PREPARING THE SMARTDRIVE

Before you install a SmartDrive, you must configure it for use in the
computer.

NOTE: The drive type number and non-standard drive configuration data are
      printed on a label on the drive. Record this information before
      beginning installation. You will need this information when you
      configure your system using the setup utility.

The SmartDrive has three pairs of jumper pins (Jumper Block J8) near the
connectors at the rear of the drive.

A jumper is a clip that contains metal contacts. To install a jumper, place
it over two adjacent pins. This installation connects or bypasses a circuit,
enabling or disabling a function.

Decide which drive configuration is best for your system. Refer to the
following diagram and table to install the appropriate jumper.

The following table summarizes the jumper settings:
