I don't think I explained what I want well enough.

I have a computer, with Corel Linux on it (don't laugh). I want to run Koppix Linux on it, but I can't because the BIOS will not boot from a CD-ROM. For the Corel Linux install we had a floppy disk, which told the computer to use the CD to run (and thereofre install). I am looking for something to do this.

Now you might have already told me that what I need is SMB, but from what I understand this boots multiple operating systems (am I right?). I'm not really interested in this. I just want to boot Knoppix.

Does this clarify things or is this how you understood it before? Have I got it completely wrong?
