Well,

  I have grub booting from a CD-ROM using an Eltorito image.  Once I had the
  boot floppy setup the way I wanted it (include the grub bootloader)  I
  used mkisofs with the -b option to create the image.  I then burned the
  image to a CDR.

  As long as your CDROM drive supports eltorito CDs (most do)  then you
  should be fine.

  Hope this helps,

  Regards,

    Gerry
