5. CPU External (BUS) Frequency Selection (JP2, JP3)
These jumpers tells 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).
6. CPU to BUS Frequency Ratio (JP4, 5, 6, 7)
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.
Set the jumpers by the Internal speed of the
External Freq.:
