USB Wake-Up
Use JPUSB to enable or disable USB
Wake-Up, which allows you to wake
the system up by pressing a key on
the keyboard or by clicking the mouse
when it is connected to the USB0
or USB1 port. This jumper is used
together with the USB Wake-Up func-
tion in the BIOS. Enable both jumper
setting and the BIOS setting to allow
the system to be awakened. See the
table on the right for jumper settings.

gram freezes. Close pins 2-3 to gen-
erate a non-maskable interrupt for the
