Note:
Only IDE hard drives or ATAPI CD-ROMs can be connected to the IDE
interface.
Connecting the IDE Hard Disk Interface
To prevent improper IDE cable installation, each PCI IDE shrouded
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.
Note:
The IDE cable with a standard 40-pin connector (without the keying
mechanism) can be installed in the PCI IDE shrouded header. Be ex-
tremely careful to match the colored edge of the ribbon with pin 1 of the
header.
Connecting the Hard Disk Cable
1.
If you are connecting two hard drives, install the 40-pin connector of
the IDE cable into the primary IDE shrouded header (connector J8).
If you are adding a third or fourth IDE device, install the 40-pin
connector of the other IDE cable into the secondary IDE shrouded
header (connector J9).
