I have dug out an old SCSI hard drive from 1997 that may have some
interesting stuff, most especially the source
code for the SGI Iris flight sim demo. I have a Linux system with an
Adaptec 2940 (aic7880) that has two
connectors on it. It SEEMS from some probing that the 50-pin IDC
connector on the top of the board is
single-ended SCSI (it seems to have mostly grounds on one row of pins).
Same for the drive, which is a Quantum
ProDrive LPS. The drive spins up and does some seeking right after
power-on, so it sounds like it is
working. But, I can't seem to find that the drive is being recognized
by the aic7xxx driver.
So, looking at /proc/scsi/aic7xxx/## I see the device addresses all show
just the negotiation settings,
and /proc/scsi/scsi just shows my SATA devices but not the real SCSI ones.
I have the right cable to plug my old HP scanner into the mounting plate
Honda connector, and it shows up
fine. I could try getting a Honda to IDC-50 cable, but I thought the
IDC50 connector on the board edge OUGHT to
work.
Does anybody have any suggestions on what to try?
Thanks,
Jon
The Adaptec SCSI cards have a firmware diagnostic utility on them as
well. IIRC, a <Ctrl-A> keypress at the appropriate time during boot-up
of the peecee will start the utility, which allows for setting
controller options as well as running some drive tests or a low-leevel
format.
