2. Keyboard/Mouse power (3-pin USB_KBMS_PW)
This jumper allows you to enable or disable the keyboard / mouse wake-up
and Wake-On-LAN 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), or click the mouse buttons. You can also wake up the computer from
another computer in LAN. This feature requires an ATX power supply that
can supply at least 1A on the +5VSB lead, and a corresponding setting in the
BIOS.
3. Fan power (3-pin PWR_FAN)
Set this jumper to 1-2 (Default) if you are using a 4-pin CPU fan. Set this
jumper to 2-3 if you are using a 3-pin CPU fan.
