2.7.2 Internal connectors
1. IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1)
This connector supports the provided UltraATA100 IDE hard disk ribbon
cable. Connect the cable’s blue connector to the primary
(recommended) or secondary IDE connector, then connect the gray
connector to the UltraATA100 slave device (hard disk drive) and the
black connector to the UltraATA100 master device.
1. Follow the hard disk drive documentation when setting the device
in master or slave mode.
2. Pin 20 on each IDE connector is removed to match the covered hole
on the UltraATA cable connector. This prevents incorrect orientation
when you connect the cables.
3. The hole near the blue connector on the UltraATA cable is intentional.
