1.12 Connectors
This section describes and illustrates the connectors on the motherboard.
1. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
This connector supports the provided UltraDMA IDE hard disk ribbon cable.
Connect the cable’s blue connector to the primary (recommended) or
secondary IDE connector, then connect the gray connector to the
UltraDMA133 slave device (hard disk drive) and the black connector to the
UltraDMA133 master device.
Pin 20 on each IDE connector is removed to match the covered hole on the
UltraDMA cable connector. This prevents incorrect orientation when you
connect the cables.
For UltraDMA133 IDE devices, use 40-pin 80-conductor cable.
