The code in int13_load_eltorito() is intended to allow iPXE to boot from one
of its own SAN drives. The fact that "sanboot --drive XX" can be (ab)used to
boot from a local disk is just an unofficial side benefit.
One possible hackish workaround for this particular scenario would be to SAN-
boot from an ISO which matches the local CD-ROM. The SAN boot would provide
access via INT 13, and the loaded OS would find the (identical) local CD-ROM
after starting the kernel.
Unless I'm missing something, it's probably a better idea to just use wimboot.
