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.

This prevents incorrect insertion when you connect the IDE cable. • Use the 80-conductor IDE cable for Ultra ATA 100/66/33 IDE devices. ASUS TS300-E5 4-
