Embodiment
Now please with reference to accompanying drawing, displaying wherein is only in order to explain the preferred embodiments of the present invention, but not limited to its category.
Fig. 1 is the process flow diagram according to the method for the backup of memory data of the embodiment of the invention.Please,, carry out the initialization internal memory at step S10 with reference to Fig. 1.In addition; Can repeat the action of three times reset (reset) to the internal memory on the mainboard; This step can produce an initializes configuration information; This initializes configuration information comprises memory reference code host data (memory reference code host data, MRC host data), and after reset flag is removed, carries out next step; Then, at step S20, initializes configuration information is write the nonvolatile memory of a Basic Input or Output System (BIOS) (Basic Input Output System abbreviates BIOS as).The nonvolatile memory of BIOS is meant after electric current is turned off, the computer memory that stored data can not disappear.The nonvolatile memory of BIOS can be flash memory (flash memory) or ROM (read-only memory) (read only memory), so the nonvolatile memory of the BIOS in the present embodiment can preserve initializes configuration information, like the MRC host data.Then, at step S30, remove a memory block of the nonvolatile memory of BIOS.Then, at step S40, but check memory block and judge whether memory block is write state.At last, if but write state gets into step S50, initial configuration data are write memory block.Present embodiment can reach the effect of backup of memory data; BIOS start oneself after helping detects, in the environment of DOS or Windows, can do analysis to the initialize memory configuration information, therefore makes things convenient for the user to check the relevant configuration information of storer.
Fig. 2 is the process flow diagram according to the method for the backup of memory data of another embodiment of the present invention.Please with reference to Fig. 2, present embodiment is similar to the process step of Fig. 1.The step 20 that initializes configuration information is write the nonvolatile memory of BIOS also comprises step S210.In step S210, can check whether be the nonvolatile memory of the BIOS that supports of mainboard.In the checking process of step S210, can also check that whether storage arrangement is the nonvolatile memory of the BIOS that supports of system board, and look-up table can write down the trade name and the model of the flash memory that mainboard supports according to a look-up table.If the check result of differentiating then gets into step S30 for being, begin to remove the memory block of the nonvolatile memory of BIOS, otherwise then because of the nonvolatile memory that does not have BIOS gets into step S260, the end back-up job.
At step S30, remove the memory block of the nonvolatile memory of BIOS.Then carry out step S40, but check memory block and judge whether memory block is write state.
The inspection memory block also judges that whether memory block is but that the step 40 of write state can also comprise step S240.In the checking process of step S240, can also check whether the data of memory block are the 0XFF of 16 systems.If the check result of differentiating then gets into step S50 for being, begin initial configuration data are write memory block, otherwise then come back to step S30.
What deserves to be mentioned is; After the step S30 that gets back to " memory block of removing the nonvolatile memory of BIOS ", get into the step S240 of " whether the data of inspection memory block are the 0XFF of 16 systems " once more, exceed to carry out five loops; If five times differentiation result is not still for the time; Then get into step S260, finish back-up job, on time or cause suspension (hang) phenomenon avoids waste.
At step S50, with an initial configuration writing data into memory block.Then, carry out step S250, whether the data that write of inspection memory block are the initial configuration data.
In the checking process of step S250, can also check the differentiation result.If the check result of differentiating is then accomplished back-up job, otherwise is then come back to step S50 for being.
Moreover; After the step S50 that gets back to " with an initial configuration writing data into memory block ", get into the step S250 of " whether the data that write of inspection memory block are the initial configuration data " once more, exceed to carry out five loops; If five times differentiation result is not still for the time; Then get into step S260, finish back-up job, on time or cause the suspension phenomenon avoids waste.
Even under the situation of power down, being stored in the data of the nonvolatile memory the inside of BIOS, can not lose by the nonvolatile memory of the BIOS of present embodiment; (Random Access Memory RAM) does not do under the situation of special protection after the startup selftest (Power On Self Test is called for short POST) of BIOS is accomplished, and the data of RAM the inside will be lost unlike RAS.
The embodiment of the invention is through the operation to the nonvolatile memory of BIOS, promptly through the relevant working storage of read-write chip group, the whole mapping of this structural information of MRC host data is kept at the fixed space of certain section reservation of the nonvolatile memory of BIOS.In addition, in the nonvolatile memory of removing and write BIOS, can do the trial of a loop five times, if surpass five times still operation failure will withdraw from, do not cause the suspension phenomenon so can not cause closed loop.Certainly the number of times of loop is as limit, and it is big more that loop operate successful probability more at most, still can waste the time of start like this.
In sum; The method of backup of memory data of the present invention is because of adopting the technology that initializes configuration information is write the nonvolatile memory of BIOS; Therefore the environment such as self-detection, DOS or Windows of starting shooting at BIOS can be done analysis to the initialize memory configuration information, and make things convenient for the user to check the relevant configuration information of storer.
Though the present invention discloses as above with embodiment; But it is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; Can change arbitrarily or be equal to replacement, so protection scope of the present invention should be as the criterion with the scope that the application's claim is defined.
