This jumper allows you to enable or disable the keyboard wake-up feature. When you
set this jumper to pins 2-3 (+5VSB), you can wake up the computer by pressing 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.
