[parisc-linux] 712/80 - 7cdroms - scsi prbl

[Brian Mockford]

Perhaps ---

This is a classic symptom of a SCSI device set with the same address as the
SCSI controller - normally 7 in a narrow SCSI environment.
Change the address of the CDROM to 4
You need to identify the CDROM SCSI address jumpers. (usually 3 pairs of
adjacent pins with plastic shorting jumpers on. If all three have jumpers
then it is likely the device is set to address 7. remove the middle jumper -
this will change it to address 4. There may still be a conflict with another
device , but the seven drives should "go away"
