Step 9 Attach Floppy Drive
FLOPPY
FLOPPY is a 34-pin dual-inline berg. Connect the cable from the floppy drive
to FLOPPY, as shown below. The onboard floppy controller cannot be used if
a hard disk card with a floppy controller is installed. Choose Standard Setup
and Peripheral Setup to configure the floppy controller.
The motherboard supports up to two 720 KB, 1.44 MB, or 2.88 MB 3½"
drives and 360 KB and 1.2 MB 5¼" drives. The connecting cable is a 34-pin
ribbon connector with two 34-pin edge connectors for attaching the floppy
disk drives. There is a small twist in the cable between the floppy connectors.
The last (end) connector should be connected to floppy drive A:.
