5) CPU Bus Frequency Selector (FS0, FS1, FS2)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
AGPset. This allows the selection of the CPU's External frequency (or BUS Clock).
The Bus Clock multiplied by the Bus Multiple equals the CPU's Internal frequency
(the advertised CPU speed).

6) CPU Core:Bus Frequency Multiple (BF0, BF1, BF2, BF3)
This option sets the frequency multiple between the Internal frequency of the
CPU and the CPU's External frequency. These must be set in conjunction with the
CPU Bus Frequency.
