Chapter 1: Product introduction

3. IDE connectors (40-1 pin PRI_IDE)

The onboard IDE connector is for an Ultra DMA 133/100/66 signal cable.

There are three connectors on each Ultra DMA 133/100/66 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 device(s).

• 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.

• Use the 80-conductor IDE cable for Ultra DMA 133/100/66 IDE devices.

If any device jumper is set as “Cable-Select,” ensure that all other device

jumpers have the same setting.
