NOTES:
Overclocking your processor is not recommended. It may result in a slower
speed. Voltage Regulator Output Selection (VID) is not required for Pentium III/II/
Celeron processors because they send VID signals directly to the onboard power
regulator.
Set the jumpers by the Internal speed of your processor as follows:

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.
