CONNECTORS

The connectors on the mainboard are either the pin header type or D-type
connectors, they are used to connect the accessories or peripheral devices (such as
power, mouse, printer,...etc.). Followings are the connectors with its description
and the pin assignment which is designed on the mainboard.
