2. ICH7R Primary IDE connector (40-1 pin PRI_IDE1)
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
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.

1. 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.
NOTE: Orient the red markings on
the floppy ribbon cable to PIN 1.
