Explanation of
Jumpers
To modify the operation of the
motherboard, jumpers can be

create shorts between two pins
to change the function of the
connector. Pin 1 is identified

the motherboard layout pages
for jumper locations. Note: On

DIP Switch Settings
DIP Switch 1:
Core/Bus Ratio
A red "DIP" switch labeled SW1 is
located on the P3TDE6. SW1 has
four individual switches, which
are used to set the core/bus ratio.
The example 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.
If you have a 550 MHz CPU, divid-
ing it by a 100 Mhz front side bus
will give you a CPU Core/BUS Ra-
tio of 5.5. After determining the
CPU Core/Bus Ratio, refer to Table
5-20 for the correct settings of DIP
Switch 1.
Note:
Most Intel processors have
a fixed Core/Bus ratio that will
overwrite the setting of DIP Switch
1.
550 (MHz) / 100 (MHz) = 5.5
CPU Speed / Bus Freq. = Ratio
