Yes. It's the only external device, the others are internal. > 2 - Does the scanner have an external terminator? No. > 3 - Does the scanner have an internal terminator enabled? I don't know. The manual doesn't say anything about termination (!). I *supposed* it had an internal terminator, but I'm not sure anymore. > 4 - Is terminator power enabled on the SCSI controller card? Yes. This was correct for the old situation without scanner, but with the scanner attached it should be disabled. However, with the card terminator disabled the machine doesn't boot anymore beyond the point where it recognizes the scanner, so I suppose the scanner lacks termination. Because the manual doesn't contain useful information concerning this, I wrote an email to Trust, manufacturer of the scanner. I think I'll need an external terminator on the scanner.
