Method for driving and executing coordination type basic input/output system

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...

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), at the same time point (time point T1), the peripheral access information is sent out, and the BIOS needs to be accessed at the same time. At this time, because the BIOS does not have a coordination mechanism, the corresponding programs may be executed at the same time and different Execution value, for the computer, it may be more unstable in signal transmission and communication due to the existence of multiple execution values ​​at the same time. If the situation is not serious, it may only cause the interruption of the program operation, but if the situation is serious, it may be Causes the entire computer to crash, causing great distress to users
