4.3 Connectors

1 . Floppy disk drive connector (34-1 pin FLOPPY)

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.

2 . IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1)

These connectors are for Ultra DMA 100/66 signal cables. The Ultra DMA 100/66 signal cable has two connectors: a blue connector for the primary IDE connector on the motherboard and a black connector for an Ultra DMA 100/66 IDE slave device (optical drive/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.

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

on the Ultra DMA cable connector. This prevents incorrect insertion when you connect the IDE cable.

•Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices.
