word:~>cat /boot.help
Usage: bios_drive:interface(unit,partition)kernel_name options
bios_drive 0, 1, ...
interface fd, wd or sd
unit 0, 1, ...
partition a, c, ...
kernel_name name of kernel, or ? for list of files in root directory
options -a (ask name) -C (cdrom) -c (userconfig) -D (dual consoles)
-d (debug early) -g (gdb) -h (serial console) -P (probe kbd)
-r (default root) -s (single user) -v (verbose)
Examples:
1:sd(0,a)mykernel boot `mykernel' on the first SCSI drive when one IDE
drive is present
1:wd(2,a) boot from the second (secondary master) IDE drive
1:sd(0,a)? list the files in the root directory on the specified
drive/unit/partition, and set the default bios_drive,
interface, unit and partition
-cv boot with the defaults, then run UserConfig to modify
hardware parameters (c), and print verbose messages (v)
You will find it in /sys/i386/boot/biosboot/boot.help; it probably
belongs in /usr/mdec as well. You can replace it with your own text if
you prefer; this being why it is in a file (aside from the space
saving).
