4.3 Connectors
1. Floppy disk drive connector (34-1 pin FLOPPY1)
This connector is for the provided floppy disk drive (FDD) signal cable. Insert
one end of the cable to this connector, then connect the other end to the
signal connector at the back of the floppy disk drive.
2. IDE connector (40-1 pin PRI_IDE1)
This connector is for an Ultra ATA 100/66/33 signal cable. By default, this
connector supports the optical disk drive. You must configure the optical drive
as master/slave device by setting its jumper accordingly. Refer to the optical
disk drive documentation for the jumper settings.
Pin 5 on the connector is removed to prevent incorrect cable connection when
using a FDD cable with a covered Pin 5.
Pin 20 on the IDE connectors is removed to match the covered hole on the Ultra
ATA cable connector. This prevents incorrect insertion when you connect the
IDE cable.
