+
+ 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.
