IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
This connectors are for Ultra DMA 133/100/66 signal cables. The
Ultra DMA 133/100/66 signal cable has three connectors: a blue
connector for the primary IDE connector on the motherboard, a black
connector for an Ultra DMA 133/100/66 IDE slave device (optical
drive/hard disk drive), and a gray connector for an Ultra DMA
133/100/66 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 133/100/66 IDE
devices.
