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.
