Primary IDE connectors (40-1 pin PRI_IDE, SEC_IDE)

These connectors are for an Ultra DMA 100/66 signal cable. The Ultra

DMA 100/66 signal cable has three connectors: a blue connector for the

primary IDE connector on the motherboard, a black connector for an Ultra

DMA 100/66 IDE slave device (optical drive/hard disk drive), and a gray

connector for an Ultra DMA 100/66 IDE master device (hard disk drive). If

you install two hard disk drives, you must configure the second drive as a

slave device by setting its jumper accordingly. Refer to the hard disk

documentation for the jumper settings.

• 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.
