Adopt the refreshing/recovering method of the present embodiment when recovering the initialization data of electronic equipment or refresh, because described second memory cell has been the hardware that electronic equipment carries, therefore do not need the external device such as CD-ROM drive or floppy disk is installed again, can directly refresh the initialization data of electronic equipment, and when the first corrupted data in the first memory cell, only need start this refreshing/restore funcitons, set up control unit and the data transmission channel between the first memory cell and the second memory cell, by the read-write operation of electronic equipment internal hardware, the recovery of the first data in the first memory cell can be realized, and do not need the process of the first memory cell being carried out to the complexity such as burning again, thus make the refreshing/recovery process of initialization data convenient, simply, fast.
More than describe and describe the basic thought of the embodiment of the present invention, below with the refreshing of the bios program of computer/revert to example, the method for the embodiment of the present invention is described in detail.
In a computer, first memory cell is BIOS chip (as BIOS Flash), first data are bios program, bios program is stored in BIOS chip, also bios program is stored in second memory cell in the present embodiment, under normal circumstances, BIOS chip is generally connected with south bridge ICH or PCH of computer by spi bus, PCH or ICH is connected with the CPU of computer by north bridge.
Under normal circumstances, when starting shooting, bios program carries out power-on self-test (Power On Self Test to each equipment of computer-internal, be called for short POST), after POST process completes, the hardware of computer is initialized, and be directed to DOS or other operating system, thus complete the startup of computer, afterwards by the various functions of operating system computer for controlling.If because some reason bios program is damaged, then cannot complete the processes such as power-on self-test, initialization, boot, make a mistake in each process, computer all can be reported to the police by different way.
Be embedded controller EC below with control unit be example, illustrate in the present embodiment and run into bios program damage or the processing mode under needing refresh case, now, the second memory cell can be ECFlash on hardware, and the structure of each unit of the computer in the present embodiment as shown in Figure 2.
When BIOS damage maybe needs to refresh, system sends instruction and refreshes/recover the operational order of bios program to EC, after EC obtains this operational order, be connected with EC Flash with BIOS chip by spi bus or other channel, disconnect the connection of BIOS chip and PCH or ICH simultaneously, to ensure that follow-up work is carried out smoothly from interference, and then the data transmission path between EC and the BIOS chip set up and EC Flash, wherein, EC is connected with PCH or ICH by LPC interface, to carry out other work, EC reads the bios program stored in EC Flash afterwards, and by the data transmission path between three, by the bios program write BIOS chip in EC Flash, with original bios program in alternative BIOS chip, thus complete refreshing or the recovery of original bios program in BIOS chip.
It should be noted that, the producing method that instruction refreshes/recover the operational order of bios program has multiple, can be in start process, because of BIOS damage cannot carry out normal boot program time, system alarm also produces this operational order simultaneously, automatically this operational order is sent to EC afterwards by system; Also can be in the power-offstate, trigger default operating key by user to produce, EC obtains described operational order by the described default operating key of monitoring, and off-mode described in the present embodiment refers to that the key of computer does not start, but EC maintains the state of electricity; Also can be under open state, system obtains by network or alternate manner the information that bios program has new version, thus producing this operational order etc., the producing method of this operational order includes but not limited to above-mentioned three kinds of modes, and the present embodiment does not do concrete restriction to this.
Wherein, the mode automatically being produced the operational order of refreshing/recovery bios program by system can be divided into two kinds of situations, and one is produce when bios program damages, and two is need carry out more producing under news at bios program.If the former, when user does not know that bios program damages, its producing method can be system alarm in start process, and produces this operational order simultaneously, thus triggers the action of EC; If the latter, the producing method of this operational order can have multiple, if system is once confirm that bios program has the information of renewal, or stores the bios program of renewal in EC Flash, and then triggers the refreshing of bios program.
Below be only with the refreshing of the bios program in computer/revert to example, the method of the present embodiment is illustrated, known from the above description, when bios program damages, adopt the method for the present embodiment directly can realize the refreshing to bios program by computer itself, and do not need storage tool to external world to carry out the complicated operation such as burning again, and then make the refreshing of bios program/resume work quicker, easy and effectively.
It will be appreciated by those skilled in the art that, the method of the present embodiment can be applicable to the refreshing/recovery of computer initialization program, also refreshing/the recovery of mobile phone, PDA or other electronic equipment initialize routine can be applied to, and, the hardware of described control unit, the first memory cell and the second memory cell is selected and connected mode includes but not limited to above disclosed content, as long as configure accordingly according to the actual conditions of different electronic equipments.
