Abstract
A provided computer system has a variety of additional application functions such as television, audio, video, communication, game, home automation functions, etc., as well as general mathematical computation and logic functions. Also, the system has a switch circuit and a booting control circuit. The switch circuit is used in selecting the additional functions which has a plurality of switches corresponding to the functions respectively. The booting control circuit is operated with a first supply voltage VCC.sub.-- A which allows power supply to apply a second supply voltage VCC.sub.-- B to central processing unit, several kinds of memory units and input/output peripherals when at least one of the switches is on. The central processing unit loads basic input/output system routines into random access memory so as to initialize and check circuits of the computer system, and loads application routines for the additional functions into the random access memory without loading operating system routines when the at least one of the switches is on.
