[parisc-linux] SCSI Disks on a K580 Help Required

[Averell Eisner]

Possible issues:

"First try." The internal disk drives in the K580 are fast wide 
differential. The differential is high voltage differential, not low 
voltage differential. Could be that the Maxtor 4.5GB UW is the wrong type.

"Second try." The normal cable in the K580 that goes to the tape and CD 
only has two open scsi connections plus the terminator. One connection 
for tape, another for the CD. Did you substitute another cable with a 
third open scsi connection?

Just guessing.
