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
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.
