Actually, I upgraded to 2.0.30 (and even installed the pre-7 patch for
2.0.31). Now the card is recognized, though I'm having some other
problems... I have a UMAX scanner, and if the scanner cable is attached to
the external port (even with the scanner turned off), the kernel panics
during scsi initialization, with a message like:
"Error: something reset the scsi bus"
If I disconnect the cable and reboot the system comes up okay.
(Next time I'm at my PC I'll write down the exact panic message I got and
repost it.)
I tried changing my lilo.conf parameter from
"append aic7xxx=ultra"
to
"append aic7xxx=no_reset,ultra"
(on a suggestion I read) but that made no difference.
This kind of defeats the purpose of my getting the card to begin with,
so I can use the scanner with Linux. If I reconnect the scanner after
bootup and run the umax driver utility, it doesn't find the scanner.
(That might be perfectly normal, I'm new at using SCSI...)
I looked at the SCSISelect boot utility that comes up before the OS, but
didn't see anything useful to try to tweak. At least some progress has
been made - my card is recognized by Linux. Now if only I can get the
scanner to work with it...
If anyone has used this type of card with a scanner or has any clue what
might be going wrong, I'd appreciate the help.
Thanks,
Rob
