DIP Switch 4:

Processor Speed

The red "DIP" switch labeled SW4
has four individual switches,
which are used to set the speed
of the processor.
The table on the right shows you
the switch settings for the various
speeds your processor may be
able to run at. (This table is also
silkscreened on the motherboard.)
Note: Most Intel processors have
a fixed Core/Bus ratio that over-
writes the setting of DIP Switch 4.

5-11 Jumper Settings

Explanation of

Jumpers

To modify the operation of the
motherboard, jumpers can be
used to choose between
optional settings. Jumpers
create shorts between two pins
to change the function of the
connector. Pin 1 is identified
with a square solder pad on
the printed circuit board. See
the motherboard layout pages
for jumper locations.
Note: On two pin jumpers,
"Closed" means the jumper is
on and "Open" means the
jumper is off the pins.
