Step 14. CPU Voltage Smart-Detect (JP4)
This Mainboard automatically detects and adjusts the CPU voltage
to the proper value for Intel P54C/P55C and Cyrix 6x86(L) CPUs.
For some older models of CPU, their voltages can not be detected
correctly, remove the jumper to disable the Smart-Detect function.
If you are not familiar with the dual or single voltage setting of your
CPU, set JP4 to short (enable) and follow the CPU voltage setting
procedure in Chapter 2 / Step 3, to set the CPU operating voltage to
a correct value in order to avoid CPU damage.
