It is as shown in Figure 1 a kind of flow chart of data processing method in the embodiment of the present invention, this method is set using an electronics
In standby, which has complete operating system and basic input-output system BIOS, this method comprises:
S101, basic input-output system BIOS are obtained to indicate that electronic equipment accesses electronic equipment by first code
In file first instruction；
S102 transfers the first code being stored in advance in BIOS memory space, and execute the first generation based on the first instruction
File in code access electronic equipment hard disk.
Specifically, the file operation of user in the electronic device is all based under the normal mode of operating system and carries out,
User is recorded in some storage region of the electronic equipment operation of file at this time, but based under operating system
The operation note stored under normal mode can be accessed by other electronic equipments, result in operation of the user to file operation in this way
Record security is poor.
Therefore, in embodiments of the present invention, the New Technology File System (English: New of mainboard BIOS is modified first
Technology File System, referred to as: NTFS) code, guarantee to access by BIOS with subsequent user in this way
File in the hard disk of electronic equipment.
Specifically, in embodiments of the present invention, which modifies the NTFS code of BIOS first, so that after
It is continuous file access to be carried out by BIOS.Secondly, also needing an independent memory space to protect in the electronic equipment
User is deposited to the operational motion of file, that is, the code of access disk file.
In the electronic device, the distribution of memory space is indicated Memory Controller Hub by BIOS to complete, that is to say, that BIOS
Specifically how the memory headroom in electronic equipment should be distributed to determine, then to Memory Controller Hub one instruction, to indicate
Memory Controller Hub is allocated in deterministic fashion.The memory headroom in electronic equipment is assigned in Memory Controller Hub
Later, the configuring condition of memory headroom is sent to BIOS by the Memory Controller Hub in the electronic equipment, and BIOS can know at this time
The configuring condition of road current memory.
After BIOS determines the configuring condition of memory, which will be to operating system (Operating
System, abbreviation OS) configuring condition of memory headroom is reported, under normal circumstances, BIOS can configure all memory headrooms
Situation is reported to OS, and allows all memory headrooms for OS, is all visible, so all reading institutes can be used in OS
There is the content saved in memory headroom.
But in embodiments of the present invention, when BIOS reports the configuring condition of memory headroom to OS, which will
It is invisible that a part of memory headroom is configured to OS, that is to say, that the content stored in the partial memory space, OS can not be to them
The operation for being read out or being written, for OS, which is inaccessible memory headroom.
Further, in embodiments of the present invention, in order to enable BIOS can timely call the first generation being stored in advance
Code, therefore, in embodiments of the present invention, which can be stored in the firmware of BIOS, it may be assumed that in the ROM of BIOS.Here
First code included at least access disk file code and/or be at least one application program code.
Specifically, when needing through BIOS to access file, the visit of file is carried out by the code in BIOS
It asks, thus needs to transfer out the execution code in ROM, such as first code, the first code also need to be written to BIOS
In a preconfigured memory headroom, for OS, which is sightless, so OS can not be to memory sky
Between access, ensure that in this way by BIOS carry out disk file access safety.
For example, in embodiments of the present invention, there are an operating system OS, basic input and output in the electronic equipment
System bios, there are one memory headrooms.
Firstly, the NTFS code in modification BIOS, so that BIOS is able to access that the file in hard disk, hard disk here includes
Disk either solid state hard disk (English: Solid State Drives, referred to as: SSD).
System Management Mode (English: System Management Mode, abbreviation: SMM) is entered in the electronic equipment
When, that is to say, that when the electronic equipment is switched under SMM mode, the user to the access of fixed disk file all directly by BIOS come
It realizes, and carrys out the file in access hard disk not by file system.
Certainly, when electronic equipment enters SMM mode, the electronic equipment is to by BIOS/firmware pre-stored first
Code is written in pre-configured memory headroom, which cannot see for OS, is being written to this
After in memory headroom, which will transfer out the first code in the memory headroom, then visiting by first code
Ask the file in hard disk, first code here is exactly file read-write driving, it may be assumed that accesses the code of disk file.
By above-mentioned explanation, at System Management Mode SMM, user can lead to the file access in the electronic equipment
BIOS is crossed to realize, so that user is all based on the code in BIOS to the operation of file to carry out, so that electronics
OS in equipment can not know the operating process to file of the user, so that the operation of file more has completeness.
Further, in order to enable electronic equipment can according to the demand of user between normal mode and SMM mode phase
Mutually switching, therefore, electronic equipment are additionally provided with trigger device or the triggering software, the trigger device and triggering of a hardware
Software can be triggered to switch to electronic equipment by the first preassigned pattern access file system and be visited by the second preassigned pattern
Ask the switching command of file system.
Therefore, which can detect whether to exist in real time accesses file by the first preassigned pattern for electronic equipment
System switches to the switching command that file system is accessed by the second preassigned pattern, the first preassigned pattern here be CPU just
Normal operating mode, the second preassigned pattern are System Management Mode.Under the first preassigned pattern, it is by under OS that user, which accesses file,
File system carry out.And under the second preassigned pattern, it is progress of being got off by SMM mode that user, which accesses file,.
Certainly, after detecting the switching command, which will switch to hard by the access of the second preassigned pattern
File in disk.The mode for accessing file at this time is exactly to be realized by BIOS.
What needs to be explained here is that SMM is a standard architecture spy unified to all Intel processors
Property, this mode realizes that the specified function of platform provides a kind of transparent mechanism for OS, be activated when external SMM interruption or
When advanced programming interrupt control unit receives an interruption, processor will go into SMM.In the smm, when preservation is currently running
When the entire context of program, processor is switched to the address space of a separation, and then SMM specified code is perhaps transparent
Execution.When returning from SMM, processor be will be returned to by the state before system break.
Therefore, in embodiments of the present invention, under SMM mode, electronic equipment will stop the currently performed execution journey of CPU
Sequence.That is, in user by BIOS to carry out file access when, the electronic equipment will generate one interruption, the interruption use
Stop current execution program to trigger CPU.
Certainly, after the CPU in the electronic equipment stops executing current execution program, which will be real-time
Detection accesses whether the file in electronic equipment is completed by first code, if should be accessed in electronic equipment by first code
The operation of file when not completing, the CPU in the electronic equipment will continue to stop the execution of current execution program；If passing through
When the operation of file in first code access electronic equipment has been completed, the CPU in the electronic equipment, which will restart, currently to be held
Capable program, that is, once terminated by the process that first code accesses file, the CPU in the electronic equipment will restart
The execution program terminated before.It can guarantee in this way so that the file operation that user carries out under SMM mode more has peace
Quan Xing.
In addition, it should also be noted that, in embodiments of the present invention, in the memory headroom that OS cannot be identified, in addition to can
Except code to save access hard disk file, application program can also be saved, such as the code of some test function programs,
Can be tested process by BIOS in this way, so that checking procedure is more safe.
Such as some safety certificates can be stored in the memory headroom, when receiving a certain electronic equipment either
When the checking command that a certain network server is sent, which can first switch to SMM mode, and then electronic equipment can
The safety certificate in the memory headroom can be transferred out by BIOS, to terminate when program performed by CUP currently hold at this time
Capable program.BIOS will execute the checking procedure of safety certificate at this time, after the verification of safety certificate is completed, the electronic equipment
The program being terminated in CPU will be restarted.The safety check of safety certificate is ensured that in this way, not only can be mentioned
Efficiency is risen, and the verification safety of safety certificate can also be promoted.
In embodiments of the present invention, when user needs to carry out the operation of file under safer environment, the electronics
Equipment carries out the access of file by being switched under SMM mode, under the SMM mode, user passes through the operation of file
BIOS is realized, so that OS is sightless to the operation of file, therefore improve the safety of file operation.
