Embodiment Construction

[0054] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] refer to figure 1 , which shows a flow chart of steps of an embodiment of a method for identifying a device information storage location according to the present invention, which may specifically include the following steps:

[0056] Step 101, the CPU reads configuration information in the BIOS;

[0057] The Basic Input Output System (BIOS) is an industry-standard firmware interface whose main function is to provide the computer with the lowest and most direct hardware setting and control. In addition, BIOS also provides some system parameters to the operating system.

[0058] For the display controller integrated in the bridge chip, due to the different design of the board, if the correct configuration information of the...

Abstract

The embodiment of the invention provides an equipment information storage position identification method and device which are applied to a display control system, the display control system comprisesa central processing unit (CPU), a graphics processing unit (GPU), a basic input / output system (BIOS) and a specific memory, and the method comprises the steps: enabling the CPU to read configurationinformation in the BIOS; if the configuration information in the BIOS meets a preset rule, initializing the GPU by using the configuration information in the BIOS; if the configuration information inthe BIOS does not meet the preset rule, reading the configuration information in the specific memory; and if the configuration information in the specific memory meets the preset rule, initializing the GPU by using the configuration information in the specific memory. According to the embodiment of the invention, the storage position of the board card configuration information is determined by judging whether the BIOS and the data in the specific memory meet the preset rule or not, so that the storage position of the board card configuration information can be effectively identified, and the software adaptation problem caused by the fact that the storage position of the board card display related configuration information is not fixed is solved.

Description

technical field [0001] The present invention relates to the technical field of identification, in particular to a method for identifying storage locations of equipment information and a device for identifying storage locations of equipment information. Background technique [0002] The board card is a printed circuit board, referred to as PCB board, which has a ferrule when it is produced, and can be inserted into the slot of the main circuit board (main board) of the computer to control the operation of hardware, such as monitors, acquisition cards and other equipment. , after installing the driver, the corresponding hardware functions can be realized. [0003] The size of the board configuration information is uncertain. In some boards, it can be directly placed in the BIOS firmware, and in some boards, it needs to be stored in a specific memory. [0004] For the display controller integrated in the bridge, due to the different design of the board, if the correct configur...
