Connecting Floppy Disk Drives
The motherboard floppy disk drive controller con-
nector uses the narrower (34-pin) of the two supplied
cables. There are three connectors on the cable, one
at each end and one in the middle, more towards one
end. The end with two connectors closer together
goes to the disk drives. The other end connects to the
motherboard.
Always connect the Pin 1 side of the ribbon cable
(the colored edge) to the Pin 1 side of the cable con-
nector on the motherboard or device. The Pin 1 cor-
ner is marked on the motherboard and drives usually
have it marked in some way. The rule of thumb for
drives is that the Pin 1 side of the connector is on the
drive power connector side.
The end drive connector on the ribbon cable is for
floppy disk drive Drive A: and the middle connector
is for Drive B:. The supplied cable only supports
1.44MB floppy disk drives.

Connecting IDE Devices

The motherboard EIDE device controller connector
uses the wider (40-pin) of the two supplied cables.
There are three connectors on the cable, one at each
end and one in the middle, more towards one end.
The end with two connectors closer together goes to
the IDE devices. The other end connects to the
motherboard.
Always connect the Pin 1 side of the ribbon cable
(the colored edge) to the Pin 1 side of the cable con-
nector on the motherboard or device. The Pin 1 cor-
ner is marked on the motherboard and IDE devices
usually have it marked in some way. The rule of
thumb for IDE devices is that the Pin 1 side of the
connector is on the drive power connector side.
