First let me apologize for butting in like this - I get hackers via the digest, so its tough to reply to the right people. I think its useful to note the principle of a bootable CD. You don't really boot the CD. (No really) What you are doing is loading an image of a floppy into RAM, the BIOS then treats this as a ram disk and boots it. This has some interesting ramifications. Its possible to boot pretty much anything that can be put on a floppy - it may even be unable to read the CDROM itself. Also, there may be an issue with the size you choose. My laptop doesn't know about 2.88M disks, so the later BSD cdroms don't boot for me - I have to use 2 floppies. For testing, I'd use a real live floppy, then when I like what I get, I'd dd it into a file and put that on my CDROM, setting the boot image (and don't forget to set the boot catalog name), and burning it. I've used this technique to allow dual booting on my NT box at work - just make a DOS 6 floppy, with a cdrom driver, and put the stuff I wanted to run on the disk (in this case, loadlin + a linux kernel.)
