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 UltraDMA133/100 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 slave device (hard disk drive) and the black connector to the
UltraDMA133/100 master device. It is recommended that you connect non-
UltraDMA133/100 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 devices, purchase another UltraDMA133/100 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 UltraDMA133/100 IDE devices, use 40-pin 80-conductor cable.
