4. Voltage Regulator Output Selection (VID0, 1, 2)
These jumpers set the voltage supplied to the CPU. Current Intel CPU's marked
"Pentium" has only a Single Power Plane and uses the standard 3.38 volts (STD)
or 3.5 volts (VRE). Currently Intel's new Pentium P55C MMX 200MHz with
Dual Power Planes is supported at 2.8Volts. The voltage regulators will automati-
cally detect and switch between Single Power Plane and Dual Power Planes.
