DIP Switch (SW1) selects CPU voltage
Note: Different voltage may have the same DIP switch setting. For
example the DIP switch for 2.2V and 2.9V are identical same. The
“SMART” switching regulator design can auto-detect the CPU
type and generate the proper operating voltage for the CPU. For
example, with the same DIP switch setting, when a AMD K6-266
or 300MHz CPU plug-in, switching regulator will set to 2.2V and
if an AMD K6-200MHz CPU plug-in, switching regulator will set
to 2.9V.
