:
If you have split power plane CPU ( There are different Voltage between
CPU Core and I/O ), Please check CPU vendor or us in order to decide
core voltage value of JP17.
Check your processor documentation for correct voltage setting to avoid
the damage of CPU.
Single Voltage CPU : Intel Pentium and OverDrive series, Cyrix 6x86,
AMD K5.
Dual Voltage CPU: Intel Pentium with MMX technology (P55C),
Cyrix 6x86 L, M2 dual voltage, AMD K5 dual voltage CPU.
