3. IDE connectors (two 40-1 pin PRIMARY IDE/SECONDARY IDE)
These connectors support the provided UltraDMA/133/100/66 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 UltraDMA/133/100/66 slave device (hard disk drive)
and the black connector to the UltraDMA/100/66 master device. It is
recommended that you connect non-UltraDMA/100/66 devices to the
secondary IDE connector.
If you install only one hard disk, configure the drive as a master device
by setting its jumper accordingly. If you install two hard disks, you must
configure the second drive as a slave device. Refer to the hard disk
documentation for the jumper settings. BIOS supports specific device
bootup. If you have more than two UltraDMA/133/100/66 devices,
purchase another UltraDMA/133/100/66 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 UltraDMA/133/100/66
cable is intentional.
For UltraDMA/133/100/66 IDE devices, use an 80-conductor IDE cable.
The UltraDMA/66 cable included in the motherboard package also
supports UltraDMA/100.
