 Install master/slave jumpers
 ----------------------------
 In a two-drive system, you need to designate one drive as the master,
 or drive 0, and the other drive as the slave, or drive 1. In a one-
 drive system, configure the drive as a master (no jumpers installed).

 Alternatively, you can configure the drive as a master or slave
 using the cable select option. To use this option, the host system
 and both drives must support cable select. Cable selection requires
 a special daisy-chain cable that grounds pin 28 (CSEL) on one of its
 two drive connectors. If you attach the drive to the grounded CSEL
 connector, it becomes a master. If you attach the drive to the
 ungrounded CSEL connector, it becomes a slave.

 To configure the drive for cable select, install both master/slave
 jumpers.


 Drives uses +5vdc power supplied to the drive via the interface
 connector. The drive does NOT make use of a +12vdc power line.
