3 IDE connector (40-1 pin PRI_EIDE)
The onboard IDE connectors are for Ultra DMA 133/100/66 signal
cable(s). 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 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 IDE
devices.
If any device jumper is set as “Cable-Select”, make sure all other device
jumpers have the same setting.
