Problems solved by technology

As the functions of the computer increase, the BIOS program will also increase accordingly, and the BIOS program will occupy a larger memory space, which will lead to insufficient memory space to store the Option ROM, resulting in an error in the initialization of the expansion device, so that the computer cannot work normally.

Embodiment Construction

[0009] When the computer is just powered on, it will detect the expansion equipment part, also called Power On Self Test (POST for short). Internal memory, extended memory above 1M, ROM, motherboard, CMOS memory, serial and parallel ports, display card, soft hard disk subsystem and keyboard are tested. Once a problem is found in the self-test, the system will give a prompt message or whistle a warning. During the POST process, the computer will search for expansion devices, such as VGA (Video Graphics Array, Video Graphics Array) cards, etc., and load Option ROM (optional read-only memory program) to the memory for these expansion devices, so as to perform the expansion of the expansion device. initialization.

[0010] see figure 1 In one embodiment of the present invention, a method for optimizing the use of memory can optimize the use of memory during the startup process of a computer BIOS, wherein the memory includes several memory segments, and the method includes the fol...

Abstract

The invention discloses an optimum use method of a memory, which is applied in the process of implementing a BIOS by a computer, wherein a BIOS program is stored in a memory. The method comprises the following steps: finding a program segment of the BIOS program stored in the memory, which does not need to be used in subsequent work; removing the program segment not needing to be used; and maintaining a memory segment originally storing the program segment for a selectable read-only memory (ROM) to use. In the optimum use method of the embodiment of the invention, the program segment space in the memory, which is not used, can be released temporarily to prevent error occurrence caused by insufficient used memory space during loading and implementing the selectable ROM program.

Description

technical field [0001] The invention relates to a method for optimizing the use of memory, in particular to a method for optimizing the use of memory in the BIOS startup process. Background technique [0002] At present, the BIOS (Basic Input / Output System) program in the computer is mainly based on 16 bits (bit), so during the execution of the BIOS, most of the BIOS programs are stored in the memory address range below 1M. In the computer BIOS execution process, the computer will load the Option ROM (optional read-only memory program) on the expansion device for use when the expansion device is initialized, but when the Option ROM is executed, the Option ROM will also be stored in the memory address range below 1MB middle. With the increase of computer functions, the BIOS program will also increase accordingly, and the BIOS program will occupy more memory space, which will lead to insufficient memory space to store the Option ROM, resulting in an error in the initializatio...
