In my kernel the default root device is 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!

No, sysinstall is THE custom init. Yes, you'd have to replace it with your own init, if you really want to. You can take a look at src/release/picobsd/tinyware/oinit. Or, you can take a look at scripting abilities in sysinstall, if they are enough for your needs. > Someone correct me if I'm talking out of my a.out ;-) I thought you were an elf...

Doesn't the boot.flp actually use sysinstall and a custom init process? Therefore, you'd have to replace sysinstall with an init process of some sort...

Check the kernel config. You may need to build a new GENERIC kernel. Also you'd check for any rc* or /etc/fstab entries that mount the floppy as the root fs.
