No, it is not.  A CD uses a very different boot protocol, and would
require MEMDISK to simulate an El Torito BIOS, which it doesn't; it
simulates a floppy/hard disk BIOS.  It would be possible to write an El
Torito BIOS for the CD, but it probably would still be somewhat
pointless, since most OSes expect to be able to talk directly to a SCSI
or ATAPI controller to talk to the CD.
