   +------+------+------+--------------------------------------------+

X indicates the jumper setting does not matter.

 Caution: The CS and DS jumpers should never be installed at the same
          time.

DS Drive Select Jumper
-----------------------
You can configure two drives on the ATA Interface as Master (Drive 0)
and Slave (Drive 1) using the DS jumpers. Set the CS jumpers to OPEN
for each drive. Then, set the DS Jumper to CLOSED on one drive to
configure that drive as Master. Set the DS jumper to OPEN on the
other drive to configure as Slave.

 Note: For drives configured using the DS jumper, the order in which
       drives are connected in a daisy chain has no significance.

CS Cable Select Jumper
-----------------------
When two ProDrive LPS 127/170/340AT hard disk drives are daisy-
chained together, they can be configured as Master and Slave by using
the CS jumper or by using the DS jumper - BUT NOT BOTH. To configure
the two drives using the CS jumper, set the CS jumper to CLOSED and
the DS jumper to OPEN on each drive.

Once you install the CS jumper, the drive is configured as a Master
or Slave by state of the Cable Select signal, which is pin 28 at the
IDE-bus interface connector. Quantum uses pin 28 as a vendor-specific
pin; it does NOT conform to the function normally allocated for this
pin according to the ATA (AT Attachment).

Pin 28 is grounded - that is, set to OPEN - on the cable coming from
the host. This configures the first drive as Master. Then, pin 28 on
the connector at the second drive should be made an open circuit by a
cut in signal line 28 in the cable from the first drive, so it
becomes high - that is, set to CLOSED - due to a pull-up in the
second drive. This configures the second drive as a Slave.

SP Slave Present Jumper
------------------------
The SP jumper normally is not needed. However, when the ProDrive LPS
127/170/340AT is configured as Master and is connected to a Slave
drive that does not implement the Drive Active/Slave Present (DASP-)
signal, it is necessary to set the SP jumper to CLOSED on the
ProDrive LPS 127/170/340AT.
