2.14 Floppy Drive Connector (CN3)

With two options on flooy drive you could simply adopt any of the

combinations of 5.25" (360 KB and 1.2 MB) and/or 3.5" (720 KB,

1.44 MB, and 2.88 MB) drives onto the mainboard.

A 34-pin daisy-chain drive connector cable is required for a dual-

drive system. On one end of the cable is a 34-pin flat-cable connec-

tor. On the other end are two sets of floppy disk drive connectors.

Each set consists of a 34-pin flat-cable connector (usually used for

3.5" drives) and a printed-circuit board connector (usually used for

5.25" drives).

Wire number 1 on the cable is normally red or blue, and the other

wires are usually gray.

Connecting the floppy drive

1. Plug the 34-pin flat-cable connector into CN3. Make sure that

the red or blue wire corresponds to pin 1 on the connector.

2. Attach the appropriate connector on the other end of the cable

to the floppy drive(s). You can use only one connector in the

set. The set on the end (after the twist in the cable) connects to

the A: drive. The set in the middle connects to the B: drive.

3. If you are connecting a 5.25" floppy drive, line up the slot in the

printed circuit board with the blocked-off part of the cable

connector.

If you are connecting a 3.5" floppy drive, you may have trouble

determining which pin is pin number 1. Look for a number

printed on the circuit board indicating pin number 1. Also,

the connector on the floppy drive connector may have a slot.

When the slot is up, pin number 1 should be on the right.

Check the documentation that came with the drive for more

information.
