DIP Switch 1:
Core/Bus Ratio
A red DIP switch labeled SW1 is
included on the mother-
board. This DIP switch has four
individual switches and is used to
set the CPU core/bus ratio. The
example on the right will show you
which CPU core/bus ratio to use.
After determining the ratio, refer to
Table 5-17 for the correct settings
of DIP switch 1.

Core/bus ratio = CPU speed / front
side bus speed. Example: a 550 MHz
CPU running at a 100 MHz FSB
speed:
550 (MHz) / 100 (MHz) = 5.5 (ratio)
