5-10 DIP Switch Settings
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.
N o t e : On two pin jumpers, "Closed" means the jumper is on and "Open" means the jumper is off the pins.
