Audio Line out and Speaker out Jumpers(JP2/JP3)
This jumper allows you to select between audio line-
out or speaker out function. Set both JP2 and JP3
pins to 1-2 for line-out function or set both JP2 and
JP3 pins to 2-3 for speaker out function..
Clear CMOS Data Jumper (JP4)
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.
CPU Bus Frequency (JP7/JP8)
This jumper allows the system bus frequency to be
determined either by CPU or the user. If set both JP7/
JP8 pins to 1-2, the CPU determines the system bus
frequency speed. Set both JP7/JP8 pins to 2-3 for
66MHz FSB, set only JP8 pins to 2-3 for 100MHz
FSB and leave both JP7/JP8 pins open for 133MHz
FSB.
