Switches and jumpers

The motherboard frequency is adjusted through the DIP switches. The
white block represents the switch position. The illustration below shows
the ON and OFF positions of the switches.
P4B533 DIP Switches
The JEN jumper must be set to pins 2-3 (jumper mode) if you wish to
use the DIP switches. Otherwise, setting the switches does not
produce any effect.
1. JumperFree™ mode (JEN)
This jumper allows you to enable or disable the JumperFree™ mode.
The JumperFree mode allows you to change CPU settings through the
BIOS setup instead of using the DIP switches.
