I too have an Adaptec 2940-W and am having problems (unable to boot).
I have a 2940-WIDE, not 2940, Pentium 90, PCI.
Q1: Is the 2940-WIDE supported at all?
I've read through the SCSI-HOWTO, PCI-HOWTO, Hardware-HOWTO and the
aic7xxx driver source, and there isn't a clear answer.
Q2: The PCI-HOWTO says:
o The Buslogic BT956W will do WIDE SCSI with the Linux drivers
(although you can't use targets 8-15), the Adaptec 2940W (with one
line patch to the 2940 driver) won't, nor will the NCR53c820 and
NCR53c825.
What's the one line patch? I read through aic7xxx.c from 1.3.36 and
didn't find anything obvious.
Q3: Although I have the 2940-WIDE, my devices (disk and cd) are both
regular (narrow, 8-bit) scsi. For now, I don't need to run the WIDE
channels and I'd be satisfied to run the 2940-WIDE with regular devices.
Is this possible?
I've tried compiling 1.3.36 with the 274x/284x/2940 option.
I've checked the bios, IRQ conflicts, termination etc.
But all I get is "kernel panic" while trying to boot.
I'm borrowing an Adaptec 1522, so I can get into my machine, just not
with the 2940-WIDE. If it helps, I can certainly reinstall the 2940-W
and copy down the error messages.
Thanks,
