Ok, I thought you were trying to use it as a boot device.
>But why do I need to disable parity?
It's just something I've found necessary. As long as all the devices have
parity either enabled or disabled it should be ok, but I'm not actually sure
of the reasons for having it all one way or the other. It's probably
device-driver related.

Only the *last* device on the SCSI chain should have termination enabled.
Most current narrow and wide SCSI drives have on-board active terminators
which are enabled by a jumper. But I usually use external terminators with
devices that are hanging off cables, so I always leave the terminator
enabling jumper off.
Regards,
Craig.
