3) CPU External Frequency Selection (DIP_SW Switches 5–8)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
the PCI bus. This allows the selection of the CPU’s External frequency (or BUS Clock).
The BUS Clock multiplied by the Frequency Multiple equals the CPU’s Internal
frequency (the advertised CPU speed).
