- * General Desription:
- *
- * The user interface supports commands for BOOTP, RARP, and TFTP.
- * Also, we support ARP internally. Depending on available data,
- * these interact as follows:
- *
- * BOOTP:
- *
- * Prerequisites: - own ethernet address
- * We want: - own IP address
- * - TFTP server IP address
- * - name of bootfile
- * Next step: ARP
- *
- * RARP:
- *
- * Prerequisites: - own ethernet address
- * We want: - own IP address
- * - TFTP server IP address
- * Next step: ARP
- *
- * ARP:
- *
- * Prerequisites: - own ethernet address
- * - own IP address
- * - TFTP server IP address
- * We want: - TFTP server ethernet address
- * Next step: TFTP
- *
- * DHCP:
- *
- * Prerequisites: - own ethernet address
- * We want: - IP, Netmask, ServerIP, Gateway IP
- * - bootfilename, lease time
- * Next step: - TFTP
- *
- * TFTP:
- *
- * Prerequisites: - own ethernet address
- * - own IP address
- * - TFTP server IP address
- * - TFTP server ethernet address
- * - name of bootfile (if unknown, we use a default name
- * derived from our own IP address)
- * We want: - load the boot file
- * Next step: none
