6. IDE connector (40-1 pin PRI_IDE)
This connector is for an Ultra DMA 100/66 signal cable. The Ultra
DMA 100/66 signal cable has three connectors: a blue connector for
the primary IDE connector on the motherboard, a black connector for
an Ultra DMA 100/66 IDE slave device (optical drive/hard disk drive),
and a gray connector for an Ultra DMA 100/66 IDE 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 Ultra DMA cable connector. This prevents incorrect insertion
when you connect the IDE cable.
Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices.
NOTE: Orient the red markings
(usually zigzag) on the IDE
ribbon cable to PIN 1.
