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). 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 ATA cable connector. This prevents incorrect
orientation when you connect the cables.
• For Ultra ATA/133 IDE devices, use an 80-conductor IDE cable.
