unit Number), e.g. a CD jukebox, you should say Y here so that all + will be found by the ACSI driver. An ACSI device with multiple LUNs + acts logically like multiple ACSI devices.

Otherwise, say N. This driver is also available as + a module ( = code which can be inserted in and removed from the + running kernel whenever you want). The module will be called + acsi_slm.o.

This is handy if you want to use gdb or + addr2line to debug the kernel. It has no impact on the in-memory + footprint of the running kernel but it can increase the amount of + time and disk space needed for compilation of the kernel. If in + doubt say N. + +Kernel low-level debugging functions +CONFIG_DEBUG_LL + Say Y here to include definitions of printascii, printchar, printhex + in the kernel. This is helpful if you are debugging code that + executes before the console is initialized. + +Kernel low-level debugging messages via footbridge serial port +CONFIG_DEBUG_DC21285_PORT + Say Y here if you want the debug print routines to direct their + output to the serial port in the DC21285 (Footbridge).

On no account + allow random users access to this device. :-) + + This driver is also available as a module ( = code which can be + inserted in and removed from the running kernel whenever you want). + The module will be called nwflash.o. If you want to compile it as a + module, say M here and read <file:Documentation/modules.txt>. + + If you're not sure, say N. + +SRM environment variables in procfs +CONFIG_SRM_ENV + If you enable this option, a subdirectory inside /proc called + /proc/srm_environment will give you access to the all important + SRM environment variables (those which have a name) and also + to all others (by their internal number). + + SRM is something like a BIOS for Alpha machines. There are some + other such BIOSes, like AlphaBIOS, which this driver cannot + support (hey, that's not SRM!). + + Despite the fact that this driver doesn't work on all Alphas (but + only on those which have SRM as their firmware), it's save to + build it even if your particular machine doesn't know about SRM + (or if you intend to compile a generic kernel). It will simply + not create those subdirectory in /proc (and give you some warning, + of course). + + This driver is also available as a module and will be called + srm_env.o then. + +Footbridge internal watchdog +CONFIG_21285_WATCHDOG + The Intel Footbridge chip contains a builtin watchdog circuit. Say Y + here if you wish to use this. Alternatively say M to compile the + driver as a module, which will be called wdt285.o. + + This driver does not work on all machines. In particular, early CATS + boards have hardware problems that will cause the machine to simply + lock up if the watchdog fires. + + "If in doubt, leave it out" - say N. + +NetWinder WB83C977 watchdog +CONFIG_977_WATCHDOG + Say Y here to include support for the WB977 watchdog included in + NetWinder machines. Alternatively say M to compile the driver as + a module, which will be called wdt977.o. + + Not sure? It's safe to say N. + +IrDA subsystem support +CONFIG_IRDA + Say Y here if you want to build support for the IrDA (TM) protocols. + The Infrared Data Associations (tm) specifies standards for wireless + infrared communication and is supported by most laptops and PDA's. + + To use Linux support for the IrDA (tm) protocols, you will also need + some user-space utilities like irattach. For more information, see + the file <file:Documentation/networking/irda.txt>. You also want to + read the IR-HOWTO, available at + <http://www.tldp.org/docs.html#howto>. + + If you want to exchange bits of data (vCal, vCard) with a PDA, you + will need to install some OBEX application, such as OpenObex : + <http://sourceforge.net/projects/openobex/> + + This support is also available as a module called irda.o. If you + want to compile it as a module, say M here and read + <file:Documentation/modules.txt>. + +Ultra (connectionless) protocol +CONFIG_IRDA_ULTRA + Say Y here to support the connectionless Ultra IRDA protocol. + Ultra allows to exchange data over IrDA with really simple devices + (watch, beacon) without the overhead of the IrDA protocol (no handshaking, + no management frames, simple fixed header). + Ultra is available as a special socket : socket(AF_IRDA, SOCK_DGRAM, 1); + +IrDA cache last LSAP +CONFIG_IRDA_CACHE_LAST_LSAP + Say Y here if you want IrLMP to cache the last LSAP used. This + makes sense since most frames will be sent/received on the same + connection. Enabling this option will save a hash-lookup per frame. + + If unsure, say Y. + +IrDA Fast RRs +CONFIG_IRDA_FAST_RR + Say Y here is you want IrLAP to send fast RR (Receive Ready) frames + when acting as a primary station. + Disabling this option will make latency over IrDA very bad. Enabling + this option will make the IrDA stack send more packet than strictly + necessary, thus reduce your battery life (but not that much). + + Fast RR will make IrLAP send out a RR frame immediately when + receiving a frame if its own transmit queue is currently empty. This + will give a lot of speed improvement when receiving much data since + the secondary station will not have to wait the max. turn around + time (usually 500ms) before it is allowed to transmit the next time. + If the transmit queue of the secondary is also empty, the primary will + start backing-off before sending another RR frame, waiting longer + each time until the back-off reaches the max. turn around time. + This back-off increase in controlled via + /proc/sys/net/irda/fast_poll_increase + + If unsure, say Y. + +IrDA debugging information +CONFIG_IRDA_DEBUG + Say Y here if you want the IrDA subsystem to write debug information + to your syslog. You can change the debug level in + /proc/sys/net/irda/debug . + When this option is enabled, the IrDA also perform many extra internal + verifications which will usually prevent the kernel to crash in case of + bugs. + + If unsure, say Y (since it makes it easier to find the bugs). + +IrLAN protocol +CONFIG_IRLAN + Say Y here if you want to build support for the IrLAN protocol. If + you want to compile it as a module (irlan.o), say M here and read + <file:Documentation/modules.txt>. IrLAN emulates an Ethernet and + makes it possible to put up a wireless LAN using infrared beams. + + The IrLAN protocol can be used to talk with infrared access points + like the HP NetbeamIR, or the ESI JetEye NET. You can also connect + to another Linux machine running the IrLAN protocol for ad-hoc + networking! + +IrNET protocol +CONFIG_IRNET + Say Y here if you want to build support for the IrNET protocol. If + you want to compile it as a module (irnet.o), say M here and read + <file:Documentation/modules.txt>. IrNET is a PPP driver, so you + will also need a working PPP subsystem (driver, daemon and + config)... + + IrNET is an alternate way to transfer TCP/IP traffic over IrDA. It + uses synchronous PPP over a set of point to point IrDA sockets. You + can use it between Linux machine or with W2k. + +IrCOMM protocol +CONFIG_IRCOMM + Say Y here if you want to build support for the IrCOMM protocol. If + you want to compile it as a module (you will get ircomm.o and + ircomm-tty.o), say M here and read <file:Documentation/modules.txt>. + IrCOMM implements serial port emulation, and makes it possible to + use all existing applications that understands TTY's with an + infrared link. Thus you should be able to use application like PPP, + minicom and others. Enabling this option will create two modules + called ircomm and ircomm_tty. + +IrTTY IrDA Device Driver +CONFIG_IRTTY_SIR + Say Y here if you want to build support for the IrTTY line + discipline. If you want to compile it as a module (irtty.o), say M + here and read <file:Documentation/modules.txt>. IrTTY makes it + possible to use Linux's own serial driver for all IrDA ports that + are 16550 compatible. Most IrDA chips are 16550 compatible so you + should probably say Y to this option. Using IrTTY will however + limit the speed of the connection to 115200 bps (IrDA SIR mode). + + If unsure, say Y. + +IrPORT IrDA serial driver +CONFIG_IRPORT_SIR + Say Y here if you want to build support for the IrPORT IrDA device + driver. If you want to compile it as a module (irport.o), say M here + and read <file:Documentation/modules.txt>. IrPORT can be used + instead of IrTTY and sometimes this can be better. One example is + if your IrDA port does not have echo-canceling, which will work OK + with IrPORT since this driver is working in half-duplex mode only. + You don't need to use irattach with IrPORT, but you just insert it + the same way as FIR drivers (insmod irport io=0x3e8 irq=11). Notice + that IrPORT is a SIR device driver which means that speed is limited + to 115200 bps. + + If unsure, say Y. + +USB IrDA FIR dongle Device Driver +CONFIG_USB_IRDA + Say Y here if you want to build support for the USB IrDA FIR Dongle + device driver. If you want to compile it as a module (irda-usb.o), + say M here and read <file:Documentation/modules.txt>. IrDA-USB + support the various IrDA USB dongles available and most of their + peculiarities. Those dongles plug in the USB port of your computer, + are plug and play, and support SIR and FIR (4Mbps) speeds. On the + other hand, those dongles tend to be less efficient than a FIR + chipset. + + Please note that the driver is still experimental. And of course, + you will need both USB and IrDA support in your kernel... + +Datafab MDCFE-B Compact Flash Reader support +CONFIG_USB_STORAGE_DATAFAB + This option enables a sub-driver of the USB Mass Storage driver.
