 * Note: If you have #77701215k silk-screened near the 50-pin SCSI
         cable connector, the pin-1 for the 3 terminating resistors is
         away from the DC power connector.

 J4 11-12 Motor Start Option
 ---------------------------
 11-12 CLOSED  Enables the Motor Start Option. In this mode of
               operation the drive will wait for a Start Unit Command
               from the Host before starting the Motor.

J4 13-14 Parity Check
----------------------
13-14 CLOSED Parity checking is enabled.

Note: Pins on the drive select and configuration select header are
provided to facilitate manual drive configuration. No devices other
than jumpers should be connected to these pins. Improper connection
to external devices (switches, connectors, etc.) could adversely
affect drive performance. Exact location of these pins and headers
may change without notice.
