 If you have problems booting Xen, there are a number of boot parameters 
 that may be able to help diagnose problems:
 
- noacpi   	turn acpi probing off, which may confuse Xen on some chipsets
- watchdog	enable NMI watchdog which can report certain failures
- nosmp		disable SMP support
- noht		disable Hyperthreading
- ifname=ethXX	select which Ethernet interface to use if you have multiple
- ifname=dummy	don't use any network interface
- ser_baud=xxx	set serial line baud rate for console 
- dom0_mem=xxx 	set the initial amount of memory for domain0. Xen will also
-		  reserve some memory fr itself too. 
+ ignorebiostables Disable parsing of BIOS-supplied tables. This is needed
+                  for some very unsupported chipsets (eg. nforce2). If you
+                  specify this option then ACPI tables are also ignored, and
+                  SMP suppirt is disabled.
+
+ nosmp		  Disable SMP support.
+                  This option is implied by 'ignorebiostables'.
