The motherboard frequency is adjusted through the DIP switches. The white

switches in the OFF position.

This jumper enables or disables the JumperFree™ mode. The JumperFree™
mode supports processor settings to be made through the BIOS setup.

Otherwise, setting the DSW switches does not produce any effect.
