• 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,” ensure that all other device jumpers have the
same setting.
