These connectors are 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). If you install two hard disk drives, you must configure the
second drive as a slave device by setting its jumper accordingly. 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.
