I recently purchased a Microtek Scanmaker E3 with an Adaptec AHA-2940 SCSI card, from a friend who used it successfully on his debian system. I haven't had such luck!
The SCSI card wasn't discovered automatically. I learned that the 'aic7xxx' module was needed, so `modprobe aic7xxx` got me as far as the SCSI card, but no further. I still can't 'see' the scanner, or for that matter, any other device attached to the SCSI card. I have tried three different SCSI cards: AHA 2930U2, AHA-2940AU, and AHA-2940UW. I have tried three different SCSI cables. I have tried three different devices: The scanner, a SOny external CD-ROM, and an Exabyte external tape drive. Same result in all configurations: /proc/scsi/scsi shows only my Plextor CD-RW supported by ide-scsi (scsi0), and nothing behind scsi1, the Adaptec card. I tried rebuilding the initrd, including the AIC7xxx module so that it would be auto-loaded at boot. It still doesn't find any devices. I then re-arranged the order of modules, rebuilt the initrd, and rebooted. Now the aic7xxx device is scsi0, and ide-scsi is scsi1, and still only the plextor is detected! In addition to looking in /proc/scsi/scsi, `cdrecord --scanbus`, `sane-find-scanner`, and the 'disk utility' built-in to the Adaptec bios also show no devices attached!
What am I missing here?
Probably nothing.... but I've never tried an IDE/SCSI mix so it might have something to do with that. My comments are that you should try using the aic7xxx_old module. I have never had any luck using the aic7xxx module (written by Adaptec by the way) and especially using it with a 2940xx card. I recently installed SuSE 8.0 on a computer with a 2940UW and after the install, it refused to boot because of timeouts on the SCSI card. I had to recompile the kernel to use the aic7xxx_old before it would work. If, after getting an aic7xxx whatever module into initrd, and boot up recognizes the 2940 but you don't see any devices, then I would seriously wonder about the devices you have attached to it. Are the ID numbers on the devices set properly? (ID 7 is usually reserved for the controller itself) Is the BIOS for the controller being used? (not sure it should in an IDE/SCSI situation but I would think so). If the BIOS is in use and POST installs the bios correctly, then use the on-board diagnostics of the 2940 (CTL-A to get there) to check out the settings and the devices. -- +----------------------------------------------------------------------------+ + Bruce S.
