DIP Switch 1:
Core/Bus Ratio
The red "DIP" Switch labeled SW1
is located on the P3TDE6. SW1

which are used to set the core/
bus ration. The table on the right
will show you which CPU Core/
Bus Ratio to use. The general rule
is to divide the CPU speed by the
bus speed (133 or 100 MHz for the
P3TDE6). For example, if you
have a 550 MHz CPU, dividing it by
100 will give you a CPU Core/BUS
Ratio of 5.5. After determining the
CPU Core/Bus Ratio, refer to the
table on the right for the correct
settings of DIP SW 1.
