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.
