Here is the output from a boot that caueses the last device in the SCSI
chain to be disabeled.If I go into the SCSI Bios and disable wide
negotiation for the CD and DAT all works fine. It seems odd that I
would have to do this, and it could be a burden if I connected a wide
device to the bus and forgot to go re-enable wide negotiation.
Any suggestions???
