Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent.
As shown in FIG. 1, the method for updating BIOS by entering the Recovery through the hot key, entering the Recovery interface through the keyboard combination hot key, and then selecting to update BIOS on the Recovery interface is suitable for the product using AMI codebase.
The method for entering Recovery to update BIOS through keyboard combination key comprises the following steps:
S1, in the starting process, a system responds to a hot key instruction operated by a user, and a restarting action is completed according to the setting of a global flag bit;
S2, judging to enter a Recovery mode according to the zone bit in the step S1, detecting a BIOS Bin file in the U disk in the process, and performing security comparison;
S3, finishing the drawing work of the menu corresponding to the Recovery page according to the security comparison result in the step S2, if the comparison is successful, drawing an operationally updated Recovery interface, wherein the drawing result is shown in FIG. 3, and if the comparison is failed, drawing a Recovery interface which cannot be operationally updated, and the drawing result is shown in FIG. 4;
s4, selecting a menu bar which is continuously updated in an operable update Recovery interface, namely a 'processed WITH FLASH update' menu, and carrying out BIOS update, wherein the update effect diagram is shown in figure 1.
The step S1 specifically includes:
S11, adding a response function of a specified hot key in a power-on POST code, detecting whether the specified hot key is pressed in the POST process, and setting a CMOS (complementary metal oxide semiconductor) flag bit (0 x 52) to a specified value (0 xBC) if the specified hot key is detected to be pressed;
s12, when the fact that the designated hot key is pressed is detected, a task is needed to be completed, namely a restarting instruction is issued to the system, and the system is restarted.
The hot key is designated as a combined key of a control key and a function key, for example, ctrl+f10, other function keys can be combined with the control key Ctrl, if necessary, a Shift key Shift or Alt key can be used in combination with the function key to be used as a hot key for making, and setting can be performed as required.
When BIOS is updated, a combined hot key such as Ctrl+F10 is pressed, so that the BIOS can enter a Recovery mode to perform updating operation, and the threshold used by a user is reduced; meanwhile, the CMOS zone bit (0 x 52) is set to the appointed value (0 xBC) so that the system can judge whether to enter the Recovery mode or not conveniently, and a specific parameter value is used as a judging standard, namely, the CMOS zone bit corresponds to the appointed value and enters the Recovery mode, otherwise, the CMOS zone bit does not enter, so that the operation difficulty is reduced, the system judgment is more accurate, and the updating and using risks of a terminal user are reduced.
The step S2 specifically comprises the following steps:
S21, judging whether the system enters a Recovery mode according to the CMOS flag bit (0 x 52), if the value corresponding to the CMOS flag bit (0 x 52) is a specified value (0 xBC), entering the Recovery mode, otherwise, not entering the Recovery mode;
s22, if the Recovery mode is entered in the step S21, detecting whether the U disk equipment exists in the Recovery starting process, if so, executing the step S23, and if not, directly returning to FALSE;
s23, detecting whether a BIOS bin file with a designated name exists in the U packing catalog, if so, executing a step S24, and if not, directly returning to FALSE;
s24, detecting whether a PROJECT_TAG mark in the BIOS Bin file is consistent with the system, if so, returning to TRUE, otherwise, returning to FALSE.
The system performs multi-layer verification on the updated files and conditions in the Recovery process, namely, the verification processes of whether the U disk equipment exists, whether the BIOS bin files with the designated names exist, whether the PROJECT_TAG marks are consistent with the system and the like are performed, and the updating selection is performed for the client after all the updated files are correct, so that the operation difficulty of the client is reduced, the client does not need to understand and know the updated files of each layer, the system is more suitable for vast users, the computer level requirements of the client are not too professional, the accurate upgrading operation can be completed, the safety of the system updating is ensured, and the operation risk of the terminal user is reduced.
The step S3 specifically includes:
s31, if the final return value of the step S24 is TRUE, drawing an operable updated Recovery page and menu content, wherein the drawing result is shown in FIG. 3;
S32, if the final return value of the step S24 is FALSE, drawing the updated Recovery page and menu content which cannot be operated, and drawing the result is shown in FIG. 4.
The system directly presents the result interface to the terminal client according to the judgment result, and the client can clearly judge the state of the updating process according to the content in the interface, so that the client can select and operate, the operation process is more foolproof, and the client is simpler and easier to understand.
As shown in fig. 3, in step S4, when the BIOS is updated, the specified area of the BIOS is updated according to the selection of the user, wherein the NVRAM and the BOOT BLOCK area are selectively updatable areas, and the MAIN BLOCK area is a default updated area.
The client can select the updating mode according to own updating requirements, and after the previous steps, the updating selection space is provided for the client under the condition of ensuring the updating accuracy, and the updating flexibility is improved under the condition of ensuring the safety.
According to the updating method, the hot key response is increased, the machine is enabled to enter the Recovery mode according to the corresponding result of the hot key, in the process of entering the Recovery mode, the BIOS bin files which can be used for updating in the U disk are detected and checked, and the corresponding updating menu is drawn for the user after the updating is confirmed to be available, so that the updating safety is ensured.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
