SCSI Interface ID Situations

During the search for an operating system phase of the boot process, the Boot ROM
looks for an SCSI interface by checking only the least significant 3 binary bits of each
interface select code set to 111. This means any interface whose select code is 7,15, 23,
or 31 is accessed as if they were an SCSI interface.
