[Prior Art] Some important information on the computer, such as computer manufacturer information, product identification, and asset labeling, are burned on the multi-layer printed circuit board. Generally, the user obtains or sets it through the system BIOS provided by the manufacturer. In addition, I/O for self-diagnostic test programs, system bootloaders, system setup programs, and main input/output (1/〇) devices programmed on a Read Only Memory (ROM) chip. BIOS information such as drivers and interrupt service routines provide the lowest level, most direct hardware control for the computer to ensure that all computer circuits are available before the operating code is run. The BIOS is part of the motherboard, so it is sometimes referred to as firmware. 〇 Generally, the conditions for obtaining, editing, and testing BIOS information are as follows: 1. Read or edit server information groups such as asset tags and product identifiers. The information in the product is identified as the product attribute; 2. The system management BIOS (SMBIO) function and the test non-volatile random access memory (N〇nv〇latUe Random Access Memory, NVRAM) are good or bad; Get or modify the program burned in the BIOS ROM. Currently, the main 1291636 method for obtaining and editing the above BI〇s content is implemented by the __, 纟MDisk Qperating _, (4) BIOS interrupt calling service, but this method has the following disadvantages: l Currently in Linux/ Under Windows system, you can't directly modify the server's m〇s information. 'If you want to modify it, you must restart the system to enter the BI〇s to perform the modification' and then restart the system and return to the Linux/Wind〇ws towel. If it is found that the modified value is not the expected value, or if the new value is to be modified, the above process needs to be repeated, and each modification-time data is restarted at least twice. Therefore, _ households are not only cumbersome and costly to sell; 2) since Linux is not real; I: Fu, does not support BIOS interrupt steel service, can not transplant the program to this method to Li · Next. In addition, this method is not feasible under Windows systems. That is, the BIOS content acquisition and editing of the multi-platform operating system cannot be realized; 3. If the BI0S content is acquired and edited under the Linux/Windows system through the port mode, the program implementation method in the Linux/Windows and Dos environment may be caused. The inconsistency is not easy to maintain, which leads to serious consequences of some important information being erased in the BIOS data area. 4. The traditional method relies too much on hardware and Biogj. Once the hardware and BIOS are upgraded, it is likely to appear. The program needs to be re-maintained, and the specific interrupt operation method needs to be provided by the BIOS manufacturer, so it brings some inconvenience to the user; 5. Whether the BIOS interrupt call or the port operation, the programming interface is complicated and difficult to maintain; To implement the BIOS interrupt service program under Dos, the user needs to know the modified BIOS data segment, modify the type of interrupt service that should be used, its function number/sub-function number, and the use of the corresponding AX/CX/SI/DI registers. . Βΐ〇§Interface complex 'Non-professionals are difficult to fully grasp the setting method; 7·If the programming appears 1291636 error, it is easy to cause important BIOS information loss when misoperation, which will bring unpredictable damage to the system. At the same time, even a small mistake will bring great difficulties and inconvenience to the debugging work of the program; 8. There is no test item specifically mapped to the NVRAM area of the system by the BIOS. Due to the importance of the NVRAM area of the system, Directly affect the integrity and security of the server BIOS information storage. SUMMARY OF THE INVENTION In view of the above problems, it is a primary object of the present invention to provide a method and a secret for acquiring and editing basic input/output system (BIOS) information, thereby solving the limitations or disadvantages of the prior art. / The method and system for acquiring and editing the basic input and output information disclosed in the present invention can directly perform the lion simplification on the bi〇s information without restarting the currently operating operating system _ simplification , Gorgeization and humanization 0 π material revealed by the basic input output system to take the money and money τ steps: the image of the transmission (four) unified information system non-easy New Zealand random access (10) (NVRAM) area towel. : The mapping content of the NVRAM area is stored as a first document; the first document is modified according to the modification information of the second output system, and the second document is generated - the content of the second text is restored to the content of the text slot (4) corresponding to the VRA job area The corresponding position of the domain to the basic input and output system 2 = this input and output system information.

"图!图" is a block diagram of the acquisition and editing system of the deleted information of the present invention. As shown in the figure, the ugly information acquisition and editing system disclosed in the present invention is applied to the acquisition and editing of the electric station 12 Basic round robin. A basic input output system (deleted) is the most critical component of a computer system for processing input and output of poor materials. It is a set of programs that are burned onto a computer motherboard to provide the lowest level and most direct computer. The hardware control is used to store the self-test = type, system bootloader, system setup program and main input output d/ο) _1 / () drive _ type and love service transfer task. When the computer is running, the system reads from the start address of the BIOS ROM and runs the bi〇s program. The BIOS program first checks each internal device to test the hard connectivity of the computer' and loads the necessary operation code to allow the brain to perform the required tasks. To be precise, the BIOS is between the computer hardware and the software program. One, the converter said that it is the interface (it is only - health), responsible for solving the hardware: (4) the demand '幷 according to the software to the hardware operation requirements. Bl〇s program code storage 11 1291636 • There are such as Erasable Programmable Read-only Memory (EPROM), Flash ROM, Nonvolatile Random Access Memory (Nonvolatile Random Access Memory, NVRAM) or other digital information storage devices. The BIOS > acquisition and editing system 1 includes a mapping module μ, a backup module 18, an editing module 28, and a recovery module 26. First, the mapping module 14 stores the BIOS information stored on the computer motherboard 12, such as the program code written on the R〇M• chip of the computer motherboard 2, and some important information about the server. It is mapped into the system NVRAM area 16. Non-volatile random access memory (NVRAM) is more and more widely used because it retains the characteristics of data that cannot be lost even after power is turned off. Then, the backup module 18 searches for the BIOS information mapped to the system NVRAM area 16, and extracts and stores all the mapped content in the area as a first document, that is, the backup document 20, and the document format is not limited. The name of the file is NVRAM.bak. In order to realize the information reading of the system NVRAM area 16 under the Dos/Windows/Linux system, different underlying drivers can be called under different operating systems. The driver implementation reads the system NVRAM area 16 by means of a page, first writes the page of the selected operation to the NVRAM page register (PAGE) and then reads the system NVRAM area 16 from the NVRAM data storage crying (NVDAT). News. The NVPAGE/NVDAT can be operated in the driving mode by using the 1/〇 mode or the storage mode, thereby obtaining the information in the NVRAM area 16. ... first 12 Ϊ 291636 Then, the editing module 28 modifies the backup slot 20 according to the Bios modification information input by the user, and further generates a second document, that is, a new document 24, which is named NVRAM.new. Here, the editing module 28 includes an information search module 30', a cyclic redundancy code verification module 32, an information reassembly module 34, an NVRAM document editing module 36, and a comparison module 38, which are combined below.

Figure 4 is a schematic diagram of the poor information group of the BIOS information acquisition and editing system embodiment. It can be seen from the figure that the data storage in BI〇s follows a certain rule 'starting with the keyword corresponding to each data segment. As shown in the figure, the primary key ends with a specific separator as a keyword. The keyword followed by the substring, that is, the subkey, and the position of the substring, the information content of the substring, the length of the substring, and finally the end of the substring with a specific separator. The figure shows a primary key CQHLIPI/, corresponding to, server asset test"; four sub-keywords, CQHLS1, CQHLS2, CQHLS3 and CQHLS4, respectively, and / / server asset test " information page expanded four The group information corresponds to the information. After the information search module is parsed 30, the corresponding information about the server name, the server asset tag, the server basic operating system, and the four sub-keys of other tests are shown in Figure 4. Shown. In this embodiment, the server asset test information is mapped to the system NVRAM area 16, and is stored as a binary file by the backup module 18. For the format of the backup text 20, see "figure 5". "Picture 5" is a schematic diagram of the document of the BI〇s information acquisition and the application of the flat system, and the information group content, data address and information of the information on the /" A piece of data corresponding to each piece of information in the information group. For example, the character area 5 〇 indicates the main key // cqhlipi/, which is represented by the character area 524C 50 49 48 51 43, in the form of a binary document, 14 1291636 The character area 54 〃(η, denoted as the main _word__6) is the separator of the sub-keys after the sub-key;:::56 length, followed by the substring_容, the string between the substrings • Now return to “3rd picture”, cyclic redundancy code verification mode (4); =: the location of the bit 'and then according to the backup in the _: the original value of the original Wei redundancy code, in the user input needs After the modified (4), the production, - new cyclic redundancy code value. The traditional method to obtain the redundant code value in _ is more complicated than the thief, and the algorithm looks at the value of the code and the total amount of data in a specific area of the ' The content of each sub-data segment, the offset position of each sub-investment, the separator between the data segments, etc. Closely related, each - under-performed = BJOS interrupt service program to modify BK) S-f ship interior material, the order of other data areas is also changed, and the money-calculation is known to the outside world, and upgraded in Bi〇s In this case, this algorithm may also be mixed. The information in the previous day's job photo #前·$ data area is the area in which it is located, the offset, the order, the separator between the data segments, etc., and only the required modification_content is handled accordingly. This affects only the number of changes in the redundancy code value of the Yuhuan ring. It is only necessary to analyze the difference between the new BIOS funding capacity and the old capital rating. In addition, the information reorganization module 34 may modify the plurality of information groups in the information search module 30 according to the twisted (10) input by the user, and replace the corresponding information in the information group according to the modification information. The NVRAM document editing module 36 is a new document 24 by backing up the document 2, the plurality of information groups in the information search module 30, and the new utah ring redundancy value 15 1291636. First, the NVRAM document editing module 36 copies the new document 24 according to the backup document 20, and then clears the information related to the BIOS data area in the new document 24, and then edits the new document according to the information recorded in the information group, and further adds a new cyclic redundancy code. The value is written back to the corresponding location in the new document, and finally the correctness of the content in the new document 24 is verified based on the backup document 2, the information group information, and the new cyclic redundancy code value. The "figure 5" and the "figure 6" are embodiments of the BIOS information acquisition and editing system according to the present invention, wherein "figure 5" is an embodiment of the BIOS information acquisition and editing system of the present invention. The first textual diagram, "FIG. 6" is a schematic diagram of the second document of the embodiment of the BIOS information acquisition and editing system of the present invention. When the content of the first line of the "server asset tag" information on the "server asset test" shown in Figure 5, ie, the character area of the sub-key 2 information content 58 333333333333〃 Instead, AAAAAA% and the content of the second line, that is, the character area 6〇 of the information content of the sub-key 2 is changed to null, wherein the binary data content corresponding to the character areas 58, 60 is the character area 62. Then, the new document 24 generated by the document editing module 36 is as shown in the "figure 6", and the modified content corresponding to the character area 64 is obtained. In addition, the editing module 28 further includes a comparison module 38 for comparing different versions of BIOS information, for example, comparing two NVRam products specified by the user, or a certain NVRAM document and current BIOS information specified by the user. Find out the faults of each of the 12 1291636 versions of the BIOS information. The user can also specify the area or keyword to be compared. The editing module 28 is the core module of the present invention, which implements the information module of the M〇s information module. The self-riding cable, the function of the shift amount and the self-_ring redundancy code value verification, ensures the security of the BI0S information modification operation. When modifying the brain information, if the protection mechanism of the BI_S towel's _zone_no secret modification θBIOS itself is modified, the important information is emptied and even more serious consequences. The recovery module 26 disclosed in the above description restores the content of the new document % to the location of the system to sharply delete the Q domain, and the purpose of modifying the BI〇S f message. Because Μ _ write also f to follow - set the law, and the system NVRAM medium rtr 'single operation on a byte may affect other positions of the recovery module 1 round Na Xi, so restore NVRAM __ will be new _Back to the system ringing. At the same time, ΐ ί avoids the adverse effects of a single byte operation alone.
