3. IDE connectors (40-1 pin PRIMARY_IDE, SECONDARY_IDE)

This connector supports the provided UltraDMA IDE hard disk ribbon cable.

Connect the cable’s blue connector to the primary (recommended) or secondary

IDE connector, then connect the gray connector to the UltraDMA100 device

(hard disk drive) and the black connector to the UltraDMA100 master device. It is recommended that you connect non-UltraDMA100 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 devices, purchase another UltraDMA 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.

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.

The hole near the blue connector on the UltraDMA cable is intentional.
