JP3: Clear CMOS Memory Jumper
Use this jumper to clear the contents of the CMOS memory. The setup utility is
stored in CMOS, so you might need to clear this memory if incorrect setup data is
stopping your system from starting, or your system can not boot-up because you
forgot password and the system BIOS has been updated. Please following instructions
can be performed to clear CMOS memory.
Disconnect the ATX power supply cable from the motherboard, then move the
jumper cap to short Pins 2-3 of JP3 for 3-5 seconds.
Return the jumper cap to Pins 1-2 (normal setting) of JP3.
Reconnect the power supply cable and turn on your system power. Then
access BIOS setup, please refer to the BIOS configuration application.
JP1: PS/2 Keyboard/Mouse Power On Jumper
System power can be turned on by a PS/2 keyboard or a PS/2 mouse. To enable the
Power On by PS/2 keyboard or mouse feature, you need to short JP1 pin1-2 and set
"Power On Function" in "Integrated Peripherals" setup accordingly. See chapter 3
BIOS setup for more information.
