1. CPU to BUS Frequency Ratio (JP13, 14, 15, 16)
These jumpers set the frequency ratio between the Internal frequency of the
CPU and the External frequency (called the BUS Clock) within the CPU. These
must be set together with the above jumpers CPU External (BUS) Frequency
Selection.
2. CPU External (BUS) Frequency Selection (JP6, 7)
These jumpers tells the chipset what frequency the CPU is using.
