The way bootable CD-ROMs work is to embed a floppy-disk image, and have a
"boot catalog" file point to it. The machine's BIOS does some trickery to
redirect the floppy drive to the image from the CD-ROM, then execute it.

Once you've copied all of the files to a Linux partition, you may be able
to install lilo (or your boot loader of choice) and point it to that floppy
disk image as though it were a Linux kernel image (chances are, it is 
actually a Linux kernel image).

You'll also have to set the boot loader options to use your new partition
(instead of the CD-ROM) as the root filesystem.
