SET THE SYSTEM PRIMARY JUMPER
To operate correctly, you must configure the system drive jumper so that the drive is recognized as the primary drive.
Each hard drive must be configured as either a primary or secondary device to operate correctly. A jumper is used to
configure a pair of connected hard drives to operate in a primary/secondary relationship. A jumper is a small plastic part
that slides over a pair of drive configuration pins. Figure 14 illustrates the rear panel of a 250 GB hard disk drive and the
jumper location.

Set the jumper (refer to Figure 15):
1. Using your fingernails or a pair of tweezers, remove the plastic jumper block by pulling it gently away from the drive.
2. Set the drive to be the primary disk by replacing the jumper block.
