Huh?

1. firmware reads CD-ROM (therefore must have a driver)
2. firmware demands MacOS code
3. firmware executes MacOS code ???
4. firmware loads the OS

Um, OK... as long as step 3 doesn't seriously happen, one could
fake out the firmware with a dummy MacOS driver. I wouldn't
expect Apple to have PGP signed these drivers.

Something like this maybe, in whatever binary format Apple used:


        .globl driver_init  /* damn firmware wants this */
driver_init:
        blr
