 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.
