1.11 Connectors

This section describes and illustrates the connectors on the motherboard.
1. IDE connectors (40-1 pin IDE1, IDE2)
This connector supports the provided UltraDMA/133/100/66 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 UltraDMA/133/100/66 slave device (hard disk drive)
and the black connector to the UltraDMA/133/100/66 master device.
It is recommended that you connect non-UltraDMA/133/100/66
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 UltraDMA/133/100/66 devices, purchase another
UltraDMA/133/100/66 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.
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/133/100/66 IDE devices, use an 80-conductor IDE
cable.
