El-Torito (ref: www.phoenix.com/products/specs-cdrom.pdf or others)
is really just a floppy boot image of either 1.44M or 2.88M.
That is why the boot-disk images are EXACTLY 1.44M or 2.88M in
size, so they can just be copied to the boot1 area, and
used "as-is" to make a CD/ROM boot.
You may want to look at the debian-cd boot code from the
CVS sources ( in tools/boot/potato/boot-i386 ) and see
if you can hack it to support multiple images on the same CD.
