This section describes and illustrates the connectors on the motherboard.

1. IDE connectors (40-1 pin IDE1, IDE2)

This connector supports the provided UltraDMA 66/100/133 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 66/100/133 slave device (hard disk drive) and the

black connector to the UltraDMA 66/100/133 master device. It is

recommended that you connect non-UltraDMA 66/100/133 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 66/100/133 devices,

purchase another UltraDMA 66/100/133 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.

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.

For UltraDMA 66/100/133 IDE devices, use an 80-conductor IDE cable.
