3. IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1) This connector supports the provided UltraDMA100/66 IDE ribbon cable. Connect the cable's blue connector to the primary (recommended) or secondary IDE connector, then connect the gray connector to the UltraDMA100/66 slave device (hard disk drive) and the black connector to the UltraDMA100/66 master device. It is recommended that you connect non-UltraDMA100/66 devices to the secondary IDE connector. If you install two hard disks, 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. BIOS supports specific device bootup. If you have more than two UltraDMA100/66/33 devices, purchase another UltraDMA100/66/33 cable. You may configure two hard disks to be both master devices with two ribbon cables - one for the primary IDE connector and another for the secondary IDE connector. 1. Pin 20 on each IDE connector is removed to match the covered hole on the UltraDMA cable connector. This prevents incorrect orientation when you connect the cables. 2. The hole near the blue connector on the UltraDMA100/66 cable is intentional. 3. For UltraDMA100/66 IDE devices, use the 80-conductor IDE cable. ® P4P8X SE P4P8X SE IDE Connectors PRI_IDE1 SEC_IDE1 NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1.
