4. CPU External (BUS) Frequency Selection (FS0, FS1, FS2)

These jumpers tell the clock generator what frequency to send to the CPU. These

allow the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock

times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed).

5. CPU to BUS Frequency Ratio (BF0, BF1)

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.
