IMPORTANT: For UltraDMA/100/66 IDE devices,use a 40-pin 80-conductor IDE
cable. The UltraDMA/66 cable included in the motherboard package also
supports UltraDMA/100.
12) Primary (Blue) / Secondary IDE Connectors (40-1 pin IDE1/IDE2)
These connectors support the UltraDMA/100/66 IDE hard disk ribbon cable
supplied with the motherboard. Connect the cables blue connector to the primary
(recommended) or secondary IDE connector, then connect the gray connector to
the UltraDMA/100/66 slave device (hard disk drive) and the black connector to
the UltraDMA/100/66 master device. It is recommended that non-UltraDMA/
100/66 devices be connected 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 (see 4.6 Boot Menu). If you have more
than two UltraDMA/100/66 devices, purchase another UltraDMA/100/66 cable.
NOTES:
1. 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.
2. The hole near the blue connector on the UltraDMA/100/66 cable is
intentional.
TIP: You may configure two hard disks to be both Masters with two ribbon
cables: one for the primary IDE connector and another for the secondary
IDE connector.
