1-20 Chapter 1: Product introduction
2. USB device wake-up (3-pin PS2_USBPWR1-4, USBPWR56,
USBPWR7-10)
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
500 mA on the +5VSB lead, and a corresponding setting in the BIOS.
