4. Keyboard power (3-pin KBPWR1)
This jumper allows you to enable or disable the keyboard wake-up
feature. Set this jumper to pins 2-3 (+5VSB) to wake up the computer
when you press a key on the keyboard (the default is the Space Bar).
This feature requires an ATX power supply that can supply at least 1A
on the +5VSB lead, and a corresponding setting in the BIOS.
5. VGA controller setting (3-pin VGA_EN1)
These jumpers allow you to enable or disable the onboard VGA
controller. Set to pins 1-2 to activate the VGA feature.
