Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a BIOS program upgrade method, device, and storage medium. Background Art

[0002] A BIOS (Basic Input / Output System) chip stores the BIOS program that provides the lowest-level and most direct hardware control for electronic devices. It is primarily used to initialize and test various hardware devices during the startup process. Typical BIOS chips include, but are not limited to, ROM (Read-Only Memory), PROM (Programmable ROM), and EEPROM (Electrically Erasable Programmable Read Only Memory).

[0003] In actual applications, during the BIOS program development phase, the BIOS chip's storage space can be divided into multiple memory cells. Each memory cell has a different address range, meaning that the memory cells are arranged differently within the BIOS chip. Typically, several designated memory cells within the multiple memory cells are configured to store custom configuration information, while the remaining memory cells within the multiple memory cells are configured to store BIOS program files.

[0004] Over time, the BIOS program files in the BIOS chip need to be upgraded. The current upgrade method involves clearing only the storage cells storing the old BIOS program files, essentially erasing the old BIOS program files from the BIOS chip while retaining the settings in the BIOS chip. Next, the new BIOS program files are written to the BIOS chip to complete the BIOS program upgrade process. However, developing a new BIOS program file may change the layout of the storage cells in the BIOS chip, and this upgrade method can easily result in the BIOS chip's settings not being retained. Therefore, how to successfully retain the existing settings in the BIOS chip during a BIOS program file upgrade is an urgent issue. Summary of the Invention

[0005] Various aspects of the present application provide a BIOS program upgrade method, device, and storage medium for successfully retaining existing setting information in a BIOS chip during a BIOS program file upgrade process.

[0006] An embodiment of the present application provides a BIOS program upgrade method, comprising: in response to a BIOS program upgrade instruction, obtaining first structure information from a new version BIOS program file, the first structure information including at least first address information and a first storage capacity of a target storage unit on a BIOS chip, the target storage unit being a storage unit in the BIOS chip configured to store setting information; obtaining second structure information from an old version BIOS program file, the second structure information including at least second address information and a second storage capacity of the target storage unit on the BIOS chip; if the first storage capacity is greater than or equal to the second storage capacity, reading setting information from the target storage unit on the BIOS chip according to the second address information; and in the process of performing an upgrade on the BIOS chip according to the new version BIOS program file, rewriting the read setting information into the target storage unit on the BIOS chip according to the first address information.

[0007] An embodiment of the present application also provides an electronic device, including: a memory and a processor; the memory is used to store a computer program; the processor is coupled to the memory, and is used to execute the computer program to perform a BIOS program upgrade method.

[0008] An embodiment of the present application also provides a computer storage medium storing a computer program. When the computer program is executed by a processor, the processor can implement a BIOS program upgrade method.

[0009] In an embodiment of the present application, during the BIOS program development phase, structural information encapsulating various layout information of storage units on the BIOS chip is written into the BIOS program file. Thus, when the BIOS program is upgraded, by analyzing the structural information of the target storage units configured to store setting information in the new version BIOS program file and the old version BIOS program file, it is possible to accurately and quickly determine whether the storage capacity of the target storage units has changed before and after the BIOS program file version upgrade. Upon determining that the target storage units have sufficient storage space after the BIOS program upgrade to store the setting information already stored in the BIOS chip before the BIOS program upgrade, the setting information is first read from the BIOS chip, and then the read setting information and the new version BIOS program file are written into the BIOS chip together, thereby ensuring that the complete setting information is retained in the BIOS chip after the program upgrade, thereby ensuring the normal operation of the electronic device.

[0017] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] In actual applications, in order to make full use of the BIOS chip, in addition to storing the BIOS program files, the BIOS chip also stores the more critical setting information required by the electronic device. The setting information includes, but is not limited to, third-party firmware files and system configuration information. Taking the setting information as the system configuration information, usually, the setting subroutine is encapsulated in the BIOS program, and the system configuration information is managed by the setting subroutine. The setting subroutine provides a setting interface for the user to configure the system configuration information, and stores the system configuration information configured by the user in the storage unit specified in the BIOS chip. Among them, the system configuration parameters that can be configured by the user include, but are not limited to: basic parameters such as the system clock, display type and the way to handle self-test errors at startup, disk drive setting parameters, memory setting parameters and power management setting parameters, etc. After the system configuration information is stored in the storage unit specified in the BIOS chip in advance, the electronic device reads the system configuration information stored in the BIOS chip when it is turned on to perform system configuration and related hardware control, thereby ensuring the normal operation of the electronic device.

[0019] Over time, the BIOS program files in the BIOS chip need to be upgraded. The current upgrade method involves clearing only the storage cells containing the old BIOS program files, essentially erasing the old BIOS program files from the BIOS chip while retaining the settings in the BIOS chip. Next, the new BIOS program files are written to the BIOS chip to complete the BIOS program upgrade process. However, the development of a new BIOS program file may change the layout of the storage cells in the BIOS chip, and this upgrade method can easily result in the BIOS chip's settings not being retained.

[0020] In response to the above technical problems, the embodiments of the present application provide a BIOS program upgrade method, device and storage medium. In the embodiments of the present application, during the BIOS program development stage, structural information encapsulating various layout information of storage units on the BIOS chip is written into the BIOS program file. In this way, when the BIOS program is upgraded, the structural information of the target storage unit configured to store setting information in the new version BIOS program file and the old version BIOS program file is analyzed, and it can be accurately and quickly known whether the storage capacity of the target storage unit has changed before and after the BIOS program file version upgrade. When it is determined that the target storage unit has enough storage space to store the setting information that has been saved in the BIOS chip before the BIOS program upgrade after the BIOS program upgrade, the setting information is first read out from the BIOS chip, and then the BIOS writes the read setting information and the new version BIOS program file into the BIOS chip together, thereby ensuring that the complete setting information is still retained in the BIOS chip after the program upgrade, thereby ensuring the normal operation of the electronic device.

[0021] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0022] Figure 1 This is a flow chart of a BIOS program upgrade method provided in an embodiment of the present application. The method can be executed by a BIOS program upgrade device, which can be implemented by software and / or hardware and can generally be integrated into an electronic device. Figure 1 , the method may include the following steps:

[0023] 101. In response to a BIOS program upgrade instruction, obtain first structure information from a new version BIOS program file, where the first structure information includes at least first address information and a first storage capacity of a target storage unit on a BIOS chip. The target storage unit is a storage unit in the BIOS chip configured to store setting information.

[0024] 102. Obtain second structure information from an old version BIOS program file, where the second structure information at least includes second address information and a second storage capacity of a target storage unit on a BIOS chip.

[0025] 103. If the first storage capacity is greater than or equal to the second storage capacity, read the setting information BIOS from the target storage unit on the BIOS chip according to the second address information.

[0026] 104. During the upgrade process of the BIOS chip according to the new version BIOS program file, the read setting information is rewritten into the target storage unit on the BIOS chip according to the first address information.

[0027] In practice, over time, application requirements change, leading to the need for a BIOS upgrade. For example, the need to write more system configuration information to the BIOS chip to control more hardware in an electronic device may necessitate a BIOS upgrade. Another example is the need to expand BIOS functionality, which may necessitate a BIOS upgrade.

[0028] For ease of understanding, the BIOS program files are divided according to the order of BIOS program upgrades. The BIOS program files before the upgrade are called old version BIOS program files, and the BIOS program files after the upgrade are called new version BIOS program files. The new version BIOS program files can be developed based on the old version BIOS program files. Specifically, the source code in the old version BIOS program files is updated based on the program upgrade requirements to obtain new source code, and a new version BIOS program file is generated based on the new source code. In the process of developing a new version of the BIOS program file, the layout information of each storage unit on the BIOS chip may be changed. Among them, the layout information of the storage unit mainly refers to the address range of the storage unit in the BIOS chip. Different storage units have different address ranges in the BIOS chip. The address range specifically refers to the storage address range from the starting address of the storage unit in the BIOS chip to the starting address of the storage unit in the BIOS chip. For ease of understanding, Figure 2 The address ranges of multiple blocks shown in the figure before and after the BIOS program file upgrade are used as an example to illustrate. Figure 2 In the BIOS, the address range of the entire BIOS chip is [0,1000]. The BIOS chip is divided into multiple blocks such as Block1, Block2, Block3, Block4, etc. Figure 2Each block in the BIOS chip represents a storage unit. In the old BIOS program file, the address range of Block 1 is configured to be [0, 100), the address range of Block 2 is configured to be [100, 300), the address range of Block 3 is configured to be [300, 800), and the address range of Block 4 is configured to be [800, 1000]. In the new BIOS program file, the address range of Block 1 is configured to be [0, 100), the address range of Block 2 is configured to be [100, 500), the address range of Block 3 is configured to be [500, 900), and the address range of Block 4 is configured to be [900, 1000]. The address ranges of Block 2, Block 3, and Block 4 have all changed. Continuing with the example of setting the system configuration information as the setting information, if Block 3 and Block 4 are blocks specifically used to store the system configuration information, according to the existing BIOS program upgrade method, part of the system configuration information stored in Block 3 and Block 4 will be cleared during the program upgrade process and cannot be retained. This will cause the system configuration information in the BIOS chip to be incomplete, affecting the normal operation of the electronic device.

[0029] In this embodiment, the layout information of each storage unit on the BIOS chip can be added to the BIOS program file. In this way, before upgrading the BIOS chip, the layout information of each storage unit in the new version BIOS program file and the old version BIOS program file can be compared to accurately identify whether the layout of the storage units in the BIOS chip has changed.

[0030] Further, optionally, to facilitate the management of storage unit layout information, a structure consisting of multiple fields can be defined to encapsulate various storage unit layout information. Optionally, the fields in the structure recording storage unit layout information include, but are not limited to, an identification field, a starting address field, an ending address field, an address range field, a storage capacity field, a type field, and a reserved field. The identification field records the storage unit's identifier (which can be globally unique); the starting address field records the storage unit's starting address in the BIOS chip; the ending address field records the storage unit's ending address in the BIOS chip; the address range field records the address range of the storage unit in the BIOS chip; and the type field identifies the storage unit's type. Storage unit types can be categorized based on the content stored in the storage unit. For example, storage units can be categorized into data storage units for storing various configuration information, such as system configuration information, code storage units, or other types of storage units, depending on the content stored. A data storage unit can refer to a storage unit for storing various configuration information, such as system configuration information. A code storage unit can refer to a storage unit for storing BIOS program code. Other storage units are used to store information other than setup information and BIOS program code. The reserved field is used to record information that is subsequently added to the storage unit.

[0031] For example, the structure recording the layout information of the storage unit can be defined as:

[0032] typedef struct{

[0033] EFI_GUID Guid; / / The EFI_GUID Guid field is an identification field;

[0034] UINT32 Offset; / / UINT32 represents an unsigned integer, and the Offset field refers to the starting address field;

[0035] UINT32 Size; / / Size field refers to the storage capacity field;

[0036] UINT32 Type; / / Type field refers to the type field

[0037] UINT32 Reserved; / / The Reserved field refers to the reserved field;

[0038] }BLOCK_AREA / / BLOCK_AREA represents the structure information reflecting the layout information of the storage unit.

[0039] In this embodiment, the storage unit on the BIOS chip that is configured to store configuration information is referred to as the target storage unit. Storage units on the BIOS chip other than the target storage unit are referred to as other storage units. It is worth noting that, after a target storage unit is configured to store configuration information, it can only be used to store configuration information. Thus, during the development of a new version of the BIOS program file, the function of the target storage unit cannot be changed; that is, the target storage unit cannot be used to store information other than configuration information.

[0040] In this embodiment, the BIOS program upgrade instruction can be manually triggered by the user or automatically triggered. After the BIOS program upgrade instruction is triggered, the structure information of the target storage unit is obtained from the new version BIOS program file and the old version BIOS program file respectively according to the identifier of the target storage unit. For ease of understanding and distinction, the structure information of the target storage unit in the new version BIOS program file is referred to as first structure information. The structure information of the target storage unit in the old version BIOS program file is referred to as second structure information.

[0041] In this embodiment, after obtaining first structure information of a target storage unit from a new version BIOS program file and second structure information of the target storage unit from an old version BIOS program file, the first structure information and the second structure information are analyzed to identify whether the layout information of the target storage unit has changed before and after the BIOS program file version upgrade. In this embodiment, the key is to analyze whether the storage capacity of the target storage unit has changed before and after the BIOS program file version upgrade. Specifically, the size relationship between the first storage capacity in the first structure information and the second storage capacity in the second structure information is analyzed. If the first storage capacity is greater than or equal to the second storage capacity, it indicates that the address range of the target storage unit on the BIOS chip remains unchanged or increases after the BIOS program upgrade relative to before the BIOS program upgrade. In this case, the target storage unit has sufficient storage space to store the settings information stored in the BIOS chip before the BIOS program upgrade. If the first storage capacity is less than the second storage capacity, it indicates that the address range of the target storage unit on the BIOS chip has decreased after the BIOS program upgrade relative to before the BIOS program upgrade. In this case, the target storage unit does not have sufficient storage space to store the settings information stored in the BIOS chip before the BIOS program upgrade. Based on the above, the BIOS program upgrade operation is performed only when it is determined that the first storage capacity is greater than or equal to the second storage capacity, so as to ensure that the setting information can be completely stored in the BIOS chip.

[0042] In this embodiment, when determining to perform a BIOS program upgrade operation on a BIOS chip, the configuration information stored in the target storage unit on the BIOS chip is first read out. Then, during the upgrade process for the BIOS chip according to the new version of the BIOS program file, the read configuration information is rewritten to the target storage unit on the BIOS chip according to the first address information. Furthermore, during the upgrade process, a clear operation is first performed on the BIOS chip, that is, data on the BIOS chip is cleared, and then the read configuration information is rewritten to the target storage unit on the BIOS chip, and the new version of the BIOS program file is written to other storage units on the BIOS chip, thereby completing the BIOS program upgrade.

[0043] It is worth noting that when reading the configuration information stored in the target storage unit on the BIOS chip, the configuration information can be read from the target storage unit on the BIOS chip based on the second address information of the target storage unit. The second address information may include the starting address and / or ending address of the target storage unit on the BIOS chip. It should be understood that when the second address information only includes the starting address or the ending address, the address range of the target storage unit can be determined in combination with the second storage capacity, and the configuration information can be read from the target storage unit on the BIOS chip based on the address range of the target storage unit.

[0044] It is worth noting that when the read setting information is rewritten into the target storage unit on the BIOS chip, the setting information can be rewritten into the target storage unit on the BIOS chip based on the first address information of the target storage unit. The first address information can include the starting address and / or ending address of the target storage unit on the BIOS chip. It should be understood that when the first address information only includes the starting address or the ending address, the address range of the target storage unit can be determined in combination with the first storage capacity, and the setting information can be rewritten into the target storage unit on the BIOS chip based on the address range of the target storage unit.

[0045] Similarly, when writing a new version of the BIOS program file into other storage units on the BIOS chip, the new version of the BIOS program file can be written into the other storage units on the BIOS chip based on the address information of the other storage units.

[0046] Furthermore, to ensure data security of the configuration information, during the BIOS program upgrade process, the configuration information read from the BIOS chip can be backed up before the backed-up configuration information is written to a target storage unit on the BIOS chip. Thus, one implementation method for rewriting the read configuration information to the target storage unit on the BIOS chip based on the first address information is to write the read configuration information to a backup file, and then write the backup file to the target storage unit on the BIOS chip based on the first address information.

[0047] Further optionally, when the first storage capacity is greater than the second storage capacity, when backing up the configuration information read from the BIOS chip, the configuration information may be padded with data, and the padded configuration information may be written to a backup file. Thus, in one optional implementation, when the first storage capacity is greater than the second storage capacity, writing the read configuration information to the backup file specifically includes: calculating the capacity difference between the first and second storage capacities; padded with padding data matching the capacity difference to obtain padded configuration information; and writing the padded configuration information to the backup file. The padded data may be set based on actual needs, such as a binary digit 0 or 1. For example, if the capacity difference between the first and second storage capacities is 1 kB (kilobyte), 1000 bytes of data may be padded after the read configuration information, so that the storage capacity required for the padded configuration data equals the first storage capacity.

[0048] After completing the program upgrade of the BIOS chip, the target storage unit on the BIOS chip currently stores the setting information. In actual applications, because the application requirements have changed, it is necessary to add more setting information to the target storage unit. Therefore, further optionally, after completing the BIOS program upgrade, the newly added setting information can also be written into the target area in the BIOS chip in response to the operation of adding the setting information. The target area is the storage space in the target storage unit corresponding to the fill data. It is worth noting that the target area is a storage space specifically used to write the newly added setting information. When the newly added setting information is written to the target area, the fill data originally written to the target area is cleared. Taking the setting information as system configuration information as an example, the setting subroutine encapsulated by the BIOS program can provide a setting interface to the user. In response to the user's operation of adding system configuration information on the setting interface, the setting subroutine obtains the newly added system configuration information and stores it in the target area in the target storage unit of the BIOS chip to complete the operation of adding the system configuration information in the target storage unit.

[0049] In actual application, the first storage capacity of the target storage unit recorded in the new version BIOS program file may be smaller than the first storage capacity of the target storage unit recorded in the old version BIOS program file. The reason for this situation may be a mistake in program development or the new version BIOS program file has been illegally tampered with, but is not limited to these reasons. In order to ensure the reliability of the BIOS program upgrade, further optional, such as Figure 1 As shown, the above method may further include: step 105, if the first storage capacity is smaller than the second storage capacity, outputting a prompt message, the prompt message being used to prompt the modification of the new version BIOS program file with the goal of increasing the storage capacity of the target storage unit.

[0050] It is worth noting that there is no restriction on the order of executing step 101 and step 102, and they can be executed sequentially or in parallel.

[0051] The BIOS program upgrade method provided by the embodiment of the present application, during the BIOS program development phase, writes structural information encapsulating various layout information of storage units on the BIOS chip into the BIOS program file. In this way, when the BIOS program is upgraded, the structural information of the target storage unit configured to store setting information in the new version BIOS program file and the old version BIOS program file is analyzed, and it can be accurately and quickly determined whether the storage capacity of the target storage unit has changed before and after the BIOS program file version upgrade. When it is determined that the target storage unit has sufficient storage space after the BIOS program upgrade to store the setting information that was already stored in the BIOS chip before the BIOS program upgrade, before clearing the data in the BIOS chip, the setting information is first read from the BIOS chip, and then the BIOS writes the read setting information and the new version BIOS program file into the BIOS chip, thereby ensuring that the BIOS chip after the program upgrade still retains the complete setting information, thereby ensuring the normal operation of the electronic device.

[0052] In some optional embodiments, a global structure can be defined to facilitate global control of the layout information of the entire BIOS chip. For ease of distinction, the layout information of the entire BIOS chip is referred to as global layout information, and the structure that records the global layout information of the entire BIOS chip is referred to as a layout structure. Optionally, the fields of the global layout structure include, but are not limited to, a layout structure identification field, a search flag field, a verification information field, a program version field, a storage unit quantity field, and a storage unit description field. The layout identification field is used to record the layout structure identification corresponding to the BIOS chip's layout information (this identification can be a globally unique identification); the search flag field is used to indicate the search entry for the layout information. The verification information field is used to record relevant information for verifying the BIOS chip's layout information. The program version field is used to record the version information of the BIOS program file. The storage unit quantity field is used to record the number of storage units in the BIOS chip. The storage unit description field is used to record the structure information of at least one storage unit on the BIOS chip.

[0053] For example, the layout structure that records the global layout information of the entire BIOS chip can be defined as:

[0054] typedef struct{

[0055] EFI_GUID Guid; / / EFI_GUID Guid refers to the globally unique layout structure identifier;

[0056] UINT32 Signature; / / The Signature field refers to the search flag field, and the field value of the search flag field is fixed to "_RL_" for example;

[0057] UINT32 CheckSum; / / The CheckSum field is a checksum information field. The field value of the CheckSum field can be a checksum.

[0058] UINT32 Version; / / The Version field refers to the program version field;

[0059] UINT32 NumberOfBlock; / / NumberOfBlock field refers to the number of storage units field;

[0060] BLOCK_AREA Descriptors[0]; / / BLOCK_AREA Descriptors[0] field refers to the storage unit description field

[0061] }ROM_LAYOUT; / / ROM_LAYOUT represents the structure information reflecting the global layout information of the entire BIOS chip.

[0062] For ease of understanding, Figure 3 The layout structure shown is used as an example for explanation. Figure 3 The figure shows that in a BIOS ROM file (also known as a BIOS program file) with a data size of 64M, a ROM_LAYOUT layout structure is added to the BIOS ROM file. According to the globally unique layout structure identifier ( Figure 3 (GUID is the layout structure identifier.) You can find the ROM_LAYOUT layout structure in the BIOS ROM file. This ROM_LAYOUT layout structure records the identifiers and structure information of three storage units. The identifiers of the three storage units are GUID1, GUID2, and GUID3. Figure 3 The four data items in the row containing the search flag "_RL_" are the search flag "_RL_", verification information (0x1276111), program version information (0x00000000), and the number of storage units (0x00000003). The four data items in the row below the row containing storage unit GUID1 are the structure information for storage unit GUID1. These items are, in order, the starting address (0x00000000), storage capacity (0x00010000), type information (0x00000000), and the reserved field value (0x00000000). Similarly, the four data items in the row below the row containing storage unit GUID2 are the structure information for storage unit GUID2; and the four data items in the row below the row containing storage unit GUID3 are the structure information for storage unit GUID3.

[0063] For ease of understanding and distinction, the global layout information recorded by the layout structure in the new version BIOS program file is referred to as first global layout information, and the global layout information recorded by the layout structure in the old version BIOS program file is referred to as second global layout information. Based on the first and second global layout information, it is also possible to accurately and quickly determine whether the storage capacity of the target storage unit has changed before and after the BIOS program file version upgrade, thereby determining whether to perform the BIOS program upgrade operation. Based on this, embodiments of the present application provide another BIOS program upgrade method. Figure 4 This is a flow chart of another BIOS program upgrade method provided by an embodiment of the present application. This method can be executed by a BIOS program upgrade device, which can be implemented by software and / or hardware and can generally be integrated into an electronic device. Figure 4, the method may include the following steps:

[0064] 401. In response to a BIOS program upgrade instruction, obtain first global layout information from a new version of the BIOS program file, where the first global layout information includes at least an identifier of each storage unit on the BIOS chip and its corresponding structure information. Based on an identifier of a target storage unit included in the BIOS upgrade instruction, obtain structure information corresponding to the target storage unit from the first global layout information as first structure information.

[0065] 402. Obtain second global layout information from the old version BIOS program file, where the second global layout information includes at least an identifier of each storage unit on the BIOS chip and its corresponding structure information. Based on the identifier of the target storage unit included in the BIOS upgrade instruction, obtain the structure information corresponding to the target storage unit from the second global layout information as the second structure information.

[0066] 403. If the first storage capacity is greater than or equal to the second storage capacity, read the setting information BIOS from the target storage unit on the BIOS chip according to the second address information.

[0067] 404. During the upgrade process of the BIOS chip according to the new version BIOS program file, the read setting information is rewritten into the target storage unit on the BIOS chip according to the first address information.

[0068] It is worth noting that there is no restriction on the order of executing step 401 and step 402, and they can be executed sequentially or in parallel.

[0069] In this embodiment, the new version BIOS program file can be obtained by modifying the old version BIOS program file. Therefore, in an optional implementation, before responding to the BIOS program upgrade instruction, the process further includes: obtaining the old version BIOS program file, the old version BIOS program file including the old version source code, the old version source code including the second global layout information; modifying at least the second global layout information in the old version source code based on the program upgrade requirements to obtain the new version source code; and generating the new version BIOS program file based on the new version source code.

[0070] In this embodiment, first global layout information can be queried from the new version BIOS program file based on the globally unique layout structure identifier. The first global layout information includes at least the identifier of each storage unit on the BIOS chip and its corresponding structure information. The first structure information of the target storage unit is obtained from the first global layout information based on the identifier of the target storage unit. Similarly, second global layout information can be queried from the old version BIOS program file based on the globally unique layout structure identifier. The second global layout information includes at least the identifier of each storage unit on the BIOS chip and its corresponding structure information. The second structure information of the target storage unit is obtained from the second global layout information based on the identifier of the target storage unit.

[0071] In this embodiment, after obtaining the first structure information of the target storage unit from the new version BIOS program file and the second structure information of the target storage unit from the old version BIOS program file, the target storage unit is analyzed to determine whether the storage capacity has changed before and after the BIOS program file version upgrade. If it is determined that the first storage capacity is greater than or equal to the second storage capacity, steps 403 and 404 are executed. The specific implementation of steps 403 and 404 can be found in steps 103 and 104 of the aforementioned embodiment, respectively, and will not be repeated here.

[0072] In specific applications, after obtaining the first global layout information from the new version of the BIOS program file, the first structure information of the target storage unit can be directly obtained from the first global layout information. Further optionally, in order to perform the BIOS program upgrade more safely, before obtaining the first structure information of the target storage unit from the first global layout information, the data security of the first global layout information can also be verified. Therefore, in an optional implementation method, before obtaining the structure information corresponding to the target storage unit as the first structure information from the first global layout information according to the identifier of the target storage unit contained in the BIOS upgrade instruction, it is also possible to: generate second verification information based on the basic information in the first global layout information and / or the structure information corresponding to the selected storage unit; if the first verification information and the second verification information are the same, execute the step of obtaining the structure information corresponding to the target storage unit as the first structure information from the first global layout information according to the identifier of the target storage unit contained in the BIOS upgrade instruction.

[0073] Specifically, the first global layout information also includes first verification information and basic information, and the basic information includes at least one of the program version information of the new version BIOS program file and the number of storage units on the BIOS chip. It is worth noting that the first verification information is generated during the program development phase of the new version BIOS program file based on the basic information of the first global layout information and / or the structural information corresponding to the selected storage unit, and is written into the new version BIOS program file. The second verification information is generated during the program upgrade phase of the new version BIOS program file based on the basic information of the first global layout information and / or the structural information corresponding to the selected storage unit in order to ensure the security of the BIOS program upgrade. It should be understood that the information involved in calculating the first verification information can be selected according to the actual situation and is not limited to the program version information of the new version BIOS program file, the number of storage units on the BIOS chip, and the structural information corresponding to the selected storage unit. Of course, the information involved in calculating the first verification information should also be applied to calculating the second verification information.

[0074] In this embodiment, the generation method of the first verification information and the second verification information is not limited. For example, the first verification information and the second verification information may be checksum information obtained by processing the basic information and / or the structural information corresponding to the selected storage unit using a checksum algorithm. For another example, the first verification information and the second verification information may be verification information obtained by processing the basic information and / or the structural information corresponding to the selected storage unit using a longitudinal redundancy check (LRC) algorithm. For another example, the first verification information and the second verification information may be verification information obtained by processing the basic information and / or the structural information corresponding to the selected storage unit using a cyclic redundancy check (CRC) algorithm.

[0075] In this embodiment, after obtaining the first verification information from the first global layout information and generating the second verification information based on the basic information in the first global layout information and / or the structural information corresponding to the selected storage unit, the data security of the first global layout information is verified based on the comparison result of the first verification information and the second verification information. If the first verification information and the second verification information are the same, it means that the first global layout information in the new version BIOS program file to be upgraded to the BIOS chip has not been illegally tampered with and the data security is good. At this time, the step of obtaining the structural information corresponding to the target storage unit from the first global layout information as the first structural information according to the identifier of the target storage unit contained in the BIOS upgrade instruction can be executed. If the first verification information and the second verification information are the same, it means that the first global layout information in the new version BIOS program file to be upgraded to the BIOS chip is likely to have been illegally tampered with and the data security is poor. There is a security risk in continuing the BIOS program upgrade. At this time, a risk warning message can be output to remind the person responsible for the BIOS program upgrade that there is a security risk in the current BIOS program upgrade. The person responsible for the BIOS program upgrade can decide whether to continue the BIOS program upgrade based on the risk warning information.

[0076] Further optionally, to improve the accuracy and efficiency of the BIOS program upgrade, the configuration information read from the BIOS chip and the new version BIOS program file can be merged, and the merged file can be written as a whole to the BIOS chip to complete the BIOS program upgrade. As an optional implementation, the implementation process of step 404 is as follows: based on the structural information corresponding to each storage unit included in the first global layout information, the relative position relationship between the target storage unit and other storage units is determined; based on the relative position relationship, the configuration information read and the new version BIOS program file are merged to obtain a target file; a clear operation is performed on the BIOS chip, and the target file is directly written to the cleared BIOS chip to complete the BIOS program upgrade.

[0077] Optionally, when determining the relative positional relationship between the target storage unit and other storage units based on the structural information corresponding to each storage unit included in the first global layout information, the structural information corresponding to the other storage units can be obtained from the first global layout information, and the structural information corresponding to the other storage units at least includes the address information of the other storage units on the BIOS chip; based on the first address information and the address information of the other storage units on the BIOS chip, the relative positional relationship between the target storage unit and the other storage units is determined.

[0078] Specifically, the relative position relationship of each storage unit on the BIOS chip can be determined based on the address information of each storage unit on the BIOS chip, and the relative position relationship can reflect the order in which data is written to the storage unit on the BIOS chip. Figure 2 For example, the BIOS chip includes multiple blocks such as Block 1, Block 2, Block 3, and Block 4 in sequence. Data is written to Block 1, Block 2, Block 3, Block 4, and so on in sequence according to the data writing order. Therefore, when merging the read setting information and the new version BIOS program file, first, the storage units corresponding to the multiple sub-files in the new version BIOS program file are determined based on the new version BIOS program file, as well as the storage units corresponding to the read setting information. Then, based on the relative positional relationship between the multiple storage units, the data writing order of the multiple sub-files and the read setting information is determined, and the multiple sub-files in the new version BIOS program file and the read setting information are merged in sequence according to the data writing order. Finally, the merged target file is directly written to the cleared BIOS chip. At this point, the data stored in each storage unit of the BIOS chip is consistent with the data stored in each storage unit required by the new version BIOS program file.

[0079] Further optional, such as Figure 4 As shown, the above method may further include: Step 405: if the first storage capacity is smaller than the second storage capacity, outputting a prompt message, the prompt message being used to prompt the user to modify the new version of the BIOS program file with the goal of increasing the storage capacity of the target storage unit. The specific implementation of Step 405 can be found in Step 105 of the above embodiment, and will not be repeated here.

[0080] The BIOS program upgrade method provided by the embodiment of the present application writes the global layout information of the entire BIOS chip into the BIOS program file during the BIOS program development phase. In this way, when the BIOS program is upgraded, the structural information corresponding to the target storage unit configured to store setting information can be extracted from the global layout information of the new version BIOS program file and the global layout information of the old version BIOS program file. By analyzing the structural information of the target storage unit in the new version BIOS program file and the old version BIOS program file, it is possible to accurately and quickly determine whether the storage capacity of the target storage unit has changed before and after the BIOS program file version upgrade. When it is determined that the target storage unit has sufficient storage space after the BIOS program upgrade to store the setting information that has been saved in the BIOS chip before the BIOS program upgrade, before clearing the data in the BIOS chip, the setting information is first read from the BIOS chip, and the read setting information and the new version BIOS program file are written into the BIOS chip together. In this way, it can be ensured that the BIOS chip after the BIOS program upgrade still retains complete setting information, thereby ensuring the normal operation of the electronic device.

[0081] It should be noted that the execution entity of each step of the method provided in the above embodiment can be the same device, or the method can be executed by different devices. For example, the execution entity of steps 101 to 105 can be device A; for another example, the execution entity of steps 101 and 102 can be device A, and the execution entity of steps 103 to 105 can be device B; and so on.

[0082] In addition, some of the processes described in the above embodiments and the accompanying drawings include multiple operations that appear in a specific order, but it should be clearly understood that these operations may not be executed in the order in which they appear in this article or may be executed in parallel. The serial numbers of the operations, such as 101, 102, etc., are only used to distinguish between different operations, and the serial numbers themselves do not represent any order of execution.

It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., and do not represent a sequential order, nor do they limit "first" and "second" to different types.
