CPU Type (Vcpuio)
Single voltage CPU
Vcpuio = Vcore
(default)
Dual voltage CPU
Vcpuio = Vio
(PP/MT P55C)
Set the jumper JP9, JP10 and
JP11 according to the type of
CPU. They are actually the
selection of CPU I/O Voltage
(Vcpuio). Normally, for single
voltage CPU, Vcpuio is equal to
Vcore, but for CPU that needs
dual voltage such as PP/MT
(P55C), Cyrix 6x86L, Vcpuio must
be set to Vio, and it is different
from Vcore.
