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.
