5 . ATX power connectors (24-pin EATXPWR,4-pin ATX12V1, 4-pin ATX12V2)

These connectors are for the 20-pin and 4-pin power plugs from the power supply unit. The plugs from the power supply unit are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit.

6 . IDE connector (40-1 pin PRI_IDE)

The PRI_IDE connector is for the Ultra ATA/100 IDE hard disk ribbon cable. Connect the cable’s blue connector to the IDE connector, then connect the gray connector to a slave device (optical drive) and the black connector to the Ultra ATA/100 master device (hard disk drive). Refer to the hard disk documentation for the jumper settings.

• Pin 20 on the IDE connector is removed to match the covered hole on the UltraATA cable connector. This prevents incorrect orientation when you connect the cables.

•For Ultra ATA/133 IDE devices, use an 80-conductor IDE cable.

NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1.
