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
the ON and OFF positions of the switches.

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.

Set the JEN jumper to pins 1-2 (jumper mode) and the PSBSEL1
jumper to pins 2-3 (DSW1) if you wish to use the DSW1 switches.
Otherwise, setting the switches does not produce any effect.
The JEN jumper is set in conjunction with the DSW1 switches. In
JumperFree mode, set DSW1 switches as shown above.
