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
The present invention relates to a kind of internal memory optimization using method, be meant internal memory optimization using method in a kind of BIOS start-up course especially.
Background technology
At present, BIOS in the computing machine (Basic Input/Output System, basic input/output) program is based on 16 (bit), so in the BIOS implementation, the bios program majority is to be stored in the following memory address interval of 1M.And in the computer BIOS implementation, computing machine uses in the time of can loading Option ROM (option ROM program) in order to the extension facility initialization to extension facility, but carry out among the Option ROM, Option ROM can be stored in the following memory address interval of 1MB equally.Along with the increase of computer function, bios program also can increase thereupon, and bios program can take bigger memory headroom, can cause Insufficient memory storage Option ROM like this, causes extension facility initialization mistake, makes the computing machine cisco unity malfunction.
Summary of the invention
In view of above content, the internal memory optimization using method when being necessary to provide a kind of Option of execution ROM.
A kind of internal memory optimization using method is applied in a computing machine and carries out in the BIOS process, and a memory has a bios program, and this method may further comprise the steps: search in the internal memory bios program one and need not the program segment that uses in follow-up work; And remove the program segment that this need not to use, an application heap of former this program segment of storage is kept to an option ROM program use.
Relative prior art, internal memory optimization using method in the embodiment of the present invention, the program segment space that can not be used in the releasing memory that can be temporary transient is to prevent when loading and carry out the option ROM program owing to using the not enough mistake that produces of memory headroom.
Description of drawings
Fig. 1 is the process flow diagram of an internal memory optimization using method in an embodiment of the present invention.
Fig. 2 is the process flow diagram of unloading operation among Fig. 1.
Fig. 3 concerns synoptic diagram for the storage of carrying out this unloading operation.
Embodiment
Computing machine can also be called Power-On Self-Test (Power On SelfTest is called for short POST) to the detection of extension facility part when rigidly connecting energize, function is to check whether computing machine is good, and complete POST self check will comprise to CPU the 640K base memory usually, the exented memory that 1M is above, ROM, mainboard, CMOS memory, serial paralled interface, display card, soft or hard disc subsystem and keyboard are tested, in case pinpoint the problems in self check, system will provide information or whistling warning.In the POST process, computing machine can be searched extension facility, blocks as VGA (Video Graphics Array, Video Graphics Array) etc., and these extension facilities are loaded Option ROM (option ROM program) arrive internal memory, so that carry out the initialization of this extension facility.
See also Fig. 1, a kind of internal memory optimization using method can internally deposit into row optimization use in an embodiment of the present invention in a computer BIOS start-up course, and wherein this internal memory comprises some application heaps, and this method may further comprise the steps:
Step 10: carry out a computer BIOS initialization step, decompression one is used for the bios program of computer initialization from a ROM (ROM (read-only memory)), and this bios program is stored into one first address section of an internal memory, wherein this first address section is the interval, low memory, and the size of this first address section is 1 megabyte;
Step 20: judge whether the program segment in this internal memory bios program need use in follow-up work; As not, then execution in step 42; In this way, then carry out the unloading operation;
Step 42: remove this program segment, and the application heap of former this program segment of storage is kept to follow-up Option ROM use; And
Step 52: load and carry out Option ROM.
Wherein, in step 42, can be as needs to its backup before this program segment is removed, and after step 52, recover, can prevent the follow-up BIOS work of erroneous effects in the step whether the determining program section is used like this in follow-up work, specifically back up and the method recovered can be with reference to the step of this following unloading operation.
As Fig. 2 and shown in Figure 3, this unloading operation specifically may further comprise the steps:
Step 30: search the program segment that needs backup, the program segment that wherein should needs backs up is included in needs the program segment that uses in the follow-up BIOS operational process;
Step 44: this program segment of unloading one is different from second address section of this first address section or dumps in another storage medium in this internal memory, and the application heap of former this program segment of storage kept to follow-up Option ROM uses; Wherein this unloading action can be decomposed into and duplicate this program segment earlier in this second address section or storage medium, removes program segment corresponding in this first address then, and wherein this second address section is the high memory interval;
Step 54: load and carry out Option ROM; And
Step 64: recover in this second address section or this storage medium in program segment to this first address section so that this bios program can continue execution.
Use in this method at the present embodiment internal memory optimization, save as a RAM (random access storage device) in this.This program segment is the program element that has specific function in the bios program.When judging whether this program segment can use in follow-up work, can judge the program segment of all bios programs by judgment mode one by one, to carry out corresponding operation respectively.
The program segment space that can not be used in the releasing memory that this internal memory optimization using method can be temporary transient in the embodiments of the present invention, so that the usage space of Option ROM to be provided to greatest extent, to prevent when loading and carry out Option ROM owing to using the not enough mistake that produces of memory headroom.
