Step 2: CPU Single/Dual Voltage Setting
There are two kinds of CPU input voltages due to various designs of
CPUsÑsingle voltage and dual voltage. Set your CPU according to the
type that you have.
For Intel P54C/P55C series CPUs, there is no need to adjust any jumper
for CPU voltag due to the Smart Detect CPU Voltage function.
Single Voltage CPU Setting
Signal voltage CPUs use the same voltage for VIO and VCore and has
been used traditionally. The CPUs which fall into this category are Intel
P54C series, AMD-K5-PRxxxBx, AMD-K5-PRxxxCx, AMD-K5-
PRxxxFx, and Cyrix 6x86. Refer to the following figures to set these
CPUsÕ voltage:
