Connecting IDE Hard Disk Drives

The IDE connector supports Ultra ATA 133/100/66 IDE hard disk drives.

1.Connect the blue connector (the cable end with a single connector) to the motherboard.

2.Connect the black connector (the cable with the two closely spaced black and gray connectors) to the Ultra ATA master device.

3.Connect the gray connector to a slave device.

If you install two hard disk drives, 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.
