Note: A jumper consists of two or more pins mounted on the motherboard. When a jumper
cap is placed over two pins, it is designated as IN. When there are more than two
pins on the jumper, the pins to be shorted are indicated as 1-2 (to short pin 1 to pin
2), or 2-3 (to short pin 2 to pin 3). When no jumper cap is to be placed on the
jumper, it is designated as OUT. When a switch is designated as 1-2 the switch slide
is positioned such that pins 1 and 2 are shorted together.
4.4 Power On and Reset Buttons
The development board has two push buttons that implement POWER and RESET
functionality. The POWER button releases power to the entire development board,
causing the board to boot. The RESET button will force all systems to warm reset. The
two buttons are located near the CPU close to the edge of the development board. The
POWER button is located at SW1C1 and the RESET button is located at SW1C2.
Note: If the development board is powered from an external ATX power supply (not a power
brick), the Power button may need to be pressed twice to turn on the system.
