2. Keyboard power (3-pin KBPWR)
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.
