9. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
The PRI_IDE connector is for the UltraATA100 IDE hard disk ribbon
cable. Connect the cable's blue connector to the IDE connector, then
connect the gray connector to a slave device (optical drive) and the
black connector to the UltraATA100 master device (hard disk drive).
Refer to the hard disk documentation for the jumper settings.
Pin 20 on the IDE connector is removed to match the covered hole on
the UltraATA cable connector. This prevents incorrect orientation when
you connect the cables.
For UltraATA133 IDE devices, use an 80-conductor IDE cable.

to 150 MB/s data transfer rate, faster than the standard parallel ATA
with 133MB/s (Ultra ATA133).
