• 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 100/66/33 IDE
devices.
If any device jumper is set as “Cable-Select,” make sure all other device
jumpers have the same setting.
