Hi,
Please forgive me if this isn't the correct forum for this question, I just
joined the list and didn't see anything about a FAQ in the greeting message
from the list server.
I just purchased an Adaptec 1522A SCSI controller and a Yamaha 4416CDR.
Despite all my efforts to make these work in linux, I can't. The controller
is recognized at bootup, but the CD isn't. I've tried various settings on
the card with no luck. I figured it was a cabling/termination problem until
W95 saw the drive right away (I never told it about the CD but it accessed
it right away) and could read from it with no problems. To me this
suggests that the hardware is working fine. I've read through the
Hardware-Howto, the old SCSI-Howto, poked through drivers/scsi/aha152x.c,
Adaptec's web site, and even tried deja-news to find information on this
problem and have come up empty.
The one idea I *do* have, that I'm not sure of, is upgrading the BIOS in the
SCSI card. On bootup it says it's BIOS revision 1.2L and adaptec's web site
has revision 1.4. I'm not sure I want to try that. The BIOS message that
the card displays shows no information about attached devices, even though
I have the jumper settings for displaying "SCSI device information".
If somebody could give me some help here figuring out what's wrong, I would
VERY much appreciate it. I've not used SCSI much, and don't know what else
to try. You should find all the useful information (that I can find) that
the system provides below. I specifically don't know how to interpret the
information in "/proc/scsi/aha152x/0" (listed below) to see if it provides
a hint.
Thanks!
Andrew Prior
