I think you misread his message, Jim. What he was saying was that in
addition to not booting on the CP/M disks and getting the error message,
he also got the message with a DOS disk, with no disk, and even with the
drive door open. I played with the Osbourne Executive yesterday.
I can't get it to boot.
All it says is "boot error". It says the same thing with no disks in it,
MS DOS disks in it and with the door open so the message doesn't tell me
anything.
Well... from the description above, the first thing that comes to mind is
that the 'Executive', like all of the Osborne machines is a CP/M machine,
and will likely never run any form of MicroSquish DOS... B^}
In more general terms, the message indicates that the unit is unable to
read the boot sector(s), but without a proper set of diskettes it will be
difficult to troubleshoot reliabily... With all of those failure modes, it does not seem
likely to me that it is
a drive problem.
Yep... and the base machine won't give much more of an indication. The
Osbornes tended to think in a go/no-go mode, so the one 'catch-all' error
message is about all you would ever see.
I believe that the 'Exec used a WD1793 series floppy controller chip, so
the controller circuitry should be fairly straight forward.
