4-10 Chapter 4: Motherboard information
2. IDE connector (40-1 pin PRI_IDE)
This connector is for an Ultra DMA 100/66 signal cable. The Ultra
DMA 100/66 signal cable has three connectors: a blue connector for
the primary IDE connector on the motherboard, a black connector for
an Ultra DMA 100/66 IDE slave device (optical drive/hard disk drive),
and a gray connector for an Ultra DMA 100/66 IDE master device (hard
disk drive). If you install two hard disk drives, you must congure the
second drive as a slave device by setting its jumper accordingly. Refer
to the hard disk documentation for the jumper settings.
4.3.2 Internal connectors
1. Floppy disk drive connector (34-1 pin FLOPPY1)
This connector is for the provided oppy 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 oppy 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 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.
