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 specifi-
cation 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.
Power On By Keyboard (JP5)
This board is able to be turned on by the PS/2 keyboard (hot
key). To use this function, select a hot key of your choice at
the PS2KB Wakeup option under Wake Up Events in the BIOS's
Power On Management screen. You must also set this jumper's
cap to pins 2-3 to use this function.
Power On By USB 0/1 and 2/3 (JP6/JP6A)
This board is able to be turned on by a USB keyboard hot key
or a USB mouse click.
To use this function, select a hot key
of your choice at the USB Resume option under Wake Up Events
