Summary: | According to the claimed invention, the computer system has a central processing unit, a north bridge electrically connected to the central processing unit, memory electrically connected to the north bridge, and a south bridge electrically connected to the north bridge, the south bridge having a general purpose serial input/output port. The computer also includes at least one peripheral device electrically connected to the south bridge and an interfacing circuit for providing a plurality of extended general purpose input/output ports, the interfacing circuit having a connection end electrically connected to the general purpose serial input/output port. When inputting a data signal from a general purpose input/output (GPIO) port, the data signal is transmitted to the general purpose serial input/output port through the connection end of the interfacing circuit. |
