Abstract
The present invention relates to a computer memory detection method. It contains utilizing BIOS obtaining specific memory message and displaying on operation interface, through operation interface receiving detected memory selection, according to selecting executing specific memory accessing detection, according to memory accessing detection result, outputting detection result to operation interface.
Description
Technical field
The present invention relates to a kind of computer internal-memory detection method, particularly a kind of being applied on the computer line, the optionally method that detects individually of specified memory slot.
Background technology
Along with the progress of industrial and commercial prosperity with science and technology, the use of various computing machines, micro computer is general day by day, and in exist and occupy epochmaking status in aforementioned counter, the micro computer structure, as long as there is mistake slightly to occur among the internal memory, just the wrong or omission because of the data generation most probably, and cause the user to perplex greatly.
In today industrialized country, produce the electronics industry that internal memory has become a hi-tech and intensive capital.In this kind industry, in order to reduce cost, the automatic system operation of consistentization is indispensable; In addition, it is also very worthy to detect the employed machinery and equipment of internal memory, and the starting and ending address that may just detect full memory or user's specified memory tests, and also can't be confirmed to be the problem of the internal memory on which memory bank immediately if pinpoint the problems in test process; In this case, which bar internal memory is orientation problem appear on if desired, then the full memory bar must be unloaded, and plugs each bar internal memory then respectively and tests and could realize.So not only increase artificial operational ton (plugging memory bar repeatedly), but also will repeat repeatedly to move same test procedure, influenced production efficiency, increased the control difficulty of flow process, do not met the requirement of batch production on production.
The development of server platform is towards the trend of the many memory modules of multiple masters, is necessary that therefore the method that proposes accurately to detect at indivedual internal memories improves the problem of present existence.
Summary of the invention
Technical matters to be solved by this invention provide a kind of can be fast, accurate which memory bar in-problem method whether on the test computer, its manually-operated amount is few, does not influence production efficiency and control difficulty.
Internal-memory detection method of the present invention, it finds all north bridge equipment by traversal PCI equipment, backs up the configuration information of each north bridge equipment, and according to the size of device numbering these equipment is arranged.Be shown in operation interface for information about by what visit Basic Input or Output System (BIOS) (BIOS) obtained each internal memory.Wherein this information comprises two attribute informations, and first is used to distinguish the affiliated north bridge equipment of each memory bank (DIMM), and the call number of this memory bank on affiliated north bridge equipment.Another then is used to write down the sizes values of the internal memory of being installed on each memory bank.
Can determine north bridge equipment under the memory bank of current internal memory place according to first property value, get in touch between each north bridge equipment and memory bank group, to set up, add the attribute information of memory size, so actual internal memory number of being inserted then comes into plain view on the memory bank group that each north bridge equipment is connected.According to this contact, when on the interface, selecting different north bridge equipment, can dynamically realize the variation of memory bank group, promptly select which north bridge equipment, the memory bank group information on this north bridge equipment of then corresponding demonstration.
By operation interface, accept internal memory to be detected and choose.Index value according to the memory bank on selected north bridge equipment on the interface and selected north bridge equipment, add the sizes values of each internal memory that has obtained, can calculate the starting and ending position of the internal memory on the test memory slot of wanting, in this scope, internally deposit into the row test then.Internal memory is write logical value and reads logical value and compare,, then represent this internal memory existing problems if write set logical value and to read logical value inconsistent.According to the memory access testing result, the output testing result is in operation interface.
Utilize said method so that just internal memory to be measured is inserted on each memory bank simultaneously with all when test begins, each internal memory of appointment is tested need not to repeat to plug under the situation of internal memory, can accurately determine to damage the position of internal memory, improve the efficient of system greatly, liberated yield-power.
Description of drawings
Fig. 1 is the process flow diagram of internal-memory detection method of the present invention.
Wherein, Reference numeral:
Step 100 finds all north bridges by PCI equipment
Step 101 obtains all memory attribute information by Bios
Step 102 is set up getting in touch between north bridge and the DIMM group by first attribute information
Step 103 obtains the memory size value by second attribute information
Step 104 shows the pairing DIMM group of each north bridge information
Step 105 is according to selecting to calculate the memory test position
Step 106 detects internal memory according to test position
Step 107 is found mistake
Step 108 shows error message
Embodiment
With reference to figure 1 as can be known, carry out internal memory and detect, at first will find all north bridge equipment (step 100), the number of record bridge device by PCI equipment.Back up the configuration information (comprising VendorID, Device ID, Bus Number, Device Number, Function Number) of each north bridge equipment, and these equipment are sorted according to the size of device numbering (Device Number).Obtain (step 101) for information about of each internal memory by visit Basic Input or Output System (BIOS) (BIOS).Comprise two attribute informations in this information, first attribute information is used to distinguish the affiliated north bridge equipment of each memory bank, and the call number of this memory bank on affiliated north bridge equipment.Second attribute information then is used to write down the sizes values of the internal memory of being installed on each memory bank.Can determine north bridge equipment under the current internal memory according to the first attribute information value, set up get in touch (step 102) between north bridge and the memory bank group, add second attribute information (step 103), so when the user selects north bridge to be tested, can show this north bridge pairing memory bank group information (step 104).According to the index value of the memory bank of user on selected north bridge equipment on the interface and selected north bridge equipment and the sizes values of acquired internal memory, calculate the internal memory starting and ending position (step 105) on the test memory slot of wanting.According to the starting and ending position, in this scope, internally deposit into row test (step 106).Write set logical value to internal memory, compare with the logical value of reading again, if inconsistent then think this internal memory existing problems (step 107).According to the memory access testing result, the output testing result is in operation interface (step 108).
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
