2. IDE connector (40-1 pin PRI_IDE)
This connector is for an Ultra DMA 100/66 signal cable. If you install
two hard disk drives, you must configure the second drive as a slave
device by setting its jumper accordingly. 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.
2.7.2 Internal connectors

other end to the signal connector at the back of the floppy disk drive.
Pin 5 on the connector is removed to prevent incorrect cable connection
when using a FDD cable with a covered Pin 5.
