Good. Did you need to modify GRUB itself, or just make a mistake in
your configuration file?

See the file TODO. I've written this:
* Add CDROM-chainloading support. It would be enough to support only
BIOSes which have bootable-CDROM support (so you may use the "Bootable
CDROM" BIOS calls). It is not trivial to support BIOSes without the
capability to boot CDROM.
Unlike a floppy, it is not trivial to chain-load a CD-ROM. If you have
a relatively newer BIOS, you can use BIOS calls which are documented
in a specification available from Phoenix (or the Ralf Brown's
Interrupt List). Otherwise, you need to implement a CD-ROM driver and
emulate the El Trito specification. Perhaps many people want the
latter, since older BIOSes don't support CD-ROM booting methods, while
in newer BIOSes, you can just configure your BIOS setup program to
boot from a CD-ROM. If you are interested in either/both of these,
please consider contributing to the GRUB development. I always welcome
any volunteers. :)
