Primary IDE connector (40-1 pin PRI_IDE1)

This connector is for an Ultra ATA100/66/33 signal cable. The Ultra

ATA 100/66/33 signal cable has three connectors: a blue connector for

the primary IDE connector on the motherboard, a black connector for an

Ultra ATA 100/66/33 IDE slave device (optical drive/hard disk drive),

and a gray connector for an Ultra ATA 100/66/33 IDE master device

(hard disk drive). 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.

Floppy disk drive connector (34-1 pin FLOPPY1)

This connector is for the provided floppy disk drive (FDD) signal cable.

Insert one end of the cable to this connector, then connect the other

end to the signal connector at the back of the floppy disk drive.

Pin 5 on the connector is removed to prevent incorrect cable connection

when using a FDD cable with a covered Pin 5.

•

Pin 20 on the IDE connector is removed to match the covered hole on

the Ultra ATA cable connector. This prevents incorrect insertion when

you connect the IDE cable.

•

Use the 80-conductor IDE cable for Ultra ATA 100/66/33 IDE devices.
