3. IDEconnector(40-1pinPRI_IDE)
The onboard IDE connector is for the 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 congure 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 100/66 IDE devices.
If any device jumper is set as “Cable-Select,” ensure that all other device
jumpers have the same setting.
