3. IDE connectors (40-1 pin IDE1, IDE2)
This connector supports the provided UltraDMA/100/66/33 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
UltraDMA/100/66/33 slave device (hard disk drive) and the black connector to
the UltraDMA/100/66/33 master device. It is recommended that you connect
non-UltraDMA/100/66/33 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
UltraDMA/100/66/33 devices, purchase another UltraDMA/100/66/33 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 UltraDMA/100/66 cable is intentional.
