Summary of the invention

The purpose of this invention is to provide a kind of also method of running memory testing tool that in BIOS, adds.

The objective of the invention is to realize in the following manner, the program that internal memory is detected the guiding of software and disk and call detection generates disk mirroring in the lump, image file is generated standard I SA/PCI module, module is added mainboard bios, and after mainboard bios refreshed, this mainboard just has the internal memory measuring ability in the POST self check stage, and operation steps is as follows:

1) makes the startup disk that 64K guides Free DOS, keep kernel.sys, command.com;

2) write autoexec.bat file start memscan, and with two document copyings to disk;

3) program of using romos to provide generates disk mirroring, and the module that generates is integrated in the rom file of bios;

4) image file is compiled as standard I SA module, the romos.asm source code that program compiler uses romos to provide is revised the romos.asm source program and is generated the memscan.bin module that meets the ISA standard;

5) bios of backup mainboard generates bios.bin;

6) use cbrom that memscan.bin is integrated into bios.bin;

7) refresh the bios of mainboard;

" time, guarantee to open the Scrolllock lamp and can enter the internal memory trace routine.

Method of the present invention is compared with internal-memory detection method commonly used at present, has the following advantages:

1. by guiding of equipment such as floppy disk, CD-ROM drive, USB flash disk and running memory trace routine;

2. normally enter the in-local system, the internal memory trace routine of reruning;

3. internal memory is taken off, last internal memory machines detects;

4. do not need to cooperate any removable boot media operation trace routine;

5. do not need local hard drive, even the non-disk workstation also can normally be moved;

6. do not need to dismantle main frame;

7. no longer need too much artificial the participation, only need to detect by activate key in the POST stage;

8. do not leave trace routine, cause to detect with anti-virus or artificial destruction not to be inconsistent at local hard drive.

9. make things convenient for the user that this machine internal memory is detected, whether have fault to verify this machine internal memory; And help the PC hardware vendor whether its product to be existed the accurate judgement of memory failure.
