HARDWARE SETUP 2) CPU External Frequency Selection (DSW-Switches 7-10) 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).
