The option rom on it's own won't do much good. LB itself doesn't care
about it and can't use the INT 13h hooks that the option rom installs.
(Plus they are only installed in the emulator, so payloads can't use
them either.)

Depending on the payload, you may not need to care about the option
rom however. Ideally the Linux driver does not require the option
rom to have run to drive the controller.

Anyway, to boot a system on a SCSI disk you will need room for a
Linux kernel in flash. (This is called LAB, suggest to use the LB
companion buildrom to create the rom image.)
