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.
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.
