Abstract

A computer system and its booting and setting method are disclosed. Power supplying and a booting process of the computer system are controlled by a basic input/output system (BIOS). The computer system includes a super input/output chip, a south bridge chipset, and a power supply module. The super input/output chip includes a timer. A counting time is set by the BIOS and the timer counts down when booting the computer system, wherein the counting time is longer than a normal booting time. The south bridge chipset is electrically connected with the super input/output chip and exchanges data between a south bridge chipset and a peripheral device. The power supply module is used for providing power to the computer system. The BIOS controls the timer to stop counting down when the computer system is capable of booting normally.

Dependent claims

A computer system, wherein power supplying and a booting process of the computer system are controlled by a basic input/output system (BIOS), comprising:

a super input/output chip including a timer, wherein a counting time is set by the BIOS and the timer counts down when booting the computer system, and the counting time is longer than a normal booting time;
a south bridge chipset electrically connected with the super input/output chip and exchanging data between a host and a peripheral device;
and
a power supply module used for providing power to the computer system,
wherein the BIOS controls the timer to stop counting down when the computer system is capable of booting normally, a power-off process is executed to control the power supply module to stop providing power when the counting time is up, the super input/output chip sends a reboot signal to reboot the computer system after the power-off process is completed.

A computer system booting and setting method, wherein power supplying and booting of the computer system are controlled by a basic input/output system, the method comprising:

setting a counting time of a tinier of a super input/output chip when the computer system boots, wherein the counting time is longer than a normal booting time;
counting down by the timer;
stopping the timer counting down when the computer system boots normally;
making the computer system enter a power-off process when the counting time is up;
and
sending a reboot signal after the power-off process is completed to reboot the computer system;
wherein the step of entering a power-off process includes:
changing a power OK signal from high voltage to low voltage;
changing a second power-off control signal from low voltage to high voltage;
and
waiting until a switch control signal and a reset signal are changed from high voltage to low voltage,
wherein the computer system executes the power-off process when the switch control signal and the reset signal are changed from high voltage to low voltage.
