2. ICH7R primary IDE connectors (40-1 pin PRI_IDE1 and PRI_IDE3)
These connectors are for Ultra DMA 100 / 66 signal cables. 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.
