Reference to Appendix A for CPU voltage setting detail.
2.3.4 CPU Voltage (JP4)
The manufacture default is “Auto”. This jumper set the voltage for the CPU.
For example, the Intel Pentium P54 CPU uses 3.38V(STD)or 3.52V (VRE).
The new Pentium with MMX 200MHz CPU uses the dual power source and
more “Green” concept at 2.83V. This motherboard provides a jumper for
different application purpose or the user choose the “Auto” for automatically
detect the processor.
Reference to the Appendix A for more detail description on the CPU.
most of them are not using the same voltage for the processor. For example,
the current Intel Pentium processor is using 3.52V single power source and
new Intel Pentium with MMX processor is using the 2.83V dual power source.
