The above and other objects, features, advantages and embodiments of the present disclosure will become more apparent and understood. 1 is a schematic diagram showing a set value recovery system according to an embodiment of the present disclosure; and FIG. 2 is a flow chart showing a method for restoring a set value according to another embodiment of the present disclosure.

To make the description of the present disclosure more detailed and complete, reference is made to the drawings and the various embodiments described below. The examples are not intended to limit the scope of the invention; the description of the steps is not intended to limit the order of execution thereof, and any device having equal efficiency resulting from recombination is covered by the present invention. range.

In the scope of the embodiments and claims, unless the context specifically dictates the articles (for example, "single" means only one number), "a" and "the" can mean a single or plural.

In addition, as used herein, "coupled" and "connected" may mean that two or more elements are in direct physical or electrical contact with each other, or indirectly in physical or electrical contact with each other. "Connected" may also mean that two or more elements operate or interact with each other.

1 is a schematic diagram of a set value recovery system 100 in accordance with an embodiment of the present disclosure. The set value recovery system 100 includes an operation control module 110 and a substrate management control module 120. The substrate management control module 120 is electrically coupled to the operation control module 110. The baseboard management control module 120 includes an application programming interface (API) unit 122, an initialization instruction storage unit 126, and a message handler (Message). Handler) unit 124. The setpoint recovery system 100 can be applied to a computer system, such as a server system.

In order to restore the user identification code to the factory default state, the message handler unit 124 is used to define and initialize the variables to a first value (eg, 0) and continuously monitor the variables. The operation control module 110 invokes the first set value recovery command on the substrate management control module 120, wherein the first set value recovery instruction is, for example, a single Original Equipment Manufacturer (OEM) instruction. The application interface unit 122 of the baseboard management control module 120 sends a single original equipment manufacturer (OEM) command to the message handler unit 124 upon receipt of a single original equipment manufacturer (OEM) command. When the message handler unit 124 determines that a single original device manufacturer command transmitted by the application interface unit 122 is received as a valid command, the set variable is a second value (eg, 1). When the message handler unit 124 detects that the variable is the second value, the initialization instruction set stored in the initialization instruction storage unit 126 is called to set the user identification (User ID, User ID) of the substrate management control module 120. Restore to the factory default state. For example, the message handler unit 124 invokes an initialization instruction set to restore one of the user name, password, and rights, or a combination thereof, to the factory default state. In addition, after the recovery process ends, the message handler unit 124 sets the variable to a first value (eg, 0) to avoid repeatedly detecting that the variable is the second value and repeatedly executing the recovery procedure. The above user names, passwords and permissions are for illustrative purposes only and are not intended to limit the invention, and other system settings are also within the scope of the present disclosure. In practice, a single original equipment manufacturer's instructions may refer to a single instruction defined by the original equipment manufacturer, the content of which It can be flexibly designed according to actual needs. In this example, the above-mentioned processing procedures are all completed in the memory of the substrate management control module 120 without the need of an external interface, thereby improving efficiency and reducing the chance of errors.

System users can include custom users and preset users. In an embodiment, the initialization instruction storage unit further includes a deletion instruction set, and the deletion instruction set is used to delete the user defined by the user and the set value thereof, that is, the custom user.

In an embodiment, the initialization instruction set preset by the substrate management control module 120 in the initialization instruction storage unit 126 may be multiple Intelligent Platform Management Interface (IPMI) instructions for the message processor unit. 124 judges that receiving a single original equipment manufacturer manufacturer instruction is a valid instruction, and detecting when the variable is the second value. For example, the operation control module 110 only needs to send a single original equipment manufacturer manufacturer instruction to the substrate management control module 120. When the message processor unit 124 determines that it is a valid instruction, the setting variable is set to a second value (for example, 1). . When the message processor unit 124 detects that the variable is the second value, the user name IPMI command and password wisdom preset by the baseboard management control module 120 to the initialization command storage unit 126 can be executed. The User Password IPMI command and the User Access IPMI command restore the user ID to the factory default state. In other words, the single original equipment manufacturer's instruction has the function equivalent to the user name smart platform management interface command, the password smart platform management interface command and the authority smart platform management interface command, because This only needs to send a valid single original equipment manufacturer manufacturer command to the baseboard management control module 120 to restore the user name, password and authority to the factory default state respectively. Compared with the prior art, it is necessary to call the smart platform management interface instruction corresponding to different settings (such as user name, password, permission or other settings) to modify User ID1 and User ID2, and then send other instructions to delete the remaining user messages, so the total is sent. The number of instructions can be as high as dozens, not only inefficient, but also easy to make errors when calling instructions between different interfaces, resulting in system failure. Therefore, the present invention can achieve the function of the instruction required to restore the set value by calling a single original equipment manufacturer instruction, and through a single application interface call, not only improves the efficiency of instruction execution, but also reduces the probability of occurrence of errors. . When the message processor unit 124 detects that the variable is the second value, the pre-set smart platform management interface command may be designed as other multi-smart platform management interface commands according to actual requirements.

For example, in a server system, the preset state of the substrate management control module 120 is two user identification codes User ID1 and User ID2, and the user name and password of the user identification code User ID1 are set to an empty user name. (Null user name), and its status is Enable. The user ID User ID2 user name and password are both set to admin, the status is Enable, and has Administrator privileges. The above preset state of the factory is for illustrative purposes only, and is not intended to limit the present invention, and other factory preset states are also covered by the present disclosure.

The first set value recovery instruction of the present disclosure may be invoked via different interfaces to restore the user identification code to a factory preset state. In one implementation For example, the operation control module 110 includes a basic input/output system (BIOS) unit 112 and a user interface (UI) device 114, wherein the basic input/output system unit 112 and the user interface device 114 The application interface unit 122 is electrically coupled. The first set value recovery command may be issued by the basic input output system unit 112 or the user interface device 114 to the application interface unit 122. For example, the first set value recovery command sent by the basic input/output system unit 112 may be a system embedded command, and the first set value recovery command sent through the user interface device 114 may be a user input command. In practice, the user interface device 114 can include a display screen of a touch display screen or a multi-touch display screen, a keyboard or other input device, a microphone, a speaker, and the like.

To specifically describe the message handler unit 124, in one embodiment, the message handler unit 124 includes a detection unit (Subunit) 222, a flag sub-unit 224, and an execution sub-unit 226, wherein the detection sub-unit 222 is electrically The application sub-unit 122 is coupled to the initialization instruction storage unit 126. The above variables are defined by the marking sub-unit 224 and initialized to a first value (e.g., 0).

For convenience of explanation, the user sends the first set value recovery command through the user interface device 114 as an example. The user can send a first set value recovery command (for example, a single original equipment manufacturer command) to the application interface unit 122 of the baseboard management control module 120 through the user interface device 114 to restore the user identification code to the factory preset. status. The application interface unit 122 of the substrate management control module 120 receives the user interface device After a single original equipment manufacturer command is sent 114, a single original equipment manufacturer (OEM) command is sent to the detection determination sub-unit 222 of the message processor unit 124. The detection judging unit 222 is configured to poll the single original equipment manufacturer command transmitted by the detection receiving application interface unit 122 and determine whether the single original equipment manufacturer manufacturer instruction is valid. When the detection determination sub-unit 222 determines that the single original equipment manufacturer command is valid, the second set value recovery command is output to the mark sub-unit 224. When the marking sub-unit 224 receives the second set value recovery command, the set variable is set to a second value (for example, 1). On the other hand, when the detection judging unit 222 judges that the single original equipment manufacturer instruction is invalid, intercepts a single original equipment manufacturer instruction and generates a first response message (for example, a single original equipment manufacturer instruction execution failure message). When the execution sub-unit 226 detects that the variable is the second value, the execution sub-unit 226 calls the user name initialization instruction, the password initialization instruction, and the permission initialization instruction of the initialization instruction storage unit 126, respectively, to at least one user name, at least one password and At least one authority is restored to a corresponding preset value, and a second response message is generated (eg, a single original equipment manufacturer instruction execution success message). In the case where a single original equipment manufacturer command is invoked through the user interface device 114, after the substrate management control module 120 generates a response message (eg, a first response message or a second response message), the user interface device 114 further proceeds from The baseboard management control module 120 receives the response message to display information about the success or failure of the recovery procedure on the user interface device 114. Therefore, the user can know whether the operation of restoring the user identification code of the substrate management control module 120 to the factory preset state is successful. In addition, after the recovery process ends, the message handler unit 124 sets the variable to a first value (eg, 0) to avoid detecting the variable to the second value again. Repeat the recovery process. In this example, the above-mentioned processing procedures are all completed in the substrate management control module 120 without the need of an external interface, thereby improving efficiency and reducing the chance of errors.

The following describes an example of the detection determination sub-unit 222 determining whether the first set value recovery command is valid. The detection determination sub-unit 222 compares the received first set value recovery command with a standard command stored in advance in the substrate management control module 120. If the first set value recovery command is identical to the standard command, the detection determination sub-unit 222 determines that the first set value recovery command is valid. On the other hand, if the first set value recovery command is inconsistent with the standard command, the detection determination sub-unit 222 determines that the first set value recovery command is invalid.

To specifically illustrate the implementation of the standard instructions, in one embodiment, when the first set value recovery command (eg, a single original equipment manufacturer command) is sent by the user interface device 114, the single original equipment manufacturer command includes the detect Wrong message. When the message processor unit 124 receives the single original equipment manufacturer's instruction, the detection and determination sub-unit 222 is consistent with the single original equipment manufacturer's instruction and the standard instruction, for example, checking whether the error information of the two is correct. If the detection determination sub-unit 222 determines that the debug information is correct, the flag sub-unit 224 sets the variable to a second value (for example, 1), and the execution sub-unit 226 further restores the user name, password, and authority to the corresponding preset values, respectively. On the other hand, if the detection determination sub-unit 222 determines that the error detection message is incorrect, the marking sub-unit 224 does not set the variable to the second value, that is, the execution sub-unit 226 does not restore the user identification code to the factory preset state, and The detection judging unit 222 generates a response message representing the failure of execution.

For example, the first set value recovery command (eg, a packaged single original equipment manufacturer's instruction) is (30h, CEh) followed by three Bytes of debug messages. The purpose of the debug message setting is to prevent the user from inadvertently calling the single original device manufacturer command through the user interface device 114, and the user-defined user name, password and authority are invalidated due to being restored to the factory default state. . Therefore, when a single original equipment manufacturer's instruction is invoked, the correct debug message must be entered in order to properly call the resume command to restore the factory default state. Otherwise, entering the correct single original equipment manufacturer's instructions and the wrong debug message will not successfully restore the user ID to the factory default. Debug messages, such as code for making information, are sorted by Least significant byte first. In the present embodiment, the debug message is set to a code for manufacturing information Inventec, such as the Internet Assigned Numbers Authority (IANA) code "0019a9h". After the recovery procedure ends, a one-character response message is generated to indicate that the recovery program was successful or failed. The above character lengths, instruction codes and message codes are merely illustrative and are not intended to limit the invention. Other suitable character lengths, instruction codes and message codes are also within the scope of the present invention.

In practice, the substrate management control module may be a Baseboard Management Controller (BMC). The basic input/output system unit 112, the application interface unit 122, the message processor unit 124, the initialization instruction storage unit 126, the detection determination sub-unit 222, the marking sub-unit 224, the execution sub-unit 226, etc., as described above, The specific embodiment may be a soft body, a hard body and/or a firmware. For example, if the execution speed and accuracy are the primary considerations, the modules, units, and sub-units can basically be dominated by hardware and/or carcass; if design flexibility is the primary consideration, The module, each unit, and each sub-unit are basically software-based; or, each module, each unit, and each sub-unit can simultaneously work with software, hardware, and carcass. It should be understood that the above examples are not intended to limit the present invention, and are not intended to limit the present invention. Those skilled in the art will be able to flexibly select modules, units, and subunits as needed. Specific implementation.

2 is a flow chart illustrating a set value recovery method 200 in accordance with another embodiment of the present disclosure. The set value recovery method 200 includes a plurality of steps S202 to S214, which can be applied to the set value recovery system 100 as shown in Fig. 1, but those skilled in the art should understand the steps mentioned in the present embodiment. Except for the order in which they are specifically stated, they can be adjusted according to actual needs, and can even be executed simultaneously or partially.

First in step S202, the variable LOADUSER is defined, and the value of the variable LOADUSER is set to the first value (for example, 0) during the initialization. In step S204, it is determined whether the received first set value recovery instruction is a valid instruction, wherein the first set value recovery instruction is, for example, a single original equipment manufacturer instruction, used to restore the user identification code to a factory default state. . If it is determined that the received first set value recovery command is a valid command, then in step S206, the set variable LOADUSER is set to a second value (for example, 1). On the other hand, if the first set value recovery command is not received, or if the received first set value recovery command is not a valid command, the number is not changed. The value of LOADUSER, and in step S214, a first response message is generated (e.g., the first set value resume instruction execution failure message). Next, in step S208, it is determined whether the value of the variable LOADUSER is the second value (for example, 1). If the value of the variable LOADUSER is the second value (for example, 1), indicating that the first set value recovery command is a valid command, then in step S210, the user name, password, and authority are respectively restored to the corresponding preset by the baseboard management control module. value. In step 212, a second response message is generated to indicate that the first set value recovery command is successfully executed. After the execution of step S210 is completed, the process returns to step S202 to set the variable LOADUSER to the first value (for example, 0) to avoid repeatedly detecting that the variable is the second value and repeatedly executing the program restored to the preset value. On the other hand, if the value of the variable LOADUSER is determined to be non-second value (for example, 0) in step S208, it means that the first set value recovery instruction is not received, or the first set value recovery instruction is not a valid instruction, and then return to Step S204 further determines whether the received first set value recovery instruction is a valid instruction.

In one embodiment, the first set value recovery instruction, exemplified by a single original equipment manufacturer manufacturer, has a function equivalent to a plurality of smart platform management interface instructions. For example, if it is determined in step S204 that the first set value recovery command is received as a valid command (eg, transmitted through the basic input/output system unit or the user interface device), the variable LOADUSER may be set to the second value in step S206. (eg 1). In the above step S208, when it is determined that the value of the variable LOADUSER is the second value (for example, 1), the preset user name smart platform management interface command and the password smart platform management interface are invoked through the substrate management control module in step S210. Command and Permissions Wisdom Platform Management Interface Command to restore user name, password and permissions Revert to the corresponding preset value. In other words, the single original equipment manufacturer's instruction has the function equivalent to the user name smart platform management interface command, the cryptographic smart platform management interface command and the privilege smart platform management interface command, so only a single original equipment manufacturer instruction is required to be sent. You can restore the user name, password, and permissions to the factory default state. Compared with the prior art, it is necessary to call the smart platform management interface instruction corresponding to different settings (such as user name, password, permission or other settings) to modify User ID1 and User ID2, and then send other instructions to delete the remaining user messages, so the total is sent. The number of instructions can be as high as dozens, which is not only inefficient, but also easy to make errors when calling instructions between different interfaces, resulting in system failure. Therefore, the present invention can achieve the function of the instruction required to restore the set value by calling a single first set value recovery command, and through a single application interface call, not only improves the efficiency of instruction execution, but also reduces the probability of error occurrence. . The above-mentioned smart platform management interface command executed in step S210 can also be designed as other multi-smart platform management interface instructions according to actual needs.

The single original equipment manufacturer's instructions of the present disclosure may also be invoked via different interfaces to restore the user identification code to the factory preset state, that is, the factory user preset value. In one embodiment, the user can send a single original equipment manufacturer command through the user interface device to restore the user identification code to the factory preset state. After receiving a single original equipment manufacturer command sent by the user interface device and determining to be a valid command, the set variable LOADUSER is set to a second value (for example, 1). When the variable LOADUSER is detected as the second value, the user identification code is restored to the factory preset state through the baseboard management control module. For example, the user name, password, and permissions are One or a combination thereof is restored to the factory default state, and a response message is generated after the recovery procedure ends to represent success or failure of the recovery program execution. In the case where a single original equipment manufacturer command is invoked through the user interface device, after the response message is generated, the response message is further received through the user interface device to indicate that the success or failure of the recovery program is on the user interface device. Therefore, the user can know whether the restoration of the user identification code to the factory preset state is successful.

In another embodiment, the step S204 may be performed to determine that the first set value recovery command sent by the user by using the user interface device is received and compared with the pre-stored standard command, that is, whether the debug information is correct. . If the comparison is the same, that is, the first set value recovery command sent by the user interface device is received and the debug message is correct, the variable LOADUSER is set to the second value (for example, 1) in step S206. If the first set value recovery command sent by the user interface device is not received or the comparison is inconsistent (that is, the debug message error), the original value of the variable LOADUSER is maintained. For example, the first set value recovery command (eg, a packaged single original equipment manufacturer's instruction) is (30h, CEh) followed by a three-character debug message. The purpose of the debug message setting is to prevent the user from inadvertently calling the above-mentioned single original device manufacturer command, and the user-defined user name, password and authority are invalidated due to returning to the factory default state. Therefore, when a single original equipment manufacturer's instruction is invoked, the correct debug message must be entered in order to properly call the resume command to restore the factory default state. Otherwise, entering the correct single original equipment manufacturer's instructions and the wrong debug message will not successfully restore the user ID to the factory default. Debugging information such as about The code that creates the information and sorts it with the least significant character. In the present embodiment, the debug message is set to a code for manufacturing information Inventec, such as the Internet Assigned Numbers Authority (IANA) code "0019a9h". After the recovery procedure ends, a one-character response message is generated to indicate that the recovery program was successful or failed. The above character lengths, instruction codes and message codes are merely illustrative and are not intended to limit the invention. Other suitable character lengths, instruction codes and message codes are also within the scope of the present invention.

In summary, the present disclosure can complete the function of restoring the user identification code setting value of the substrate management control module in the system by sending a single command through the basic input/output system or the user interface device. The setting of the debug message prevents the recovery command from being erroneously invoked and the user ID defined by the system user is invalidated. Therefore, the present disclosure can achieve the function of executing a plurality of instructions required to restore the user identification code set value by calling a single instruction. Therefore, the operation of the instruction call is simplified, and at the same time, efficiency and security are improved.

Although the present disclosure has been disclosed in the above embodiments, it is not intended to limit the invention, and the present invention may be modified and retouched without departing from the spirit and scope of the present disclosure.
