Step 2: CPU Single/Dual Voltage Setting
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
P54CX, AMD-K5-PRxxxBx, AMD-K5-PRxxxCx, AMD-K5-PRxxxFx,
and Cyrix 6x86. Refer to the following figure to set these CPUsÕ

Dual Voltage CPU Setting (Optional)
Dual voltage CPUs are designed to use different voltage for VIO and
VCore and they include Intel P55CX, AMD-K5-PRxxxHx, AMD-K5-
PRxxxJx, AMD-K5-PRxxxKx, AMD K6, Cyrix 6x86L, and Cyrix M2.
