2. IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1)
The onboard IDE connectors are for Ultra DMA 133/100/66 signal
cables. 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 configure 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.
