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.
