3. 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.
