Hello all I've been trying for months now to install RedHat Linux on a computer of mine that's using an Adaptec 3940UW controller. I have a Plextor Ultra SCSI 40X CDDrive and an internal SCSI Zip 100 Drive. Channel A is terminated on the adapter, and the end of the SCSI cable has an UW terminator built into it. On channel A the adaptor is ID#7, CDRom is #3 and Zip is #5 Channel B has only an UltraWide Seagate Cheetah 4.3GB drive on it. Both the controller and drive are set to terminate. Board's SCSI ID is also 7 here, the drive is 0. I'm sure of the hardware side of things, OS/2 v4 works perfectly on this setup. Now for the problem: When RedHat's installer tries to load the aic7xxx.o module, it detects channel A and everything on it perfectly. The trouble starts when it looks at channel B. The driver decides that the board's SCSI ID is set to 0, and then it finds my Seagate drive on every ID from 1 through 15. This causes 15 HDs with 6 partitions each to be detected, which is obviously wrong =) I don't know if it's important, but it also detects the drive's speed as 20MB/s when it should be 40. All other data on the drive, including geometry, is correct for each drive it finds =) This occurs with all versions of RedHat's boot disk images, up to and including the 5.9 release on ftp.redhat.com. I even tried making my own boot disk using a module built on another linux box of mine with the latest diff patches applied to a pristine 2.0.36 tree. Same problem. If anyone wants a list of the output from the module in order to help, just ask =) Thanks in advance for any help.
