2. IDE connector (40-1 pin PRI_IDE)
The onboard IDE connector is for Ultra DMA 133 / 100 / 66 / 33 signal cable.
There are three connectors on each Ultra DMA 133 / 100 / 66 / 33 signal
cable: blue, black, and gray. Connect the blue connector to the motherboard’s
IDE connector, then select one of the following modes to congure 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 / 33 IDE
devices.
If any device jumper is set as “Cable-Select”, ensure that all other device
jumpers have the same setting.
