The Basic Input / Output System (BIOS) provides the lowest-level, most direct hardware configuration and control for servers, as well as system parameters for the BMC, BIOS, and the operating system booted within the BIOS. System parameters are stored in the BIOS's Setup module and can be modified by the user as needed.

[0005] Existing technology typically uses the Redfish standard to connect a baseboard management controller (BMC) to a basic input / output system (BIOS) via a USB (Universal Serial Bus) network card to transmit setup options.

[0165] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0166] To facilitate understanding of the technical solutions and technical effects of the embodiments of the present application, the prior art of the present application will be briefly described below.

[0167] The baseboard management controller is a controller used to monitor and manage the server, and the basic input and output system is used to provide the lowest-level and most direct hardware settings and control for the server, as well as provide some system parameters for the baseboard management controller, the basic input and output system, and the operating system booted in the basic input and output system. Among them, the system parameters are stored in the setting module of the basic input and output system, and the user can modify the system parameters according to actual needs. The existing technology generally uses Redfish to connect the baseboard management controller and the basic input and output system through a USB network card to transmit setting options. The data volume of the setting options is large, at more than 100KB (Kilobyte). Redfish is a management standard based on HTTPs (Hypertext Transfer Protocol Secure, a secure version of the HTTP protocol) service. Using Redfish to transmit setting options requires adding a USB network card hardware module, and the speed of transmitting setting options is slow.

The method is applied to a server, and the server includes a baseboard management controller, a basic input / output system (BIOS), and a shared memory space between the baseboard management controller and the BIOS. The BIOS also provides a setting interface. The BIOS and the baseboard management controller are connected via a PCIe path, and the setting interface is used to display setting options. Specifically, the method may include the following steps:

[0169] Step 101: When a basic input / output system sends a first setting option to a baseboard management controller, the basic input / output system collects the first setting option before displaying a setting interface and / or after modifying the setting option through the setting interface, and stores the first setting option in a shared memory space.

[0170] In an embodiment of the present application, a server includes a baseboard management controller, a basic input / output system (BIOS), and a shared memory space. The BIOS also provides a settings interface that displays setting options. A user can view the setting options through the settings interface and modify the setting options as needed to modify the system parameters corresponding to the setting options. The setting options include a setting option name and a corresponding setting option value. Different setting options have different formatting requirements, such as the setting option name and yes / no, the setting option name and a number from 1 to 10, etc.

[0171] The baseboard management controller (BMC) and the basic input / output system (BIOS) are connected via a PCIe (PCIe) link. The BIOS runs in a server host, while the BMC is a terminal device in the PCIe link, operating independently of the server host. PCIe is a high-speed serial computer expansion bus standard. The BMC sends a command to the BIOS to request address space. The BIOS requests a first address space from the server host via a base address register in the PCIe configuration space within the BIOS. The BMC also has a second address space corresponding to the first address space. Together, the first and second address spaces constitute a shared memory space between the BMC and the BIOS.

[0172] The BIOS settings module stores a large number of BMC system parameters. Users can modify settings to adjust system parameters as needed. When the BIOS needs to send settings to the BMC, before the BIOS enters the settings interface and / or after the user modifies settings to modify system parameters as needed, the BIOS collects all settings as a first set of settings and stores them in the shared memory space.

[0173] Step 102: The PCIe channel sends the first setting option to the baseboard management controller;

[0174] In the embodiment of the present application, the PCIe bus hardware sends the first configuration option stored in the shared memory space to the baseboard management controller.

[0175] Step 103 : The baseboard management controller adjusts the baseboard management controller based on the first setting option.

[0176] After receiving the first setting option, the baseboard management controller analyzes the first setting option, finds the first setting option related to the baseboard management controller, and adjusts the baseboard management controller based on the system parameters corresponding to the first setting option related to the baseboard management controller. The baseboard management controller also saves the received first setting option in a file named current_setting.json.

[0177] In an embodiment of the present application, a server includes a baseboard management controller (BMC), a basic input / output system (BIOS), and a shared memory space between the BMC and the BIOS; the BIOS and the BMC are connected via a PCIe path; the BIOS also provides a setting interface for displaying setting options; when the BIOS sends a first setting option to the BMC, before the server displays the setting interface and / or after the setting option is modified via the setting interface, the BIOS collects the first setting option and stores the first setting option in the shared memory space; the PCIe path sends the first setting option to the BMC; and the BMC adjusts the BMC based on the first setting option. The present application transmits setting options via the PCIe path, does not require additional hardware modules, increases the transmission speed of the setting options, and makes the transmission process of the setting options more secure and reliable.

[0178] Furthermore, in some embodiments of the present application described above, the shared memory space includes a first area; and step 101 further includes:

[0179] In sub-step S21 , the basic input / output system converts the collected first setting option into a first character string.

[0180] In sub-step S22, the basic input and output system calculates the length of the first character string based on the first character string, and determines whether the length of the first character string exceeds a preset length range;

[0181] Sub-step S23 , if the length of the first character string does not exceed a preset length range, the BIOS uses the first character string as the second character string;

[0182] In sub-step S24 , the BIOS stores the second character string in the first area.

[0183] In the embodiment of the present application, the shared memory area includes a first area, also called a current setting area, which is used to store setting options sent by the basic input and output system to the baseboard management controller.

[0184] The basic input and output system converts the collected first setting option into a first string in Json format and calculates the length of the first string. Based on the length of the first string, the basic input and output system determines whether the first string exceeds a preset length range, that is, the length range of the first area in the shared memory space. If the first string is within the preset length range, the basic input and output system uses the first string as the second string. The basic input and output system stores the second string in the first area. The embodiment of the present application stores the first string within the preset length range in the first area, ensuring that the first string can be successfully stored in the first area and smoothly sent to the baseboard management controller.

[0185] Furthermore, in some embodiments of the present application described above, the first area further stores a first data field corresponding to the first character string; and the method further includes:

[0186] The basic input and output system calculates a first check value of the first character string based on the first character string;

[0187] The basic input and output system stores the length of the first character string and the first check value in the first data field.

[0188] In an embodiment of the present application, the first area also stores a first data field corresponding to the first string, i.e., a data header of the first area. The basic input / output system converts the collected first setting option into a first string in JSON format and calculates a first checksum value for the first string. The basic input / output system also stores the length of the first string and the first checksum value in the first data field, so that the baseboard management controller can determine whether the first string corresponding to the first setting option is correct when receiving the first setting option.

[0189] Furthermore, in some embodiments of the present application described above, the method further includes:

[0190] If the length of the first character string exceeds a preset length range, the basic input and output system compresses the first character string to obtain a compressed character string;

[0191] The basic input and output system stores information about whether the first character string is compressed in a first data field;

[0192] The basic input and output system calculates the length of the compressed string and determines whether the length of the compressed string exceeds a preset length range;

[0193] If the length of the compressed character string is within a preset length range, the basic input and output system uses the compressed character string as the second character string.

[0194] In an embodiment of the present application, the basic input / output system determines whether the first string exceeds a preset length range based on the length of the first string, that is, the length range of the first area in the shared memory space. If the length of the first string exceeds the preset length range, the first string is compressed to obtain a compressed string. The basic input / output system again determines whether the length of the compressed string exceeds the preset length range. If the length of the compressed string still exceeds the preset length range, the basic input / output system exits the process of sending the first setting option to the baseboard management controller and sends an error message to the basic input / output system. If the length of the compressed string is within the preset length range, the basic input / output system uses the compressed string as the second string. The basic input / output system stores the second string in the first area. The embodiment of the present application stores the compressed string within the preset length range in the first area, ensuring that the compressed string can be smoothly stored in the first area and smoothly sent to the baseboard management controller.

[0195] Furthermore, in some embodiments of the present application described above, the first data field further includes a first owner field; the first owner field is used to indicate the owner of the first area; and the step of storing the second character string in the first area further includes:

[0196] The BIOS reads the first owner field to get the owner of the first region:

[0197] If the owner of the first area is the basic input and output system, the basic input and output system stores the second character string in the first area.

[0198] In this embodiment of the present application, the first data field also includes a first owner field, which indicates the owner of the first area. Before the BIOS stores the second string in the first area, the BIOS reads the first owner field to obtain the owner of the first area. If the owner of the first area is the BIOS or the first area is unused, the BIOS stores the second string in the first area, ensuring a smooth storage process.

[0199] Furthermore, in some embodiments of the present application described above, the method further includes:

[0200] If the owner of the first area is the baseboard management controller, the basic input and output system suspends storing the second character string in the first area;

[0201] The basic input and output system reads the first owner field again to obtain the owner of the first area.

[0202] In an embodiment of the present application, the first data field also includes a first owner field, and the first owner field indicates the owner of the first area. Before the basic input and output system stores the second character string in the first area, the basic input and output system reads the first owner field to obtain the owner of the first area. If the owner of the first area is the baseboard management controller, the basic input and output system pauses storing the second character string in the first area, sleeps for two seconds, reads the first owner field again, and determines the owner of the first area until the owner of the first area is the basic input and output system or the first area is not in use, and the basic input and output system stores the second character string in the first area. If the owner of the first area is the baseboard management controller after 3 retries, the basic input and output system exits the process of sending the first setting option to the baseboard management controller and sends an error message to the basic input and output system.

[0203] Furthermore, in some embodiments of the present application described above, the first data field further includes a first validity field; the first validity field is used to indicate whether the second character string in the first area is valid; and after storing the second character string in the first area, the following steps are further included:

[0204] The basic input and output system indicates that the second character string in the first area is valid by modifying the first validity field.

[0205] In an embodiment of the present application, the first data field also includes a first validity field, which can indicate whether the second string is valid. After the BIOS stores the second string in the first area, the BIOS modifies the first validity field to 1, indicating that the second string is valid. This facilitates the baseboard management controller to determine whether the second string corresponding to the first setting option is valid when receiving the first setting option.

[0206] The BIOS will also modify the first owner field to release the BIOS from use.

[0207] Furthermore, in some embodiments of the present application described above, before step 103, the following steps are further included:

[0208] The baseboard management controller reads the first validity field to determine whether the second character string is valid;

[0209] If the second character string is valid, the baseboard management controller reads the first owner field to determine the owner of the first area;

[0210] If the owner of the first area is a baseboard management controller, the baseboard management controller extracts a second character string;

[0211] The baseboard management controller parses the second character string to obtain a first setting option.

[0212] In an embodiment of the present application, when the baseboard management controller receives the first setting option, it first reads the first validity field. If the first validity field is 0, indicating that the second string is invalid, the baseboard management controller exits the process of receiving the first setting option. If the first validity field is 1, indicating that the second string is valid, the baseboard management controller reads the first owner field to obtain the owner of the first area. If the owner of the first area is the baseboard management controller or the first area is not used, the first owner field is modified to indicate that the owner of the first area is the baseboard management controller, and the second string is extracted. After extracting the second string, the baseboard management controller modifies the first validity field to 0 and modifies the first owner field to release the use of the baseboard management controller. The baseboard management controller parses the second string to obtain the first setting option corresponding to the second string.

[0213] Furthermore, in some embodiments of the present application described above, extracting the second character string further includes:

[0214] The baseboard management controller reads the first data field to obtain the length of the first character string and information on whether the first character string is compressed;

[0215] The baseboard management controller determines whether the first character string exceeds a preset length range based on the length of the first character string;

[0216] If the length of the first character string exceeds a preset length range, the baseboard management controller determines whether the first character string is compressed based on the information of whether the first character string is compressed;

[0217] If the first character string is not compressed, the baseboard management controller ignores the second character string;

[0218] If the first character string is compressed, the baseboard management controller extracts the second character string.

[0219] In an embodiment of the present application, when the baseboard management controller receives the first setting option, the baseboard management controller reads the first data field to obtain the length of the first character string and information on whether the first character string is compressed. If the length of the first character string exceeds the preset length range and the first character string is not compressed, there is a problem with the second character string, and the baseboard management controller no longer extracts the second character string. If the length of the first character string exceeds the preset length range and the first character string is compressed, the baseboard management controller extracts the second character string and decompresses the second character string. If the first character string does not exceed the preset length range, the second character string is directly extracted, ensuring that the second character string extracted by the baseboard management controller is correct, and the baseboard management controller adjusts the baseboard management controller smoothly based on the first setting option.

[0220] Furthermore, in some embodiments of the present application described above, the step of parsing the second character string to obtain the first setting option further includes:

[0221] The baseboard management controller reads the first data field to obtain a first check value of the first character string;

[0222] The baseboard management controller calculates a second check value of the first character string based on the first character string;

[0223] The baseboard management controller compares the first check value and the second check value to determine whether the first check value and the second check value are the same;

[0224] If the first check value and the second check value are different, the baseboard management controller ignores the second character string;

[0225] If the first check value and the second check value are the same, the baseboard management controller parses the second character string to obtain the first setting option.

[0226] In an embodiment of the present application, when the baseboard management controller receives the first setting option, the baseboard management controller reads the first data field, obtains the first check value of the first string, and calculates the second check value of the first string. The baseboard management controller determines whether the first check value and the second check value are the same; if the first check value and the second check value are not the same, there is a problem with the second string, and the baseboard management controller ignores the second string; if the first check value and the second check value are the same, the baseboard management controller parses the second string to obtain the first setting option. The baseboard management controller finds the first setting option related to the baseboard management controller and calls the relevant functional module in the baseboard management controller to adjust the baseboard management controller according to the system parameters corresponding to the first setting option related to the baseboard management controller. The baseboard management controller also saves the second string in current_setting.json.

[0227] Furthermore, in some embodiments of the present application described above, the method further includes:

[0228] If the owner of the first area is the basic input and output system, the baseboard management controller suspends extracting the second character string;

[0229] The baseboard management controller reads the first owner field again to obtain the owner of the first area.

[0230] In this embodiment of the present application, if the owner of the first area is the BIOS, the baseboard management controller pauses extracting the second string, sleeps for two seconds, and then reads the first owner field again to determine the owner of the first area. The baseboard management controller extracts the second string until the owner of the first area is the baseboard management controller or the first area is unused. If the owner of the first area is the BIOS after three retries, the baseboard management controller exits the process of extracting the second string.

[0231] 2 shows a method for processing a basic input / output system provided in an embodiment of the present application, which is applied to a server. The server includes a baseboard management controller (BMC), a basic input / output system (BIO), and a shared memory space between the BMC and the BIO. The BMC and the BMC are connected via a PCIe path. The BMC stores a preset second character string. The method may specifically include the following steps:

[0232] Step 201: When the baseboard management controller sends a second setting option to the basic input and output system, the baseboard management controller modifies the second character string to obtain a third character string corresponding to the second setting option.

[0233] In an embodiment of the present application, the server includes a baseboard management controller and a basic input / output system. The disk of the baseboard management controller stores a second string corresponding to the first setting option sent by the basic input / output system, and the second string is stored in the current_setting.json file. The baseboard management controller can modify the first setting option received from the basic input / output system, and use the modified first setting option as the second setting option, and send the second setting option to the basic input / output system. When the baseboard management controller sends the second setting option to the basic input / output system, the baseboard management controller modifies the user-specified content in the current_setting.json file, that is, the user-specified modified content in the second string, and obtains the future_setting.json file. The future_setting.json file stores a third string corresponding to the second setting option.

[0234] Step 202: The baseboard management controller stores the third character string in the shared memory space;

[0235] In the embodiment of the present application, the server further includes a shared memory space, and the baseboard management controller can store the third character string in the shared memory space.

[0236] Step 203: The PCIe channel sends the third character string to the basic input and output system;

[0237] In the embodiment of the present application, the PCIe bus hardware may send the third character string stored in the shared memory space to the basic input and output system.

[0238] Step 204: The basic input / output system parses the third character string to obtain a second setting option;

[0239] In an embodiment of the present application, the basic input / output system can receive the third character string and parse the third character string to obtain a data linked list consisting of multiple nodes, each node consisting of a parameter name and a parameter value corresponding to the second setting option.

[0240] In step 205 , the BIOS adjusts the BIOS based on the second setting option.

[0241] The baseboard management controller may adjust the baseboard management controller based on the system parameter corresponding to the second setting option.

[0242] Furthermore, in some embodiments of the present application described above, the shared memory area further includes a second area; the second area is used to store a third string; the second area further stores a second data field corresponding to the third string; the second data field includes a second owner field and a second validity field; the second owner field is used to indicate the owner of the second area, and the second validity field is used to indicate whether the third string in the second area is valid; step 202 further includes:

[0243] Sub-step S31, the baseboard management controller reads the second owner field to obtain the owner of the second area;

[0244] Sub-step S32 , if the owner of the second area is the baseboard management controller, the baseboard management controller stores the third character string in the second area;

[0245] In sub-step S33 , the baseboard management controller modifies the second validity field to indicate that the third character string is valid.

[0246] In an embodiment of the present application, the shared memory area includes a second area, also known as a modification setting area, for storing setting options sent by the baseboard management controller to the basic input / output system, namely, a third string. The second area also stores a second data field corresponding to the third string; the second data field includes a second owner field and a second validity field; the second owner field indicates the owner of the second area, and the second validity field indicates whether the third string is valid.

[0247] When the baseboard management controller sends the third character string to the basic input / output system, the baseboard management controller checks whether the third character string meets a preset format requirement. The setting option includes the name of the setting option and the value corresponding to the setting option. Different setting options have different format requirements, such as the name of the setting option and yes / no, the name of the setting option and a number between 1 and 10, etc.

[0248] The baseboard management controller also includes a screen. If the third character string does not meet format requirements, an error message is displayed on the baseboard management controller screen and the process of sending the third character string to the basic input and output system is terminated. If the third character string does not meet format requirements, the baseboard management controller calculates the length of the third character string and a third check value.

[0249] When the baseboard management controller sends the third string to the basic input / output system (BIOS), the baseboard management controller needs to store the third string in the second area. Before storing the third string in the second area, the baseboard management controller reads the second owner field to obtain the owner of the second area. If the owner of the second area is the baseboard management controller or the second area is unused, the baseboard management controller modifies the second owner field to indicate that the owner of the second area is the baseboard management controller, and stores the third string in the second area. After storing the third string in the second area, the baseboard management controller modifies the second validity field to 1 and modifies the second owner field to release the baseboard management controller from use.

[0250] If the BIOS is the owner of the second area, the BIOS pauses storing the third string in the second area, sleeps for two seconds, and then reads the second owner field again to determine the owner of the second area. The BMC stores the third string in the second area until the BMC becomes the owner of the second area or the second area is unused. If the BIOS is the owner of the second area after three retries, the BMC exits the process of sending the second setting option to the BIOS.

[0251] Furthermore, in some embodiments of the present application described above, before step 204, the method further includes:

[0252] The basic input and output system reads the second validity field to determine whether the third character string is valid;

[0253] If the third character string is valid, the basic input and output system extracts the third character string;

[0254] In an embodiment of the present application, the BIOS cyclically checks the second validity field in the modified setting area, i.e., the second area. When the second validity field becomes 1, the BIOS reads the second owner field to obtain the owner of the second area. If the owner of the second area is the BIOS or the second area is unused, the second owner field is modified to indicate that the owner of the second area is the BIOS, and a third string is extracted. After extracting the third string, the BIOS modifies the second validity field to 0 and modifies the second owner field to release the BIOS from use. The BIOS parses the third string to obtain a data linked list consisting of multiple nodes, each of which consists of a parameter name and parameter value corresponding to the second setting option.

[0255] Furthermore, in some embodiments of the present application described above, the shared memory area further includes a third area; and step 205 further includes:

[0256] Sub-step S31, the basic input and output system determines whether the second setting option meets the preset format requirement;

[0257] Sub-step S32, if the second setting option meets the preset format requirement, the BIOS adjusts the BIOS based on the second setting option;

[0258] In sub-step S33, if the second setting option does not meet the preset format requirement, the basic input and output system converts the second setting option into a fourth character string and stores the fourth character string in the third area; wherein the fourth character string is used to determine whether the second setting option meets the preset format requirement.

[0259] In an embodiment of the present application, the basic input / output system parses the third string to obtain a data linked list consisting of multiple nodes, each node consisting of a parameter name and a parameter value corresponding to the second setting option. The basic input / output system verifies the parameter name and parameter value of each node, and if they meet the format requirements of the setting options, they are placed in a designated location of the non-volatile storage medium. The next time the basic input / output system is started, the basic input / output system can read the parameter name and parameter value corresponding to the second setting option that meets the requirements from the non-volatile storage medium to guide the operation of the basic input / output system. If the format requirements of the setting options are not met, the parameter name and parameter value corresponding to the second setting option that does not meet the requirements and the reason for the non-compliance are converted into a fourth string, and the fourth string is placed in an error list.

[0260] In an embodiment of the present application, the shared memory space also includes a third area. When the basic input / output system sends the fourth character string to the baseboard management controller, the basic input / output system needs to store the fourth character string in the third area, that is, the setting result area. Before the basic input / output system stores the fourth character string in the third area, the basic input / output system reads the owner field of the third area to obtain the owner of the third area. If the owner of the third area is the basic input / output system or the third area is not used, the owner field of the third area is modified to indicate that the owner of the third area is the basic input / output system, and the fourth character string is stored in the third area. After the basic input / output system stores the fourth character string in the third area, the validity field of the third area is modified to 1, and the owner field of the third area is modified to release the basic input / output system from use.

[0261] Furthermore, in some embodiments of the present application described above, the method further includes:

[0262] If the second setting option meets the format requirement of the setting option, the server is restarted to adapt the server to the second setting option.

[0263] In an embodiment of the present application, if the second setting option meets the format requirements of the setting option, since the system parameters corresponding to the second setting option may be different from the running system parameters, the server needs to be restarted to adapt the system parameters corresponding to the second setting option.

[0264] 3 , a processing method for a baseboard management controller provided in an embodiment of the present application is shown, which is applied to a server. The server includes a baseboard management controller, a basic input / output system (BIOS), and a shared memory space between the baseboard management controller and the BIOS. The BIOS and the baseboard management controller are connected via a PCIe path. The shared memory space stores a preset fourth character string. The specific steps are as follows:

[0265] Step 301 , when the basic input / output system sends a fourth character string to the baseboard management controller, the PCIe channel sends the fourth character string to the baseboard management controller;

[0266] Step 302 : The baseboard management controller extracts a fourth character string and determines, based on the fourth character string, whether a second setting option corresponding to the fourth character string meets a preset format requirement.

[0267] In an embodiment of the present application, a server includes a baseboard management controller (BMC), a basic input / output system (BIOS), and a shared memory space. The BMC and BIOS are connected via a PCIe (PCIe) link. The shared memory space includes a third area, which also stores a fourth string. The PCIe link can transmit the fourth string to the BMC. The BMC loops through the validity field in the third area. When the validity field changes to 1, the BMC reads the owner field in the third area to determine the owner of the third area. If the owner of the third area is the BMC or the third area is unused, the BMC modifies the owner field in the third area to indicate that the owner is the BMC and extracts the fourth string. After extracting the fourth string, the BMC modifies the validity field in the third area to 0 and modifies the owner field in the third area to remove the BMC from use. The BMC parses the fourth string. If the fourth string indicates a problem with a second setting option, the BMC displays the name of the parameter with the setting error and the cause of the error on the BMC screen. If the second setting option is correct, the BMC displays a successful setting to the user and saves the fourth string to a file named setting_result.json.

[0336] As for the device embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0337] As an example provided by this application, FIG7 shows a schematic diagram of a setting interface provided by an embodiment of this application. The setting interface is used to display setting options, and the setting options are used to save system parameters. The setting options include the name of the setting option and the corresponding value of the setting option. Different setting options have different format requirements, such as the name of the setting option and yes / no, the name of the setting option and any number from 1 to 10, etc. In Figure 7, Boot Mode is a setting option, Legacy Support is the corresponding value of Boot Mode; Boot Priority is a setting option, UEFI First is the corresponding value of Boot Priority; USB Boot is a setting option, Enabled is the corresponding value of USB Boot; UEFI Boot priority order is a setting option, Windows Boot Manager is the corresponding value of UEFI Boot priority order; Legacy Boot priority order is a setting option, HGST HTS545032A7E380 Realtek PXE BO3 D00 is the corresponding value of UEFI Boot priority order.

[0338] As an example provided by the present application, FIG8 shows a schematic diagram of a first data field provided by an embodiment of the present application. The typedef struct is an alias for defining an identifier and a keyword and has no specific meaning. The first data field, i.e., the data header of the first area, includes UserAndOwner (owner), FileType (file type), ValidFlag (validity), Reserve (reservation), FileSize (file size), and Crc (check value). Among them, UserAndOwner (owner) is the owner of the first area between the baseboard management controller and the basic input and output system. If the owner of the first area is the baseboard management controller, the basic input and output system cannot store strings in the first area; if the owner of the first area is the basic input and output system, the baseboard management controller cannot store strings in the first area. If there is no owner of the first area, both the baseboard management controller and the basic input and output system can store strings in the first area. When the baseboard management controller or the basic input and output system stores a string in the first area, the owner field needs to be modified to indicate the owner of the first area. FileType (file type) can indicate whether the first string is compressed. If the first string is compressed, FileType is 1; if the first string is not compressed, FileType is 1. ValidFlag indicates whether the second string is valid. When the BIOS finishes sending the second string to the baseboard management controller, ValidFlag is changed to 1, indicating that the second string is valid. When the baseboard management controller reads that ValidFlag has changed to 1, it begins parsing the second string. Reserve is a reserved field and has no meaning. FileSize indicates the size of the second string. Crc is the first checksum of the first string.

[0339] As an example provided by this application, Figure 9 shows a schematic diagram of the format of a second string provided in an embodiment of this application. Parameter name1 is a setting option, and Parameter value1 is the value corresponding to Parameter name1; Parameter name2 is a setting option, and Parameter value2 is the value corresponding to Parameter name2.

[0340] As an example provided by this application, Figure 10 shows a schematic diagram of the format of a fourth string provided in an embodiment of this application. The data format for a correct setting is {"Result":"EFI_SUCCESS"}; the data format for an incorrect setting is shown in Figure 10: Parameter name1 is the setting option, and the failure reason is the value corresponding to Parameter name1; Parameter name2 is the setting option, and the failure reason is the value corresponding to Parameter name2.

[0341] 11 shows a schematic flow chart of a basic input / output system sending a first setting option to a baseboard management controller according to an embodiment of the present application.

[0342] Step 1101, before entering the setting interface or after the user modifies the setting options, the basic input and output system collects the setting option data;

[0343] Step 1102 , the basic input / output system converts the setting option data into a Json (JavaScript Object Notation, a lightweight data exchange format) string format;

[0344] Step 1103, the basic input and output system calculates the string length and the check value;

[0345] In step 1104 , if the character string length is too large, the basic input / output system performs compression and sets the file type of the data header to 1; if it is still too large after compression, proceed to step 1109 .

[0346] Step 1105: The BIOS determines whether the shared memory is occupied. If the shared memory is occupied and the number of retries is less than 3, the BIOS sleeps for two seconds and re-determines whether the shared memory is occupied. If the number of retries is greater than 3, the BIOS proceeds to step 1109. If the shared memory is not occupied, the shared memory is occupied.

[0347] Step 1106, the basic input and output system writes the data header and the character string into the shared memory space;

[0348] Step 1107, the BIOS sets the validity field of the data header to 1;

[0349] Step 1108: The BIOS releases the shared memory.

[0350] Step 1109, end.

[0358] Step 1207: The baseboard management controller sets the validity field of the data header to 0;

[0359] Step 1208: The baseboard management controller releases the shared memory.

[0360] In step 1209, the baseboard management controller determines whether the file length is too long. If the file type is not too long, the process proceeds to step 1211. If the file length is too long, the process determines whether the file type is compressed. If the file type is compressed, the process proceeds to step 1210. If the file type is not compressed, the process proceeds to step 1216.

[0361] Step 1210 , the baseboard management controller decompresses the data;

[0362] Step 1211, the baseboard management controller determines whether the file verification is successful; if successful, proceed to step 1201; if failed, proceed to step 1216;

[0363] Step 1212: The baseboard management controller parses the Json string.

[0364] Step 1213: The baseboard management controller searches for BMC-related settings.

[0365] Step 1214: The baseboard management controller calls the corresponding settings of the relevant functional modules;

[0366] Step 1215: The baseboard management controller saves the Json string to the file cumrent_setting.jsom;

[0367] Step 1216, end.

[0369] Step 1301, start;

[0370] Step 1302: The BMC reads the data and checks whether the content format of future_setting.json is correct.

[0371] Step 1303: The baseboard management controller verifies whether the content format of future_setting.jaon is correct.

[0372] Step 1304: If the content format is correct, the baseboard management controller calculates the length and checksum of the Json file; if the content format is incorrect, proceed to step 1309;

[0373] Step 1305: The baseboard management controller determines whether the shared memory is occupied. If the shared memory is occupied and the number of retries is less than 3, the controller sleeps for two seconds and re-determines whether the shared memory is occupied. If the number of retries is greater than 3, the controller proceeds to step 1309. If the shared memory is not occupied, the controller occupies the shared memory.

[0374] Step 1306 , the baseboard management controller writes the data header and the character string into the memory space;

[0375] Step 1307: The baseboard management controller sets the validity field of the data header to 1;

[0376] Step 1308: The baseboard management controller releases the shared memory.

[0377] Step 1309, end.

[0378] 14 shows a schematic flow chart of a basic input / output system processing a second setting option according to an embodiment of the present application.

[0379] Step 1401, start;

[0381] Step 1403, the basic input and output system reads data;

[0382] Step 1404, the basic input and output system parses the data;

[0383] Step 1405, the basic input and output system verifies whether the parameters and parameter values ​​in the data are correct;

[0384] Step 1406: If the parameter and the parameter value in the verification data are correct, the basic input and output system stores the parameter in the corresponding location in the non-volatile storage medium; if the parameter and the parameter value in the verification data are incorrect, the parameter and the error cause are stored in an error list;

[0385] Step 1407, the basic input and output system determines whether the parameter in the verification data is the last parameter;

[0386] Step 1408, the basic input and output system structures the error list into a JSON format;

[0387] Step 1409: The basic input and output system converts the error list in the Json format into a string;

[0388] Step 1410, the BIOS puts the string into the shared memory;
