Mark,
First, I switched my '040s between my 2 A2000s. Both boards ran fine and
mounted all HD partitions. So, at this point I knew that both boards were
OK and the problem was elsewhere.
Second, on the malfunctioning A2000, I configured the '040 so that no HD
was connected, and I booted from a floppy. Everything came up fine there,
too. This made me think that the one A2000 wasn't having trouble "talking"
with the '040 in the CPU slot.
Third, I exchanged the cable-to-DB25 connector between both computers and
discovered that neither would boot-up with the faulty ribbon cable
connector. Thus, the problem was isolated.
Purchasing a 50-pin SCSI cable and installing the HD internally (connected
to the 50-pin internal SCSI connector on the '040) solved the problem.
Now, I'd like to find a way to replace the DB25 connector so I can back up
this HD with my SCSI tape drive (which is usually connected to my other
A2000).
