The C/D jumper is used to determine whether the drive is a master
(drive C) or a slave (drive D). The drive is configured as a master,
when jumpered, and a slave when not jumpered.

When using CS option, the C/D jumper MUST be open

Master/Slave Configuration
--------------------------
When two drives are daisy-chained on the host interface, one must be
designated at the master drive (C: drive) and one as the slave drive
(D: drive). Commands from the host are written in parallel to both
drives.

When the C/D jumper on the drive is closed, the drive will assume the
role of a master. When C/D is open, the drive will act as a slave. In
single-drive configurations, C/D must remain in the closed (master)
position.

For each command sent from the host, the DRV bit in the drive/head
register selects the master or the slave drive. When the DRV bit is
reset (0), the master drive is selected, and when the DRV bit is set
(1), the slave drive is selected.

Once the drives receive the command, only the drive with jumper C/D
set to the appropriate position will execute the command. For
example, if the DRV bit is set, only the slave drive (jumper C/D
open) will execute the command.

NOTE
If the command is a diagnostic command, both drives will execute the
command and the slave will report its status to the master via the
Host PDIAG signal.

Drive selection always refers to the state of the DRV bit in the
Device/Head register and the position of the position of the C/D
jumper throughout this manual.

Cable Select
------------
This optional method of drive master/slave designation can be enabled
by jumper selection as described below. If used, special cabling can
be used to selectively ground the CSEL interface signal of the
drive intended to be drive C (0). This drive will then function as
the master. If CSEL is allowed to float the drive will recognize it-
self as drive D (1) and function as the slave.
