III. HARDWARE SETUP
4. CPU External Frequency Selection (FS0, FS1, FS2, FS3)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
440ZX AGPset. This allows the selection of the CPU's External frequency. The CPU
External Frequency multiplied by the Frequency Multiple equals the CPU's Internal
frequency (the advertised CPU speed).
