2. IDE connector (40-1 pin PRI_IDE, SEC_IDE)
The onboard IDE connector is for the Ultra DMA 133/100/66/33
signal cable. There are four connectors on each Ultra DMA
133/100/66/33 signal cable: blue, black, and gray. Connect the blue
connector to the motherboard’s IDE connector, then select one of the
following modes to congure your device.
• 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 133/100/66/33 IDE
devices.
If any device jumper is set as “Cable-Select,” make sure all other device
jumpers have the same setting.
