III. HARDWARE SETUP

5.  External Connectors

IMPORTANT:  Ribbon cables should always be connected with the red stripe on Pin
1 side of the connector. The four corners of the connectors are labeled on the
motherboard.  Pin 1 is the side closest to the power connector on hard drives and some
floppy drives. IDE ribbon cables must be less than 18 in. (46 cm), with the second
drive connector no more than 6 in. (15 cm) from the first connector.

This connector supports either a standard IBM-compatible, 101/102-key, or 104-
key keyboard (Windows 95-compatible). Use a PS/2 keyboard adapter in order
to connect a PS/2 keyboard to this AT connector.

This motherboard accepts an AT Keyboard
Connector Plug as shown here.

This connector supports the provided floppy drive ribbon cable.  After connect-
ing the single end to the board, connect the two plugs on the other end to the
floppy drives.  (Pin 5 is removed to prevent inserting in the wrong orienta-
tion when using ribbon cables with pin 5 plugged).

Pin 1

 Some pins are used for connectors or power sources. These are

clearly separated from jumpers in “Layout Contents.” Placing jumper caps over
these will cause damage to your motherboard.
