Actually, when you boot from CD-ROM, you are really booting from the
first floppy drive: for bootable "EL-TORITO" CD-ROMs, the motherboard's
BIOS will make the specified boot image, present on the CD-ROM, look
to the BIOS just like the first floppy disk drive.
You may have some luck with "boot -C" (cd-rom). I've never really tried
it. Also checkout the "boot -a" (ask-root) option. You can force these
options to ALWAYS be active by creating a "/boot.config" file containing
your boot-line options, like "0:fd(0,a)/kernel -C".
For the release CD-ROM images, the kernel is compiled with the "MFS_ROOT"
option, and a special program, release/write_mfs_in_kernel.c, is used to
put the root filesystem image into the kernel. With the new forth-based
boot loader, this is no longer necessary (I've done away with it in our
product based on FreeBSD)- you can pre-load the MFS into a "variable",
and the kernel will detect it/use it when it boots.
To build a custom boot floppy image, you should be playing with the
src/release/Makefile and friends. It's kinda tricky in there.
As someone else stated, "/stand/sysinstall" is used as the "init"
program on the release floppies (see src/sys/kern/init_main.c). You want
to use a standard "init". Stick "init" in your boot_crunch.conf file for
your boot floppy image.
Good luck!
