Rocker switches

The two rocker switches on the system board are used for custom configuration. For

the location of the small and large rocker switches, see items

and

above.

The large rocker switch has eight switches for setting microprocessor speeds for compatibility with the system board. The following table shows the rocker switch settings for compatibility with the corresponding microprocessor speeds.
