2-2 Chapter 2: Hardware information
2.8.2 Internal 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 connector (40-1 pin PRI_IDE)
The onboard IDE connector is for the Ultra DMA (133/)100/66 signal cable.
There are three connectors on each Ultra DMA 133/100/66 signal cable:
blue, black, and gray. Connect the blue connector to the motherboard’s IDE
connector, then select one of the following modes to configure your device.

the floppy ribbon cable to PIN1.

• 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 133/100/66 IDE devices.
If any device jumper is set as “Cable-Select,” make sure all other device
jumpers have the same setting.
