Ampro Littleboard problems..

Well, I made the assumption that since my rev 0.00 (not really, but I ordered
the boards before any had been made) EPROM gives a prompt, they all did.
Perhaps that isn't the case. If it's SCSI capable, it's a year or more newer
than my EPROM. They didn't have a hard disk back when I bought these. It has
to find that there's no disk drive, however, else it simply tries to boot from
that. After a timeout of maybe a minute, it defaults to the prompt screen,
which is a menu.
