modes (no power to CPU, DRAM in slow refresh, power supply in reduced
power mode). USBPW1-6 is for the rear USB ports. USBPW7-12 is for the
internal USB connectors that you can connect to additional USB ports.

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)s.
This feature requires an ATX power supply that can supply at least 1A on the
+5VSB lead, and a corresponding setting in the BIOS.
