JP1 (AT/ATX Mode Selector)

This jumper block controls the way you connect to a power supply

The CN13 connector is used to connect a chassis power On/Off button using an adapter cable.

The CN13 connector is configured through the JP1 jumper. The use of this connector is

briefed as follows:

1. Using ATX power: CN13 connects to an externally implemented power switch, and

the JP1 jumper should be left open.

2. Using AT power: The pins on JP1 are shorted by a jumper cap. The reason why

JP1 should be shorted is because the AMD Southbridge is

designed without the consideration for a power button signal and

the shorted JP1 provides a hardware feedback to initiate the

system. The power on/off function is then managed by the AT

power switch button.
