Embodiment approach

[0024] Please continue to refer figure 2 , the preferred embodiment of the graphics card BIOS loading method of the present invention comprises the following steps:

[0025] S1: start the DOS operating system of the motherboard 12, call and execute the loading program in the hard disk 14.

[0026] S2: Obtain the range of the original graphics card BIOS in the execution range of the graphics card BIOS in the memory 124. Wherein, the interval occupied by the graphics card BIOS is generally much smaller than the execution interval of the graphics card BIOS, for example, the interval occupied by the graphics card BIOS may be 4KB. When the interval occupied by the graphics card BIOS is smaller than the execution interval of the graphics card BIOS, the remaining intervals within the execution interval of the graphics card BIOS are sometimes occupied by other application programs in the computer system 10. In the invention, the codes of these application programs are defined as ad...

Abstract

The invention discloses a method for loading a display card BIOS, which comprises the following steps of: starting a DOS operating system and executing a loading program; acquiring an interval range occupied by the primary display card BIOS; storing an extra program code to a register; setting an execution interval of the display card BIOS in a readable-writable state; storing to-be-loaded data of the display card BIOS into the execution interval of the display card BIOS; executing an initialization program of the display card BIOS; acquiring an interval range occupied by a to-be-loaded display card BIOS; judging whether the interval range occupied by the to-be-loaded display card BIOS is greater than the interval range occupied by the primary display card BIOS; if so, displaying prompt information through a display; otherwise, rewriting the extra program code and a setting the execution interval of the display card BIOS in a read-only state. The method for loading the display card BIOS can conveniently and quickly load the new display card BIOS.

Description

technical field [0001] The invention relates to a loading method, in particular to a method for loading a BIOS (Basic Input Output System, Basic Input Output System) of a graphics card. Background technique [0002] The graphics card BIOS on the graphics card is also called "VGA BIOS". It plays the same role as the system BIOS on the computer motherboard. It also executes some basic functions and stores the control program between the graphics card chip and the driver. It also stores information such as the graphics card model, specifications, manufacturer, and delivery time, and initializes the graphics card when it is turned on. [0003] During the research and development of computer motherboards, sometimes it is necessary to frequently refresh the graphics card BIOS on the graphics card, usually in the following two situations: [0004] 1. For the onboard graphics card, generally the graphics card BIOS is included in the system BIOS, and then burned into the motherboard...
