Embodiment
For making the purpose, technical solutions and advantages of the present invention express clearlyer, the present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Main thought of the present invention is the BIOS calling module to be set in BIOS in advance, applied function module is set in hard disk.The BIOS calling module is embedded among the BIOS, is used to call applied function module; Applied function module is positioned at hard disk, is used to carry out concrete application.Because applied function module is arranged in hard disk rather than BIOS, so those of ordinary skill can directly develop or revise applied function module, does not need directly in BIOS, to make amendment, thereby can improve the dirigibility of BIOS exploitation.
Fig. 1 is the process flow diagram of expanded BIOS function of the present invention.The BIOS calling module is set in BIOS at first in advance, applied function module is set in hard disk.The BIOS calling module is embedded among the BIOS, is used to call applied function module; Applied function module is positioned at hard disk, is used to carry out concrete application.Can in PM, PS, SM or SS, applied function module be set here.Preferably, in the protection subregion of hard disk, applied function module is set, to avoid destroying applied function module owing to user's regular job.
As shown in Figure 1, this method is further comprising the steps of:
After step 101:BIOS finishes hardware detection and initialization, BIOS operation BIOS calling module.
After BIOS starts, just begin to carry out the BIOS boot system and detect (POST) flow process.In the BIOSPOST flow process, BIOS is detection hardware and finish various initial work at first.After having detected hardware and having finished various initial work, the BIOS operation is embedded into BIOS calling module wherein.
Step 102:BIOS calling module calls applied function module.
After the BIOS calling module was moved, the BIOS calling module just began to call applied function module.Here, the BIOS calling module at first need find applied function module in hard disk, just can call applied function module then.The BIOS calling module is searched applied function module in hard disk mode can have multiple, can set the mode of searching applied function module in advance in the BIOS calling module.The mode of searching applied function module in hard disk includes, but are not limited to: the BIOS calling module can all hard disks of circulation searching, to search applied function module; The BIOS calling module also can only be searched specific hard disk, to search applied function module; The BIOS calling module can also only be searched detected first hard disk, to search applied function module.If applied function module is to be kept in the protection subregion of hard disk, then at first needs to open the protection subregion of hard disk, and then in the protection subregion, seek applied function module.In the protection subregion, can seek applied function module by modes such as the address that specifies Offsets, special marking, partition tables.If hard disk is not protected subregion, then directly in hard disk, seek applied function module.After finding applied function module, the BIOS calling module then just calls applied function module.
Step 103: applied function module is carried out and is used.
After applied function module is called, just carry out concrete application.These application include, but are not limited to: opening operation system, executive operating system are recovered standby functions, the operation multimedia is appreciated concrete application such as application.And, if desired applied function module is made amendment, can directly on hard disk, make amendment, need in BIOS, not make amendment.
When comprising in the applied function module when being no less than one application, in advance that these application in the applied function module are corresponding with user's input information.The user at first the BIOS in step 101 finish after hardware detection and the initialization, input information before the operation BIOS calling module in step 101, BIOS is kept at internal memory with this input information, read internal memory at step 103 applied function module then, obtain user's input information, and carry out corresponding concrete application according to user's input information.
The present invention will be described in more detail with a concrete example below.
On a lot of computing machines Windows operating system is installed all, and other operating systems or application except that Windows also can be installed on many computing machines, to provide value added service to the user.For example: supposing to be equipped with on the computing machine with Linux is the multimedia appreciation application of operating system.Simultaneously, this computing machine also is equipped with the application that is used for operating system is backed up recovery, with backup user's operating system commonly used and data or carry out system recovery after user's operating system commonly used is damaged.(SuSE) Linux OS and this backup recover to use and all are installed in the protected location of hard disk; invisible under the normal condition to the user; to guarantee that farthest linux system and this backup recover the safety of using, avoid damaging linux system and this backup and recover to use because of user's regular job.
Based on Fig. 1, Fig. 2 is the process flow diagram of expanded BIOS function according to an embodiment of the invention.The BIOS calling module be set at first in advance, applied function module is set, and setting in advance the user, to push button that F1 represents to start with Linux be that the multimedia of operating system appreciate to be used that the F2 that pushes button represents to start backup and recovers to use in hard disk in BIOS.Wherein, the BIOS calling module is embedded among the BIOS, is used to call applied function module; Applied function module is positioned at hard disk, is used to carry out concrete application, comprises carrying out application and the backup recovery application that multimedia is appreciated.As shown in Figure 2, further comprising the steps of:
Step 201: hardware detection and initialization, and prepare the BIOS parameter list.
BIOS at first finishes hardware detection and various initialization after starting.BIOS prepares parameter list simultaneously, and deposits parameter list in internal memory.Comprise in the parameter list that needed various hardware informations are used in startup and the user is used to select the concrete user's input information of using.Preferably, the key information pressed for the user of this user's input information.Start the needed hardware information of application and can comprise hard disk port, hard disk size, CD-ROM drive type, mouse type etc.
Step 202:BIOS operation is embedded into BIOS calling module wherein.
Step 203:BIOS calling module judges whether to find applied function module, if then execution in step 204 and subsequent step thereof, otherwise execution in step 208 and finishing.
Here, the BIOS calling module can be searched for applied function module in many ways.For example: the BIOS calling module can all hard disks of circulation searching, to search applied function module; The BIOS calling module also can only be searched the hard disk of formulation, to search applied function module; The BIOS calling module can also only be searched detected first hard disk, to search applied function module.If applied function module is to be kept in the protection subregion of hard disk, then at first needs to open the protection subregion of hard disk, and seek applied function module in the subregion, if do not protect subregion then directly in hard disk, seek applied function module in protection.
Step 204:BIOS calling module calls applied function module.
After finding applied function module, BIOS just calls applied function module.
Step 205: applied function module reads the BIOS parameter list.
Applied function module at first obtains the BIOS parameter list from internal memory, and obtains user's input information and start and use needed hardware information.
Step 206: applied function module has judged whether and the corresponding application of user's input information that according to user's input information if having then execution in step 207 and end, otherwise execution in step 208 also finishes.
Step 207: applied function module is carried out and the corresponding application of user's input information.
Applied function module can be carried out the application that the user selectes according to hardware information that obtains and key information.That suppose that the user presses is button F1, and then the BIOS calling module at first starts (SuSE) Linux OS, and moving this then is that the multimedia of operating system is appreciated and being used with Linux; That suppose that the user presses is button F2, and then the BIOS calling module starts backup and recovers to use.
Step 208: return BIOS POST flow process.
Generally speaking, carry out flow process of the present invention, can carry out various application smoothly to guarantee applied function module in the final stage of BIOS POST flow process.But, not necessarily need when the operation of the performed application of applied function module under the situation of complete execution BIOS POST flow process, as long as can guarantee that the function of applied function module is enough to realize, also can in the pilot process of carrying out BIOS POST flow process, carry out the present invention.
In the above process, BIOS prepares the BIOS parameter list in step 201, and the BIOS calling module starts concrete application according to the BIOS parameter list in step 207.Optionally, according to concrete application demand, if do not need application is selected, and start to use and also not need special parameter, then BIOS also can not prepare parameter list in step 201.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
