6 . IDE connectors (40-1 pin PRI_IDE, SEC_IDE) These connectors are for Ultra DMA 100/66 signal cables. 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 cables. • Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices. NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1. SEC_IDE PRI_IDE P4P8T ® P4P8T IDE connectors PIN 1 7 .
