Drive Select Jumpers
--------------------
Only one Drive Select jumper is installed on a drive. For every
drive in a PC/AT installation, move the jumper from DS1 to DS2 (the
special twisted interface cable that is generally used, takes care of
assigning a unique address to each drive). Some other systems may
require that each drive be jumpered to a unique address.
The drives are shipped with the jumper installed at DS1.

W1 Write Fault Latch
--------------------
W1 is the Write Fault Latch. If W1 is present and the drive
encounters a write fault, all writing to the drive is inhibited
until after the drive has been deselected. If W1 is absent, fault
conditions are not latched. Drives are shipped with a jumper
installed at W1; remove it for PC/AT installations.
W2 and W8 are always installed.
W7 Never install.
RN1 Interface Terminator
------------------------
The Interface Terminator factory installed at RN1 provides proper
termination for the interface lines. When daisy-chaining multiple
1300 drives, leave the terminator in the last physical drive on
the daisy chain cable; remove the terminator from each of the
other drives. In most PC/AT installations, the C: drive is actually
at the end of the cable and should retain the terminator.

MICROPL. 1300 SERIES PRODUCT DESCRIPTION
PC Drive Types
--------------
Examine the entries in your drive table and find the type that most
resembles the head and cylinder parameters of the drive without
exceeding the drive parameters. If you are using third-party
installation/partitioning software, follow the instructions included
with the software as it may perform this step automatically.
