The present invention uses a cover software platform, select configuration can adapt to a plurality of different hardware platforms through simple, it has strengthened the reusability of system, set up under the relatively more sufficient situation at alternative table-drive, all operations is just finished in internal system, need not any external data support, has higher safety assurance, simultaneously, the extensibility of the alternative table-drive system that makes has the expansion interface to unknown hardware.
Description of drawings
Fig. 1 is the partitioned organization figure of the alternative table-drive of the present invention;
Fig. 2 is the process flow diagram of ROMPaq of the present invention;
Fig. 3 is the embodiment operational flowchart.
Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
With X86 Implementation of Embedded System personal computing applianceization, the hardware platform fundamental element is the hardware of ordinary individual's computer, but have several different models or type with kind hardware, the result of permutation and combination has tens of kinds like this, if all design a cover software platform at every kind of combination, obviously development and maintenance cost is too high.
Consult Fig. 1, the present invention is provided with a subregion and does the upgrading reserved area in this embedded system, and this upgrading reserved area does not articulate under default situations.Upgrading keeps an initialized open-ended alternative table-drive in the reserved area, and has deposited the version of the activation bit of scalable just part and descriptive information, scalable application program.
An integrated executable upgrade program that can articulate the upgrading reserved area that is specifically designed to upgrading in system, when needs upgrade hardware or software, the user uses this ROMPaq that user-selected hardware or software are upgraded, if the hardware that upgrades is not have in the alternative table-drive, then log off, directly write brand-new driving file, expand alternative table-drive simultaneously to the system upgrade reserved area.
ROMPaq is a textual interface program, promptly can add the U key with shift key and breathe out after kernel starts.All drivings that need upgrade must be upgraded before it loads.To upgrade the video card driving is example, we send key when starting and preset dual mode when system start-up: a kind of is directly to start to operating system, this kind video card drives and loads, can not upgrade, during normal the operation all is this situation, advanced level user can start to textual interface and manually boot operating system then, and the renewal that video card is driven needs just can carry out in this case.Same, also need before loading, upgrade any other Hardware drive module.Another kind is the exhalation ROMPaq, and this program is articulating the reserved area of upgrading automatically under advanced level user's pattern, and it reads out current obtainable alternative driving tabulation respectively according to the structure of alternative table-drive and tabulation is shown to the user then.
A possible interface is: current video card and the video card that will use, wanting to change a method of driving is: the at first title that drives of definition, path etc., current video card is installed is driven bag, the additional ROMPaq of operation, some hardware need carry out the modification of some key words to corresponding configuration file, ROMPaq is a parameter with current video card, revise the explanation of video card drive arrangements, comprise adding section and revising current use and drive to will be with video card etc., particular hardware has nothing in common with each other, need provide additional ROMPaq respectively, it is identical with manual modification configuration file to finish function.
System restarts the back acquiescence and enters in the normal use, drives to upgrade and finishes.It should be noted that all driving bags should be verified at experiment porch re-uses after errorless.
As shown in Figure 2, ROMPaq can add the exhalation of U key by shift key as being applied and integrated in the system of hiding, its operating process is: carry out proof of identity earlier, if verification is passed through, then articulate the upgrading reserved area and read alternative table-drive, whether inquiry upgrades, select to install AKU by the user then, and carry out necessary configuration file on demand and revise, unloading upgrading reserved area, finish upgrading at last, restart system.If proof of identity can't pass, then direct start-up system.
Be an example below:
1. set up a upgrading reserved partition hda18 in the X86 embedded system, its structure is as follows:
Wherein: BackupDriverList.tab is " an alternative table-drive "
Tnt2_nv.rpm is a driver package, and tnt2_nv.txt drives imprint.
Applicationl.exe is an application program.
The cellular construction of " alternative table-drive " BackupDriverList.tab is as follows:
Typedef?struct?HWInfoUnit
{
Int HWType; // type of hardware such as LX_VGA or APPLICATION
Char HWName[80]; // hardware title such as tnt2_nv or applicationl
char?HWDriverLocat[256]；
The position of // AKU or program is as/Driver/LX_VGA/tnt2_nv.rpm
Or/Exe/Applicationl.exe
}；
2. ROMPaq Update.exe is applied and integrated in the system its operating process such as Fig. 3 as what hide:
(a) carry out proof of identity;
(b) pass through as if verification, then execution in step c; If verification is not passed through, then restart system;
(c) articulate upgrading reserved area and read alternative table-drive, inquiry whether upgrade and display result selective, if upgrading is then installed AKU by the result that the user selects, and carry out necessary configuration file on demand and revise, then do not continue next step if do not upgrade;
