USB Wake-Up
Use JPUSB1 to enable or disable
USB Wake-Up, which allows you
to wakeup the system by de-
pressing a key on the keyboard or
by clicking the mouse when either
is connected to the USB1 or USB2
port. This jumper is used together
with the USB Wake-Up function in
the BIOS. Enable both the jumper
and the BIOS setting to allow the
system to be woken up. See the
table on the right for jumper set-
tings.

CMOS Clear
JBT1 is not actually a jumper but
consists of two contact pads. To
clear the contents of CMOS, short
these pads together by touching
them both with a metal conductor
such as the head of a small
screwdriver. JBT1 is located near
the ICHR6 chip on the P8SAA.
Note: for ATX power supplies,
you must completely shut down
the system and remove the AC
power cord before clearing CMOS.
