Problems solved by technology

[0003] Because the BIOS detects and starts the program, it often happens that the peripheral control unit (chip set) responsible for controlling different interface devices will access some programs in the BIOS at the same time. At this time, a complete coordination mechanism has not been established in the BIOS. Therefore, it often causes abnormalities in the operation of the BIOS, and even affects all executing programs abnormally, which in turn causes the computer to stop.
[0004] by figure 1 For example, this figure is a schematic diagram of the structure of a general computer BIOS system in the known technology when it is running. control unit)...

Embodiment Construction

[0029] based on the following figure 2 , image 3 , illustrating a preferred embodiment of the present invention.

[0030] The present invention is a kind of coordinated BIOS driver execution method, which is used in the previous BIOS (please refer to figure 1 ), that is, a section of coordination program code is added in the system boot image module 100, and then the computer system can be booted and started by this program code, and the received peripheral access information that needs to access the BIOS at the same time is coordinated. The system operation structure can refer to figure 2 , as for its main method to run the step process, it will pass image 3 to illustrate.

[0031] The method operation part of the present invention is described below, please refer to image 3 In fact, the entire coordinated BIOS driver execution method of the present invention must be established under the premise that the coordinating program code starts to execute, that is, the ent...

Abstract

A section of coordination type program code is added to well-known system starting up mapping BIOS. In starting up period executed by system, the said section of code carries out coordinating operation for periphery access information of BIOS, which is needed to access synchronously. The main technical measure is that the periphery program, which is needed to access synchronously, and possible to cause BIOS to execute abnormally, or failure, is copied and transferred to corresponding memory of periphery control unit (chip set). Thus, periphery program is driving executed in the said memory. The method lowers possibility of generating confliction so as to reach purpose of coordinating execution.

Description

technical field [0001] The present invention relates to a method for running a system startup initialization program, in particular to a method for coordinating the simultaneous access to peripheral access information of a Basic Input Output System (BIOS) during the system boot image program stage method. Background technique [0002] Generally speaking, when the computer is turned on, it must do some startup management programs, the so-called system boot image program, or the so-called BIOS. For example: some self-test programs (Power-On Self-Test, POST) when the computer is started, as well as low-end settings such as disk drives, keyboards, and screens, and provide some interfaces for controlling various interface devices connected to the computer. Related software support. [0003] Because the BIOS detects and starts the program, it often happens that the peripheral control unit (chip set) responsible for controlling different interface devices will access some program...
