The JP4 jumper block controls the connection to a power supply.

The CN5 connector is used to connect a chassis power On/Off button using an adapter

cable and is configured through the JP4 jumper. The CN5 connector has two operational

modes:

 Using ATX power: CN5 connects to an externally implemented power switch,

and the JP4 jumper should be left open.

 Using AT power: The pins on JP4 are shorted by a jumper cap. JP4 should be

shorted by default as the AMD® Southbridge is designed without the

consideration for a power button signal. The shorted JP4 provides a hardware

feedback to initiate the system. The power on/off function is then managed by

the AT power switch button.
