Actually, it's just the boot code that's in the ROM, not an actual
Unix device driver, but the effect is the same.  The ROM knows how to
autoboot Unix from floppy and 2090 SCSI.  I think it can also use ST-506,
although I've never actually tried it.

Someday, Unix might use the normal Exec autoboot facility, which would
mean that 2090's would no longer work, but any autoboot devices would.
