1.12 Connectors

This section describes and illustrates the connectors on the motherboard.
1. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
This connector supports the provided UltraATA133/100/66/33 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 UltraATA133/100/66/33 slave device (hard disk drive) and the black
connector to the UltraATA133/100/66/33 master device. It is recommended that
you connect non-UltraATA133/100/66/33 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 UltraATA133/100/66/33 devices, purchase another
UltraATA133/100/66/33 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.
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 UltraATA133/100/66/33 IDE devices, use 40-pin 80-conductor cable.
