3. RAID connector (40-1 pin PRI_RAID)
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 RAID 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 RAID 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.
