uninitialized, timed out

I'am new to LINUX but have been dealing with SCSI since day one. A
lot of this is still greek but I noticed in the debug dump the line listing
the three possiable cables. All three cables have zero devices attached to
them I guess since it says the cables are not present. You may have a SCSI
bus termination problem or other SCSI bus problems. It is very important to
have the SCSI bus terminated at both ends of the SCSI cable. Active
termination should be used. If using passive you need to run the SCSI bus
no faster than 5MB or disable sync mode. If you disable sync mode your bus
speed will be between 1 to 5 MB/sec. I belive the zip drives come as narrow
SCSI devices only and if attached to the 50 pin connector you do not need to
disable wide negotiation. You need to get the SCSI cable seen before you
can go any further, bad termination can work if the system is not pushed or
the moon is in the correct phase. Also beware of more than two terminators
on a SCSI bus or the mixing of active and pasive termination. Cable quality
and good connections are important as well as equal spacing between devices
and terminators.
