3. IDE connector (40-1 pin PRI_IDE)
The onboard IDE connector is for an Ultra DMA 100/66 signal cable. There are three
connectors on each Ultra DMA 100/66 signal cable: blue, black, and gray. Connect the
blue connector to the motherboard’s IDE connector, then select one of the following
modes to configure your devices.

Pin 20 on the IDE connector is removed to match the covered hole on the Ultra DMA cable
connector. This prevents incorrect insertion when you connect the IDE cable.
• If any device jumper is set as “Cable-Select”, ensure that all other device jumpers have
the same setting.
• Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices.
