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.
