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.
Bus Clock (JFS0-2): MHz Ratio (JBF0-2)
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 (JP1 & JP2)
Locate Jumper JP1 and JP2 on the mainboard (Refer to the diagram on
page 13). 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)
