The Internal (Core) frequency corresponds to the number marked on the CPU. The External
Frequency when multiplied with the Ratio gives the CPU's internal frequency.

This jumper automatically sets the ISA Clock as well.
* If you are uncertain about the speed or voltage requirements of your particular CPU, you
should obtain Technical Documentation from the manufacturer. Such information is
available via the Intel, Cyrix and AMD WWW sites.
Setting the CPU Voltage Selection Jumper (JP5)
Locate Jumper JP5 on the mainboard (Refer to the diagram on page 8).
Set this jumper in accordance with your specific CPU type. The Intel
MMX CPU is an example of a dual supply chip (2.8V & 3.3V). When
single supply CPUs are used, this setting is not relevant and should be
left on the default. (Refer to the CPU documentation)
