I'm fairly sure it applies to both. The only difference is the location of
the code that boots from CD--system BIOS (for IDE) or expansion-card BIOS
(SCSI). There's some additional information (a boot image, for instance)
that gets written to a CD to make it bootable. This can be located outside
the ISO-9660 filesystem, though some mastering software makes the boot image
visible (more than likely by copying it into the filesystem as well).

I don't even think you can connect an IDE CD-ROM. (You might be able to
plug it in to one of the IDE controllers that now exist, but I don't think
you can do anything useful with it yet.)
