Computer system, and method for accessing display identification data and control system thereof

Abstract

A computer system, and a method for accessing display identification data and a control system thereof are disclosed, wherein the computer system is used for connection with a display device in which the display identification data is not recorded, and comprises a nonvolatile storage unit and a basic output / input system, wherein the nonvolatile storage unit records a control code for indicating the display device; the basic output / input system further comprises a video basic output / input system and a display control module; the video basic output / input system records a plurality of identification codes and each identification code corresponds to a piece of display identification data; and the display control module is used for reading the control code and comparing the plurality of identification codes when the computer system is started up, thus obtaining an identification code in accordance with the control code, wherein the display control module loads the display identification data corresponding to the identification code in accordance with the control code into a main storage unit of the computer system. The method is capable of enabling the computer system to provide correct display identification data effect according to the display device connected with the computer system.

Description

technical field [0001] The present invention relates to a computer system, in particular to a computer system for connecting a display device which does not record display identification data. Background technique [0002] Most computer monitors record relevant identification information by themselves, so they can be connected to different computer systems at will to output and present data, pictures or videos processed by the computer system, which can be called a general-purpose display device. [0003] like figure 1 As shown, the general-purpose display device 10 includes a storage unit 100 for recording the display identification data applicable to the display device 10, including its model, length and width of the display range, screen update frequency and other data. Commonly used storage unit 100 is Electronically Erasable Programmable Read Only Memory (EEPROM). When the computer system 12 is started, the basic input / output system 126 executes the boot loader, and r...

Problems solved by technology

At this time, in order to match the different display devices to be matched with the computer system, it is necessary to issue multiple different versions of display identification data and burn them into the designated computer system respectively. In addition to the burden and trouble of data version maintenance , which also causes the inconvenience of additional control work for the operators on the production line and the increase of production costs
