2.7 Switches and jumpers
The motherboard frequency is adjusted through the DIP switches. The
white block represents the switch position. The illustration below shows all
the switches in the OFF position.
The JEN jumper is set in conjunction with the DIP switches. In
JumperFree mode, set all the DIP switches to OFF.
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.
The JEN jumper must be set to pins 1-2 (jumper mode) if you wish to
use the DIP switches. Otherwise, setting the switches does not
produce any effect.
