8. Voltage Regulator Output Selection (JP20-JP26)
These jumpers set the voltage supplied to the CPU. Determine whether your
CPU has a single power plane or dual power planes and then the voltage that it
uses. 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). When a single power
plane CPU is installed, the dual power plane selections will be automatically
disabled. When a dual power plane CPU is installed, the single power plane
selections will be automatically disabled. You may have one jumper on the
Single Power Plane and another on the Dual Power Planes at the same time.
