Technical field
The present invention relates to a kind of computer system and self-cooling method in startup process of computer system, particularly relate to a kind of computer system and the cool-down method during starting shooting thereof.
Background technology
Basic Input or Output System (BIOS) (BASIC INPUT/OUTPUT SYSTEM; BIOS) in startup process of computer system, play the part of epochmaking role.BIOS is a firmware program (FirmwareProgram), and it is stored in the ROM (read-only memory) (ROM), the most basic hardware initialization (initialize), the necessary program code of peripheral unit control so that booting computer (Boot) to be provided.
In the moment of booting computer, processor can be obtained program code in the BIOS internal memory on the motherboard, is just controlled the initial actuating of computer by the program code of BIOS internal memory inside.The BIOS most important work comprises that the start oneself detects (Power On Self Test; POST) with functions such as initialization and tests.Wherein, during booting computer, BIOS gives with control in system, BIOS can check earlier whether buffer (Registers), the flag (Flages) of processor operate normally, then check timer (timer) but whether program interrupt controller (Programmable interrupt controller) and direct memory access controller devices such as (DMAcontroller) normal.In addition, BIOS can each chipset of initialization (chipset), the buffer of internal memory (RAM), video card (Video-Card) and related peripheral device, and tests its whether operate as normal.
In recent years, for improving computer work efficient, computer processor is the productive setization more and more along with higher frequency speed.Yet frequency speed increases highly more, will produce many more heats in the processor.Add the heat energy that internal system chipset and high speed hard-disk are produced, impel the processor internal temperature sharply to increase and can't descend, will cause the improper or collapse of processor operations.
So general computer system is when processor and enclosure system temperature are too high, regular meeting is sharply heated up by processor and causes computer system start shooting again (Restart).Again after the start,, work as machine (Hang) or start (Restart) again after the start again once again often because processor and enclosure system temperature are still very high.In addition, computer system is made of many hard disks, the heat energy that it produced, the wait that is not the short time just can be lowered the temperature at once, therefore, when computer system once again behind machine, if etc. the computer system under the situation to be shut down lower the temperature naturally, in the reasonable time of will expending.
Summary of the invention
The invention provides a kind of computer system and self-cooling method in startup process of computer system, it utilizes BIOS in start process, regularly obtain the system temperature value, when judging that the system temperature value is higher than critical temperature value, the output of heating radiator or increase heating radiator will be started, after temperature is descended, carry out boot program again.
Computer system with start process self-cooling of the present invention comprises that a BIOS, who stores a critical temperature value is coupled to South Bridge chip, an i/o controller and the heating radiator of this BIOS.I/o controller is coupled to South Bridge chip, regularly detects a system temperature value, and when this system temperature value is higher than this critical temperature value, exports a control signal.Heating radiator is coupled to this i/o controller, is controlled by this control signal and starts.
In computer system of the present invention, the present invention also provides a kind of self-cooling method in startup process of computer system, and its step comprises: at first, start BIOS with the execution boot program, and BIOS is preset with a critical temperature value.Then, BIOS regularly obtains a system temperature value.Next, BIOS judges whether the system temperature value is higher than critical temperature value, is judged as to be, then BIOS stops boot program, and carries out cooling process.
In computer system of the present invention, the present invention also provides another self-cooling method in startup process of computer system, and its step comprises: at first, start BIOS with the execution boot program, and BIOS is preset with a critical temperature value.Then, BIOS loads critical temperature value to an i/o controller.Then, i/o controller is detected a system temperature value.Next, i/o controller judges whether the system temperature value is higher than critical temperature value, is judged as to be, then BIOS stops boot program, and carries out cooling process.
To sum up, temperature protection is protection hardware and the topmost factor of operating system for computer system.The characteristic of computer system product mainly is not to emphasize the quick turn-on flow process, but emphasizes the stability of system.
Therefore; according to above-mentioned characteristic; the present invention utilizes the operating and setting of BIOS; allow computer system in start process; can obtain the go forward side by side trip temperature monitoring of system temperature value, make computer system when the system temperature value is too high, start heating radiator or increase the output of heating radiator; so that heat energy is dissipated into outside the casing, reach the purpose of protection computer system hardware and operating system.
