Description
(1) technical field
The present invention is relevant with a kind of Basic Input or Output System (BIOS) (BIOS) (basic input output system) element, particularly about a kind of can be when damage takes place in the content of BIOS, be written into back-up BIOS by main Storage Media, and the method and the relative program design that make system start shooting and to repair automatically.
(2) background technology
Along with Information technology develops fast, add the facility and the progress of network communication, PC has become one of electrical home appliances of each family's indispensability.In general computer, can on motherboard, install a BIOS element, with as the communication interface between computer hardware and the operating system, and be stored in programmed instruction in the BIOS storer by execution, and the detection of carrying out the CPU inside and outside is set, is started dynamic RAM (DRAM), chipset and the peripheral device that links computer are done value just sets, drive soft, Hard Disk Drive at last, and being written into such as operating systems such as DOS, Windows, Linux.After start guiding action was finished, BIOS then can carry out support, the co-ordination of thin portion, handled the execution action that peripheral device is linked up to help operating system or application program.No matter be present pandemic notebook computer or desktop computer, all must under the condition of correct execution BIOS function, just boot program be can successfully carry out, and the initial setting and the test of hardware when starting shooting finished, but guaranteeing the hardware operate as normal, and enter in the required operating system.
When the record in inspection maintenance computer service station, be not difficult to find the situation that major part can't normal boot-strap, often because its BIOS element or flash memory (Flash ROM) break down and cause.And these problems except few partly be because the element material is damaged institute causes, major part all can be by the Maintenance Engineer with special frock appliance or program, and the data recovery of BIOS is finished reparation.Yet, when running into the situation that to start shooting, often there are not proper implements or relevant knowledge to repair one on the way and have only to select to send by oneself for the consumer.Like this, except having influenced its operate as normal of consumer, various tangible and invisible maintenance costs have also been increased.
In order to solve this kind problem, in relevant BIOS technical field, have and use two ROM of BIOS (BIOS ROM) simultaneously or the ways such as capabilities double of ROM (read-only memory) (ROM).For example, just disclosed the method for a kind of automated back-up BIOS in No. 446864 patent of bulletin, wherein by increasing the capacity of BIOS ROM, multiple objective programming goes out one and prestores the space that can recover the bios program sign indicating number.When booting computer opens beginning BIOS element failure, just be written into back-up BIOS automatically and damage the situation that the BIOS content breaks down computer to prevent the improper operation of consumer.Yet use this kind method,, can cause the rising of BIOS element cost like this owing to need significantly increase the capacity of BIOS ROM.
In addition, in No. 428748 patent of bulletin, a kind of two groups of BIOS circuit elements design of on motherboard, installing have simultaneously been disclosed.By logical circuit and judging circuit, when a BIOS element is damaged because of misoperation therein, can start another group BIOS immediately by automatic judgement of circuit and start shooting.Identical with aforementioned patent, use this kind design need on motherboard, install two groups of independently BIOS elements and relevant decision circuitry, so also can cause the increase of cost of manufacture.
In No. 454145 patent of bulletin, disclose a kind of may command and replaced the interface switching of system bios element on the motherboard.By with this interface switching be used for the extra memory of back-up BIOS procedure code and be installed on the motherboard, can be according to the working condition of BIOS element, right of priority switched to the storer of backup when whether decision will start shooting, so that solve the situation that the BIOS element breaks down.Yet this kind situation also need be installed extra storer and interface switching on motherboard, so also do not meet the cost consideration requirement.
Cause the cost of manufacture rising except the extra part of needs installing, storer, interface or increase memory span, traditional BIOS standby system also lacks the cordiality on using for consumers.Typical B IOS backup recovers design all needs the user by the screen menu processing or carry out the replacement of entity component.In typical design, whether behind BIOS element boot failure, screen-picture can switch to an operation menu, require the user to determine to start shooting with the bios program sign indicating number of backup, or carry out BIOS and return the action of depositing, to attempt repairing the BIOS element that damages.Yet, for most consumer, the command function on its understanding menu, and make suitable selection according to relevant indication, often cause sizable puzzlement.
What is more, in many existing BIOS backup designs and require the user that the switch bar on the motherboard (jumper) is switched, and the BIOS element of backup had an effect.Or load onto the BIOS element that the appended part of manufacturer starts backup at the slot of computer casing.This kind mode is extremely difficult especially for consumers in general, and Da Bufen consumer can deliver to computer each maintenance station like this, in order to avoid expend meaningless mental and physical efforts on the affairs of getting rid of computer glitch.Yet for manufacturer, just need to spend more manpower and do reparation and the maintenance of BIOS, thereby increased various tangible, invisible costs like this for the client.

(5) embodiment
Please refer to Fig. 1, this figure shows according to the bios program structure 10 that can carry out repair action automatically provided by the present invention.This bios program structure 10 is stored in the storer of BIOS element, for example leaves in by in quickflashing (Flash) or the EEPROM (Electrically Erasable Programmable Read Only Memo) ROM of BIOS that element constituted (BIOS ROM) such as (EEPROM).When the user carried out boot action, system just can be by reading bios program sign indicating number, the start of the line correlation of going forward side by side and test procedure in the BIOS storer.And when damage taking place, can finish boot action, in relevant Storage Media, also can deposit one group of BIOS stand-by program in order to frequently needs by the bios program sign indicating number that other Storage Media (such as the computer hard disc) is written into backup at the BIOS memory content.
Identical with traditional BIOS design, typical startup block (boot block) 12 and function program (function code) module 14 have been comprised in this bios program code structure 10, in starting block 12, mainly deposit the beginning program that opens of booting computer, and can be to being stored in the content in the BIOS storer, carry out correctness and check and reduce maintenance.Generally speaking, be arranged in this procedure code that starts block 12 and have special hardware or software protection, avoid changing arbitrarily or writing.For example, can provide anti-write protection to starting block 12, avoid unexpected write activity by the IC chip in the BIOS storer.
As for functional program module 14, then can be used to deposit function service routine and gunzip through overcompression.As shown in Figure 1, this partly functional program module 14 comprised decompression module (Decompressmodule) 16, start selftest module (POST module) 18, with resident program module (Run-Time) 20.Wherein, decompression module 16 is mainly used to depositing in the action that decompresses of function service routine in the BIOS storer, and whether check the BIOS compressed content automatically correct.Start selftest module 18 is then deposited through the BIOS of overcompression start self test program, after decompressing by decompression module 16, can carry out self test program to computer hardware, software and peripheral device.In addition, 20 of resident program modules are deposited through the BIOS of overcompression functional mode/resident program sign indicating number, provide relevant function service equally after carrying out gunzip by decompression module 16.
It should be noted that in order to make bios program have the function of automatic reparation, in described BIOS storer, increased by an automatic repairing module 22, be used to detect the practice condition of described functional program module 14.When the bios program sign indicating number can't be finished boot program, automatic repairing module 22 is start again, and by being written into and carrying out BIOS stand-by program sign indicating number on the Storage Media, so that smooth initiating task system.Still please refer to Fig. 1, in embodiments of the present invention, this automatic repairing module 22 can comprise measuring ability 24, repair function 26 and comparing function 28.Wherein, measuring ability 24 can detect described decompression module 16, start selftest module 18, with the decompression situation of resident program module 20, to judge whether wrong generation.
When gunzip made a mistake, repair function 26 can carry out described boot program again automatically, and was written into and is carried out the bios program sign indicating number of backup by other Storage Media.But after confirming the boot action of BIOS stand-by program sign indicating number successful execution, repair function 26 can return the new burning of BIOS stand-by program code weight in the BIOS storer.In addition, it is new and old with the main program version that leaves in the BIOS storer that comparing function 28 can be checked BIOS stand-by program sign indicating number, if main bios program sign indicating number can be finished start smoothly, and when having the version than backup updating, then main bios program sign indicating number can be deposited to Storage Media, to make BIOS stand-by program sign indicating number again.
What particularly point out is in order to prevent the improper damage of generation in operation of described automatic repairing module 22, also it can be integrated in the startup block 12 with anti-write protection.Please refer to Fig. 2, wherein can in starting block 12, increase the relative program of measuring ability 24, repair function 26 and comparing function 28.That is, whole automatic repairing module 22 embedded start in the blocks 12, make its can detect, repair, with relatively wait function.In such cases, detect wrong method automatically, except the summation inspection (checksum) of commonly using, and can when carrying out gunzip, BIOS check the size and the error-detecting code (CRC of correlation module; Cyclic redundancy check).In addition, when BIOS can't normally finish the start selftest when (POST), also be considered as making a mistake and detected.Certainly, according to the demand in the design, also can select to detect, repair, embed with the part of comparing function and start block 12, other partly then is positioned in the startup block 12 BIOS storer in addition.
Please refer to Fig. 3, this figure shows correlation function among this embodiment, modules configured relation.Wherein, the startup block of BIOS 12 can be checked the main bios program sign indicating number that be stored in the flash memory, and BIOS backup version new and old in it and the Storage Media relatively.If, main bios program sign indicating number makes a mistake and can't be written into operating system smoothly, then starting block 12 can start shooting again and enable the BIOS stand-by program of depositing in the Storage Media, and after finishing boot action smoothly and being written into operating system, the bios program sign indicating number burning of backup is returned in the BIOS flash memory.As for when the bios program sign indicating number in the flash memory is written into operating system smoothly and has newer version, then this bios program sign indicating number is backed up in the Storage Media, and make new BIOS stand-by program sign indicating number.
Then please refer to Fig. 4, this figure shows the related procedure of utilizing described automatic repairing module 22 to detect, repair and back up.Behind system boot 40, measuring ability 24 can be checked the signal (flag) 42 of whether before having set up the BIOS memory content to damage in advance, if there is damage then directly to enter automatic maintenance pattern; Otherwise whether the content of then checking decompression module 16 correct (step 44).If gunzip is incorrect, then select to enter automatic maintenance pattern; Otherwise, then carry out and separate this condensing routine, start selftest module 18 is decompressed to set memory location (step 46).
In the process of carrying out described gunzip, if find any mistake, module, the length after the decompression or the check code and the record that for example can not find the desire decompression do not conform to or the like, promptly are considered as the BIOS memory content and damage.At this moment, set up a BIOS memory content to damage signal earlier and force system's start shooting again (step 48).In case restart the startup block 12 of BIOS, measuring ability 24 just can enter automatic maintenance pattern according to the damage signal of being set up.Otherwise when start selftest module is decompressed into set position, and the result is correct, then can begin to carry out the start selftest (step 50) of BIOS.Then, carry out the gunzip (step 52) of resident program module 20 equally, and whether the result who detects after decompressing is normal.When detecting wrong the generation, then carry out described step 48, set up signal and start again.What specify is that in the selftest process of start, the condensing routine in the start selftest module can be carried out according to need repeatedly.And in the process of carrying out that decompresses each time, measuring ability 24 all can carry out described content and damage detection.
Damage signal or decompress when wrong as for detecting, just can enter automatic maintenance pattern when measuring ability 24.At this moment, repair function 26 can be written into (step 54) in the primary memory at the BIOS stand-by program sign indicating number of main Storage Media with backup, and replaces the execution of BIOS memory program sign indicating number with the stand-by program that is written into.In preferred embodiment, loaded BIOS stand-by program sign indicating number can comprise described decompression module, start selftest module, with three parts of resident program module.Therefore, repair function 26 can be carried out the gunzip (step 56) of backup, and the start selftest module and the resident program module that are written into are carried out gunzip.
If whole BIOS start test event is all correctly finished, and executed then judges whether to enter in the automatic maintenance pattern when being written into operating system.If entered in the automatic maintenance pattern, the content of then originally depositing in the BIOS storer is obviously damaged to some extent, and this moment, repair function 26 can be with the BIOS stand-by program sign indicating number in the Storage Media, and burning is returned in the BIOS storer (step 58) again.Otherwise, if the BIOS system does not enter automatic maintenance pattern, show that then procedure code in the BIOS storer does not make a mistake or damages, then the program version of more present burning in the BIOS storer and be stored in new and old (step 60) of the backup version of main Storage Media.If at present the version in the BIOS storer is newer,, backup in the specific reserved area of main Storage Media (step 62) automatic maintenance usefulness when impaired then automatically with the content of present burning in order to the BIOS memory content at the BIOS storer.Like this, though the BIOS storer because hardware problem can't maintenance, but the content of backup on main Storage Media still can allow system's normal boot-strap.Then, carry out operating system loader (step 64), and control is given operating system (step 66).
Like this, owing to BIOS stand-by program sign indicating number loaded in step 54 is the normal BIOS memory program sign indicating number that is backuped at last on the main Storage Media.Therefore when the BIOS memory content was damaged, the content of stand-by program sign indicating number can replace the BIOS memory content of having damaged, and made the system still can normal boot-strap.And carry out the suitable stage of BIOS oneself start test when the procedure code that is written into, when system environments has been enough to carry out the burning BIOS memory program, if determining system is in automatic maintenance pattern, then can start BIOS memory burn program, the stand-by program code weight that is written into is newly burnt back the BIOS storer.Under this kind situation,, still can continue to carry out BIOS selftest and operating system loader, and make system can keep normal use no matter whether its burning result is successful.
Compared to the practice of conventional art, design provided by the present invention and function have considerable advantage:
(1) because according to design of the present invention, can promptly automatically back up correct bios program sign indicating number at ordinary times, therefore when damage takes place in the BIOS storer, the bios program of once starting shooting successfully before reading in the Storage Media by other automatically to be backed up, and reach the effect that renewal is at any time backed up.Like this, the bios program sign indicating number of backup can reflect the present behaviour in service of system more accurately.
(2) take place owing to can automatically detecting the BIOS mistake in the present invention, and automatically reply action, once had problem to take place for the user is almost imperceptible like this, also can not have influence on the user and work normally.
(3) because the failure problems of most BIOS all can be solved by mode of the present invention, can significantly reduce the chance that computer is sent company's maintenance back to like this, and save maintenance cost down significantly, and promote the toughness of product.
(4) in addition,, so can not increase extra cost yet, do a little changes and get final product and only need to write at the framework of BIOS and program because utilize mode of the present invention not need extra spare part fully.
Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
