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 pin 1
of the drive edge connector(s). The end-most connector should be
attached to the drive you want to designate as Drive A.
IDE Hard Disk Interface
The 686IPK system board is equipped with two shrouded PCI IDE
headers that will interface four Enhanced IDE (Integrated Drive Elec-
tronics) 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.
Note:
An IDE cable with a standard 40-pin connector (without the keying
mechanism) can be installed in the shrouded PCI IDE header. Be ex-
tremely careful to match the colored edge of the ribbon with pin 1 of the
header.
