3. IDE connector (40-1 pin PRI_IDE)
The onboard IDE connector is for the 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.
Single device
Two 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.
• Use the 80-conductor IDE cable for Ultra DMA 133/100/66 IDE devices.
If any device jumper is set as "Cable-Select," make sure all other device jumpers have the
same setting.
