2. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
This connector supports the provided UltraDMA133/100/66 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 UltraDMA133/100/66 slave device (hard disk drive)
and the black connector to the UltraDMA133/100/66 master device. It
is recommended that you connect non-UltraDMA133/100/66 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 UltraDMA133/100/66 devices, purchase another UltraDMA133/
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.

For UltraDMA133/100/66 IDE devices, use an 80-conductor IDE cable.
The UltraDMA/66 cable included in the motherboard package also
supports UltraDMA133 or UltraDMA100.
• 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 UltraDMA100/66 cable is
intentional.
