3.IDE connectors (40-1 pin PRI_IDE, SEC_IDE)

The PRI_IDE connector is for the UltraATA133 IDE hard disk ribbon cable. Connect the cable’s blue connector to the IDE connector, then connect the gray connector to a slave device (optical drive) and the black connector to the UltraATA133 master device (hard disk drive). Refer to the hard disk documentation for the jumper settings.

• Pin 20 on the IDE connector is removed to match the covered hole on the UltraATA cable connector. This prevents incorrect orientation when you connect the cables.

•For UltraATA133 IDE devices, use an 80-conductor IDE cable.

NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1.
