Jumpers
1. 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) if you wish to wake up the
computer when you press a key on the keyboard (the default is the
Space Bar).
This feature requires a power supply that can provide 500mA on the
+5VSB lead. Otherwise the system does not power up.
