3. CPU Bus Frequency (FS0, FS1, FS2)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
440BX AGPset. This allows the selection of the CPU’s External frequency (or BUS
Clock). The Bus Clock multiplied by the Bus Mult. equals the CPU’s Internal fre-
quency (the advertised CPU speed).
