The two shrouded PCI IDE headers will interface four Enhanced IDE
(Integrated Drive Electronics) disk drives. To prevent improper 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 supports 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 (J1) 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 (J2) on
the system board and the other connectors to the IDE devices.
