3. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
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.
4. MDC header (10-1 pin MDC)
This ASUS proprietary modem header accomodates an optional modem
module.
