IDE Hard Disk Interface
The system board is equipped with two shrouded PCI IDE
headers that will interface four Enhanced IDE (Integrated Drive
Electronics) hard disk drives.
Connecting the IDE Hard Disk Interface
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.

2. Install the other 34-pin header
connector(s) into the disk drive(s).
Align the colored edge of the
daisy chained ribbon cable with

connector(s). The end-most connector should be attached to
the drive you want to designate as Drive A.
