The two shrouded PCI IDE headers are used to interface four En-
hanced IDE (Integrated Drive Electronics) disk drives. To prevent im-
proper IDE cable installation, each shrouded PCI IDE header has a
keying mechanism. The 40-pin connector on the IDE cable can be
placed into the header only if pin 1 of the connector is aligned with
pin 1 of the header.
Each IDE connector suppor ts 2 devices, a Master and a Slave. Use
an IDE ribbon cable to connect the drives to the system board. An
IDE ribbon cable have 3 connectors on them, one that plugs into an
IDE connector on the system board and the other 2 connects to
IDE devices. The connector at the end of the cable is for the Master
drive and the connector in the middle of the cable is for the Slave
drive.
Connecting the IDE Disk Drive Cable
Install one end of the IDE cable into the IDE 1 header (J23) on the
system board and the other connectors to the IDE devices.
If you are adding a third or fourth IDE device, use another IDE
cable and install one end of the cable into the IDE 2 header (J20)
on the system board and the other connectors to the IDE devices.
