4. IDE connector (40-1 pin PRI_IDE)
This connector is for an IDE 100/66 signal cable, a blue connector for the
primary IDE connector on the motherboard
• 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.
