4. IDE connector (40-1 pin PRI_EIDE)
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 congure 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 133/100/66 IDE devices.
If any device jumper is set as “Cable-Select,” make sure all other device jumpers have the
same setting.
