Clear CMOS Data (JP1)
To clear the contents of the CMOS, please follow
the steps below.
1. Disconnect the system power supply from the
power source.
2. Set the jumper cap at location 2~3 for 5 seconds,
then set it back to the default position.
3. Connect the system's power and then start the
system.
4. Enter BIOS's CMOS Setup Utility and choose
Load Setup Defaults. Type Y and press enter.
5. Set the system configuration in the Standard
CMOS Setup menu.
External Clock Frequency (JP2A/JP2B)
This jumper allows the system bus frequency to be
determined either by CPU or the user. If set both
JP2A/JP2B pins to 1-2, the CPU determines the
system bus frequency speed. Set both JP2A/JP2B
pins to 2-3 for 66MHz FSB, set only JP2B pins to
2-3 for 100MHz FSB and leave both JP2A/JP2B pins
open for 133MHz FSB.
Optional Frequency Ratio Setting (JP4)
This feature allows you to set a CPU at a higher
frequency clock ratio than it's specification allows.
it may or may not run at that ratio, depending on
the quality of your CPU and the extent to which the
ratio has been overset.
This option will not work with frequency lock CPU.
