Embodiment
The present invention is that a kind of boot is upgraded recovery system and method thereof, it mainly is the state of confirming boot according to flag value stored in the computer system 10, decide boot whether to upgrade success, perhaps whether need the action of channeling conduct program recovery.
Fig. 1 is a system architecture diagram of the present invention, mainly comprises following plurality of units, is described as follows:
(1) detecting setup unit 30, is core cell of the present invention.Main function is divided into two parts:
(a) start the renewal boot, it produces update signal to loading unit 60 according to user's operational order, (comprising: source end A 81, source end B 82 one of from the source end 80 of computer system 10 outsides by bus 70 by loading unit 60 ... source end N 83) obtaining the boot that will upgrade passes to programmable memory cell 50 and upgrades, this detection setup unit 30 can produce setting signal and give dynamic access storage unit 40 after renewal is finished, and includes predefined flag fixed numbers in the setting signal.
Wherein, update signal also can send dynamic access storage unit 40 to simultaneously, mainly is that the flag value that requirement will originally store is removed, and upgrades the update mode that can reset boot when finishing with box lunch.
(b) start the recovery boot, when BIOS is carried out in computer system 10 starts, can detect the flag value state that is stored in the dynamic access storage unit 40 earlier automatically, when detect finding that comparative result occurs just producing restoring signal when unusual and gives loading unit 60, and equally obtain the boot that to upgrade one of from the source end 80 of computer system 10 outsides by bus 70 and pass to programmable memory cell 50 and recover by loading unit 60, after recovery is finished, also produce setting signal and carry out the flag value setting for dynamic access storage unit 40, recover to carry out the action of BIOS then.
(2) the dynamic access storage unit 40, in order to store flag value, can remove flag value according to update signal, and carry out flag value and set when receiving setting signal.In general, the dynamic access storage unit is random access memory (RAM), the present invention utilizes to divide the block that a pocket is used as storing flag value in RAM, and remaining other RAM block then can be used as when computer system 10 starting up BIOS when programmable memory cell 50 loading boot are started shooting and use.
Wherein, stored flag value can be predefined fixed numbers, and state is normal through renewal or after recovering for the expression boot; Perhaps flag value is being a random number when setting, expression boot abnormal state.
(3) programmable memory cell 50, generally claim programmable read-only memory (prom) again, mainly in order to store the boot of brain system 10 starts of can powering, boot normally exists with the form of compressed image file (compressed image file), when computer system 10 starts BIOS, again boot is sent to aforesaid dynamic access storage unit 40 after compressed image file can being decompressed.
So-called programmable memory cell 50, expression can utilize electronic signal to wipe or ultraviolet ray irradiation such as wipes at mode, the action that data are wherein done removing and write will be stored in, the purpose of upgrading or recovering boot can be realized carrying out by this mode.
(4) loading unit 60, in order to load the boot that will upgrade or recover by bus 70 and to use mode (as: electronic signal erase mode, the ultraviolet ray irradiation erase mode that programmable memory cell is programmed from the end 80 of originating according to update signal or restoring signal ...) boot that will upgrade or recover is written in the programmable memory cell 50.
Source end 80 is often referred to the External memory equipment (as: disc driver, CD-ROM drive, the displacement disc that have boot and be connected with computer system 10 ...); Network (as: INTERNET, the Intranet that also can refer to have boot and be connected with computer system 10 ...) or (as: the PXE System of remote boot system ...) etc.
In fact, the mutual operation between whole computer system 10 and above-mentioned each unit must be undertaken by processing unit 20, and all data transfer and signal communication all are responsible for by processing unit 20, but this is general existing knowledge, so this no longer giving unnecessary details more.
Fig. 2 is that boot of the present invention is upgraded process flow diagram, illustrates how computer system 10 carries out the control of flag value and the renewal of carrying out boot.
At first, when the operation start instruction boot that receives the user is upgraded, by detecting setup unit 30 original stored flag value is removed (step 100) earlier; Then the boot that just will upgrade from the end of source by loading unit 60 loads (step 110) by bus 70; Judge to load whether finish smoothly, boot whether complete (step 120); Deposit in to programmable memory cell 50 if finish (being that boot is complete) smoothly, then reset flag value (step 130) by detecting setup unit 30, the flag value that sets is a pre-set fixed numbers, finishes more new technological process then; If taking place in the renewal process, the interruption situation of non-artificial factor (as: has a power failure, works as machine ...), then the loading procedure of step 110 can't be finished, also not having the flag value of execution in step 130 sets, just directly finish more new technological process, this moment, flag value should be random number (this random number must be different with fixed numbers) arbitrarily.
Fig. 3 is that boot of the present invention is recovered process flow diagram, when computer system 10 starting up BIOS, can read flag value (step 200) by detecting setup unit 30; Relatively judge flag value whether correct and identical with the fixed numbers that had before set (step 210); If carrying out BIOS (step 240), identical then continuation finishes the process step that boot is recovered then, if expression boot inequality has unusually, just need the channeling conduct program recovery this moment, therefore just begin to load the boot (step 220) that to recover from source end 80; Judge whether equally to load and finish (step 230) smoothly; If finish smoothly, then enter step 240 and carry out the process step that follow-up BIOS finishes the boot recovery then, if can not finish smoothly, no required boot or the transmission channel between source end 80 and the computer system 10 have unusually in the end 80 of the present source of expression, therefore this method will be searched other source end 80, so that can finish the work that boot is recovered, when finding next source to hold 80, just get back to step 220 place once again, continue to carry out the related procedure step that loads boot.
Wherein, search the mode of other source end 80 and can carry out in the mode of sequential search (sequential search) according to the basic setting in the computer system 10 usually, this also is general prior art.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; All equivalences that the claim scope is done according to the present invention change and modify, and all should be covered by within the scope of the present invention.
