Method for dynamically establishing high-level configuration and power source interface architecture

Abstract

It is a kind of Advanced Configuration and Power Interface (ACPI) structure based on the identification code of hardware that connected with bus when computer system startup. It comprises the following steps: (a) storing multiple ACPI source language that belong to the same type hardware to the basic IO system of computer; (b) when the computer system is under power on self test (POST), detecting the identification code of this kind of hardware that connected with the computer system; (c) loading the unique ASL code of the identification code that detected in step (b) to the storage of the computer system among several ASL codes of this kind of hardware that stored in the basic IO system; but the ASL code of the identification code that not detected in step (b) will not be loaded to the storage of the computer system among the ASL codes of the hardware.

Description

(1) Technical field [0001] The present invention provides a method for establishing an advanced configuration and power management interface architecture, especially a method that can establish an advanced configuration and power management interface architecture based on the identification code of a hardware device connected to a bus when a computer system is turned on . (2) Background technology [0002] In today’s modern information society, computer systems have become one of the indispensable information tools for most people. Regardless of whether it is a desktop personal computer, a notebook personal computer or a server, its operating time is getting higher and higher, and the application level is also increasing. Increasingly widespread. [0003] When the power of the computer system is turned on, the computer system will perform such as power-on test (Power on Self Test, POST), plug-and-play test (plug and play test) according to the Basic Input and Output System (BIOS)...

Problems solved by technology

[0008] However, in the above-mentioned conventional method for establishing an advanced configuration and power management interface architecture, if different computer systems with different peripheral hardware devices are installed on the same connection port, different BIOSes must be written by firmware designers. Notebook computers of different brands and all connected to accelerated graphics port (accelerated graphics port, AGP) display chips must write two different sets of BIOS for these two different display chips, even if other peripherals installed in the computer system The hardware devices are all the same, and the ASL code of the corresponding display chip must be changed in the BIOS, which will consume the cost of writing the firmware program; in addition, the ASL codes of the hardware devices stored in the BIOS of the computer system will be loaded into the memory. And according to the loaded ASL code, the advanced configuration and power management interface table (Advanced Configuration and Power Interface Tables, ACPI Tables) is established in the operating system, so the hardware devices written in the ASL code of the hardware device of the BIOS will all be in the operating system. It is displayed on the advanced configuration and power management interface form. This situation sometimes causes troubles for firmware designers. For example, if the computer system of manufacturer A has device A and the computer system of manufacturer B has device B, and device A and Device B is not connected to the same connection port, so the ASL codes of device A and device B can be written in the same set of BIOS, and the supplier can provide the same set of BIOS for the computer systems of manufacturer A and manufacturer B. However, device B can still be displayed on the advanced configuration and power management interface form of the computer system of manufacturer A, and device A can still be displayed on the advanced configuration and power management interface form of the computer system of manufacturer B, which will cause Vendor A and Vendor B see each other's products appearing on their own computer systems, which causes the problem that hardware devices that should not appear are displayed in the advanced configuration and power management interface form.
