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. -- -=] Ford [=- "The number of Unix installations (In Real Life: Mike Ditto) has grown to 10, with more expected." ford@kenobi.cts.com - The Unix Programmer's Manual, ...!sdcsvax!crash!elgar!ford 2nd Edition, June, 1972. ditto@cbmvax.commodore.com
