3. IDE connectors (40-1 pin PRIMARY_IDE, SECONDARY_IDE)
This connector supports the provided UltraDMA100/66 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
UltraDMA100/66 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 devices, purchase another UltraDMA100/66 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.
