Abstract
The invention discloses the methods that a kind of capsule file of nested type is updated to BIOS, comprising the following steps: step 1: carrying out nested integration to multiple capsule files；Step 2: when brushing into BIOS, SMI further parses capsule document analysis if discovery capsule file is that format is nested, after all having parsed, the file that parsing obtains is summarized and keeps in unified memory region, and is uniformly brushed in BIOS ROM.
Description
Technical field
The present invention relates to computer hardware field, in particular to the capsule file of a kind of nested type is updated to BIOS
Method.
Background technique
Existing platform updates BIOS by SMM using capsule mode, and binary block of the safety with respect to legacy is write
Entering has revolutionary raising, but its elastic relative deficiency, and capsule is brushed can only be with the data of one or more continuums into mode
It is written, to rewrite these regions again, it is necessary to it is executed again after exiting application, it cannot can be with such as binary block writing mode
It is rewritten in or else environment that application is exited in the region of original write-in.
Summary of the invention
To solve defect existing in the prior art, the purpose of the present invention is design a kind of capsule file of nested type
To the method that BIOS updates, elastic writing mode is increased on the basis of not breach security.
The invention discloses the methods that a kind of capsule file of nested type is updated to BIOS, comprising the following steps:
Step 1: nested integration is carried out to multiple capsule files；
Step 2: when brushing into BIOS, SMI is to capsule document analysis, if discovery capsule file is that format is nested,
Further parse, after all parse, obtained file will be parsed summarize and keep in unified memory region, and uniformly brush into
In BIOS ROM.
Multiple capsule files are integrated, Integration Mode uses same type or different types of Safe Format.
Multiple capsule file nesting numbers of plies can be one or more layers.
After capsule document analysis, overlapping, the insertion in region can be done.
The utility model has the advantages that compared with prior art, the present invention the present invention passes through the capsule file format of nested type and writes with a brush dipped in Chinese ink
Method, substantially increase file cracks difficulty, increases the elasticity of ROM modifier area, reduces ROM and writes with a brush dipped in Chinese ink repeat region
The number corresponding time for reducing ROM and writing with a brush dipped in Chinese ink is written.
Detailed description of the invention
Fig. 1 is flow chart of the invention；
Fig. 2 is capsule integrating documents schematic diagram of the invention；
Fig. 3 is the mapping relations figure of the present invention with reason list capsule file；
After Fig. 4 is capsule document analysis, overlapping, the insertion schematic diagram in region are done.
Specific embodiment
The present invention is further explained with reference to the accompanying drawings and examples.
Use the BIOS capsule file of certain Safe Format, it is preferred that can be based on Microsoft's PE file format
Capsule file format is integrated multiple capsule files, Integration Mode with reaching the universal of file format
The Safe Format of same type can be used.It is reproduction one big in short, be exactly the polymerization of multiple small capsule files
The Safe Format of capsule file, these capsule files can be identical, can not also be identical, and the nested number of plies can be one layer
Or limited multilayer, it is specific as shown in Figure 2.
When brushing into BIOS, SMI first parses big capsule file, is the discovery that format nesting, then parse each small
Capsule after all having parsed, then unifies to brush in BIOS ROM, mapping relations such as Fig. 3 with reason list capsule file
It is shown.
Former capsule file can only multiple continuums in Mapping B IOS ROM, and present capsule 1, capsule
2 after parsing, overlapping, the insertion in region can be done, specifically as shown in figure 4, capsule file, parses capsule file 1
~capsule file 6, wherein capsule file 1, capsule file 2 write with a brush dipped in Chinese ink corresponding position, can inside ROM complete phase
Together, capsule file 3, capsule file 4 can overlap, and be easy to understand, down the position of capsule file 4
Point is moved, capsule file 5, capsule file 6 belong to insertion, and capsule file 6 is in the region of capsule file 5
's.In the case where ensuring safe and reliable environment, the convenience of more new data is substantially increased.
Due to being that first each capsule is first unlocked to be merged into memory afterwards, it is possible to check that needs are overlapped and are embedded in
Region, write-once BIOS ROM from memory, and do not have to separate as the write-in of binary block or multiple capsule
Write-in like that, is first written legacy data, then new data is written after wiping.
Capsule file generated: by taking each nesting uses PE file format as an example, specifically includes the following steps:
Step 1: generating the BIOS capsule file of multiple PE formats；
Step 2: the capsule file secondary in step 1 being packaged, the capsule file of a PE format is made into.
If there is the data of overlapping and insertion, then the successive integration order of capsule file is extremely important, by taking Fig. 4 as an example,
Capsule file 1 is first brushed, then brushes capsule file 2, then what is retained is capsule file 2.Capsule file 3 is first brushed,
Capsule file 4 is brushed again, then lap is the data of capsule file 4.First brush capsule file 5 brushes capsule again
File 6 first brushes capsule file 6 and brushes capsule again then capsule file 6 is present between capsule file 5
File 5, then capsule file 5 is just capped.
BIOS unlocks capsule file and writes with a brush dipped in Chinese ink ROM, specifically includes the following steps:
Step 1, the capsule file for reading in a PE format；
Step 2, the BIOS capsule file that BIOS SMI solution is former multiple PE formats；
Step 3 continues to unlock each capsule file, these files are summarized and keep in unified memory region；
Step 4, BIOS check whether each writing area finally mapped has overlapping and insertion, and lap covering is summarized
It completes；
Step 5: once brushing into corresponding ROM block.
Overlapping, nesting, are completed when capsule file unzips to memory, and do not brush really into BIOS core
Piece.When capsule file 1~6 all unzips to inside memory, after the covering and insertion work that complete simulation in memory,
It just disposably brushes into BIOS chip.
