2.5

CPU TO BUS FREQUENCY RATIO (S7,S8,S9)

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 below jumpers CPU External (Bus) Frequency Selection.
2.6 CPU EXTERNAL (BUS) FREQUENCY
SELECTION (S10,S11,S12)
These switches tell the clock generator what frequency to send to the CPU. The Bus
clock times the Bus Ratio equals the CPU's Internal frequency.
