1. IDE connector (40-1 pin PRI_IDE)
The onboard IDE connector is for the Ultra DMA 133/100 signal cable. There are three
connectors on each Ultra DMA 133/100 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.
• 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 IDE devices.
If any device jumper is set as “Cable-Select”, ensure that all other device jumpers have the
same setting.
