The CompactFlash disk card is defaulted as the E: disk drive in your PC system.

1.2MB) and/or 3½” (720 KB, 1.44 MB, and 2.88 MB) drives is possible.

A34-pin daisy-chain drive connector cable is required for a dual- drive system. A 34-pin flat-cable connector is fitted on one end of the cable while the other end sports two sets of floppy disk drive connectors. Each set consists of a 34-pin flat-cable connector (for the 3½” drives) and a printed-circuit board connector (for the 5¼” drives).

2.Attach the appropriate conector at the other end of the cable to the floppy drive(s). You can use only one connector in the set. The set at the other 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 5¼” floppy drive, line up the slot in the printed circuit board with the blocked-off part of the cable connector.
