ABSTRACT:
Since an instruction of switching of the system operation environment or configuration such as the power save mode and power-up mode is input by the hot key operation using SMI, key data of the hot key can be instantly received by the CPU even while any type of application program is being executed, and the operation environment is changed. Further, when the system operation environment or configuration such as the power save mode and power-up mode is changed, a pop-up window indicating the present system operation environment is automatically opened on the display image plane according to the rewritten operation environment or system configuration data of the CMOS memory. Therefore, the operation mode switched by the hot key function can be instantly indicated to the user. When an event mode is set, in response to a change of a power supply status, a power supply controller set data indicating the changing of the power supply status, into a predetermined register of the computer system. At this time, the power supply controller informs the CPU of the changing of the power supply status by using an interrupt signal.
