Embodiment
Fig. 1 is the calcspar according to the reduction of data system shown in one embodiment of the invention.This system comprises reduction of data device 110, storage area 120, working area 130 and the BIOS140 of Basic Input or Output System (BIOS).With present computer system architecture, when computer system was unlocked, BIOS 140 program codes that are stored in the flash memory were carried out to storage area 120 decompressed.And when the setting value of BIOS 140 was modified, the setting value of change then temporarily was stored in the working area 130, with treat subsequent treatment it.
The reduction of data device 110 that present embodiment provided comprises judge module 111, extraction module 113, writing module 115 and recovery module 117.And above-mentioned each module (111-117) for example is to be responsible for the secondary letter formula of difference in functionality with the program code that program language is write, and calls out for the main program code of BIOS 140.So only for convenience of description, do not limit scope of the present invention with this at this.Below promptly introduce the function of reduction of data device 110 each member in detail.
Writing module 115 writes in the BIOS 140 in order to the setting value that will be stored in the working area 130.In other words, when judge module 111 judged that the change of BIOS 140 is determined, 115 of writing modules were searched the setting value after the change in working area 130, afterwards, the setting value after the change is write in the BIOS 140, and become up-to-date setting value.For example writing module 115 table that setting value is write BIOS 140 is gone up an administration interface (Desktop Management Interface is DMI) in the block.
In practical application, the research and development slip-stick artist of BIOS 140 can set up the option of " loading setting value last time " being provided with in the menu of BIOS 140.When the user chooses this option, just drive recovery module 117 to be reduced to the setting value of last BIOS 140.So do not limit the scope of practical application at this.
From another viewpoint, the present invention can summarize a data method of reducing.Fig. 2 is the process flow diagram according to the reduction of data method shown in one embodiment of the invention.Please refer to Fig. 1 and Fig. 2, at first, in step S210, when the setting value of BIOS 140 was modified, extraction module 110 was stored to storage area 120 with BIOS 140 original setting values, and the setting value of change is stored in the working area 130.
With the operation of present BIOS 140, when computer system starting, the user can enter the menu that is provided with of BIOS140 and adjust the setting value of hardware unit (for example operating voltage of central processing unit and frequency of operation).In this time, the setting value that extraction module 113 just will be provided with the respective option in the menu is stored in the working area 130.When the user adjusted the setting value of BIOS 140 in menu is set, judge module 117 judged that the setting value of BIOS 140 is modified, and is stored in the setting value of changing in the working area 130 and drive extraction module 113.
Then, in step S220, when the change of BIOS 140 is determined, then writing module 115 will be stored in a storage area 120 that arrives of setting value backup of change in the working area 130, also setting value can be write in the BIOS 140 simultaneously, and become up-to-date setting value.For instance, when the user BIOS140 the option of selecting " storing and withdraw from (save and exit) " is set in the menu time, then judge module 117 judges that promptly the change of BIOS 140 is determined.Therefore, leave menu is set after, and before restarting computer system, this time setting value of change just is stored in the BIOS 140.
At last, in step S230, after the change of BIOS 140 is determined, be when changing preceding state and will recover BIOS 140, then writing module 115 will be stored in setting value original in the storage area 120 and write back working area 130.For example, when the user be provided with change setting value significantly in the menu after, if when desiring to be reduced into last setting value, recovery module 117 will be searched original setting value in storage area 120, and original setting value covering to working area 130.Afterwards, writing module 115 just writes original setting value in the BIOS 140.Certainly, after the change of BIOS 140 was determined, the user also can load the preset setting values of BIOS 140 in menu is set, for example best (optimal) preset value or failure safe (failsafe) preset value.

Then, in step S320, judge module 117 judges whether the setting value of BIOS 140 is modified.If not, then finish the flow process of storage BIOS 140 setting values; Otherwise when if the setting value of BIOS 140 is modified, shown in step S330, extraction module 111 is stored to the setting value of change in the working area 130.
Then, in step S340, judge module 117 judges whether the change of BIOS 140 is determined.For example, judge module 117 judges whether the option of " store and leave " is performed in menu is set.If not, then finish the flow process of storage BIOS 140 setting values; Otherwise, if, execution in step S350 then, when the option of " store and leave " is performed, after then writing module 115 will be searched the setting value of change in working area 130, the setting value backup of change is a to storage area 120, also setting value can be write in the BIOS 140 simultaneously, and become up-to-date setting value.
On the other hand, Fig. 4 is the process flow diagram according to the reduction BIOS setting value method shown in one embodiment of the invention.Please refer to Fig. 1 and Fig. 4, in step S410, judge module 111 judges whether to recover BIOS140 and is the preceding state of change.For example, at the option of being provided with in the menu of BIOS 140 newly-increased " loading setting value last time ", after changing setting value significantly, the setting value of BIOS 140 is reduced to last setting value of being stored by this option for the user.Therefore, judge by judge module 111 whether the option of " loading setting value last time " is performed, if not, then finish the flow process of reduction BIOS 140 setting values; Otherwise, if execution in step S420 then is to load the setting value of last time.
When judge module 111 judges that will recover the state of BIOS 140 before for change the time, just the user has carried out the option of " loading setting value last time ", in step S420, recovery module 117 is just searched the original setting value of BIOS 140 from storage area 120.
Then, in step S430, recovery module 113 writes back working area 130 with original setting value, to cover the setting value after changing.At this moment, the user just can be according to the setting value of last time storage, and readjusts setting value.Certainly, the user can be reduced to setting value last setting value at any time and readjust when adjusting setting value.In addition, after the setting value after recovery module 113 covers change with original setting value, can drive writing module 115 setting value original in the working area 130 is write in the BI OS140.
In sum, reduction of data method of the present invention and Basic Input or Output System (BIOS) thereof have following advantage at least:
In the setting value of BIOS by after the change significantly, can reduce the setting value of last storage apace, quite convenient.
2. when adjusting the setting value of BIOS, not only can load the preset setting values of BIOS, more can load the setting value of BIOS last time, have more elasticity in the use.
