4.3 Internal connectors 1 . Floppy disk drive connector (34-1 pin FLOPPY1) This connector is for the provided floppy disk drive (FDD) signal cable.

K8N-DRE ¤ 1 FLOPPY1 NOTE: Orient the red markings on the floppy ribbon cable to PIN 1. K8N-DRE Floppy disk drive connector 2 . IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1) These connectors are for Ultra DMA 133/100/66 signal cables. The Ultra DMA 133/100/66 signal cable has three connectors: a blue connector for the primary IDE connector on the motherboard, a black connector for an Ultra DMA 133/100/66 IDE slave device (optical drive/hard disk drive), and a gray connector for an Ultra DMA 133/ 100/66 IDE master device (hard disk drive). If you install two hard disk drives to the same cable, 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. • The 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 DMA133/100/66 IDE devices.
