On the other hand, the jumper provided for setting these bios also reduces the available space on the motherboard, increasing the wiring restrictions of other components.

[ detailed description ] A
Fig. 1 is a schematic diagram illustrating a motherboard 100 according to an embodiment of the invention. As shown in fig. 1, the motherboard 100 includes a processing unit 110, a memory unit M2, and a Baseboard Management Controller (BMC) 130. The processing unit 110 is communicatively coupled to the memory unit M2 and the baseboard management controller 130. The memory unit M2 may be an Electrically Erasable Programmable Read Only Memory (EEPROM) or a Flash memory (Flash memory), and the memory unit M2 stores a jumper setup set JS0 and a jumper setup set JS2 preset by the BIOS 120 (BIOS 120). The bmc 130 is communicatively connected to the processing unit 110 and is configured to monitor and manage states, operations, and the like of various components on the motherboard 100, and the bmc 130 further includes a memory unit M1, where the jumper setting set JS1 is stored in the memory unit M1. In other embodiments, the Memory unit M1 may also be external to the bmc 130 and communicatively connected to the bmc 130 for the bmc 130 to Access data, and the Memory unit M1 may be a Static Random-Access Memory (SRAM) or an electrically erasable programmable read-only Memory (EEPROM) or a Flash Memory (Flash Memory).
In addition, the jumper setting groups JS0, JS1, and JS2 stored in the memory unit M1 and the memory unit M2 are used to store setting values for the user to enable or disable some functions or modes in the BIOS 120, and when the functions are enabled or disabled in the BIOS 120, for example, to clear the CMOS memory, clear the BIOS password setting, reply the BIOS, set the Management Engine (ME) to the reply mode, display the hidden BIOS option, enable the BIOS memory update, enable the network file sharing function, switch to the manufacture side mode (MFG mode), enable the host Video display (Console), and so on. In some embodiments of the present invention, a user can connect to a user interface through the bmc 130 (e.g., connect to a remote computer device for operation) to add or modify the setting values of the jumper setting group JS1 in the memory unit M1.
In the present embodiment, when the motherboard 100 is powered on, the processing unit 110 obtains the bios 120 from the memory unit M2 for execution. When the processing unit 110 executes the bios 120, the execution of the bios 120 determines whether the corresponding function is activated or not based on the jumper setting group JS1 of the memory unit M1. On the other hand, if the bios 120 cannot normally access the jumper set JS1 in the memory unit M1, it determines whether or not the corresponding function is activated according to the jumper set JS2 in the memory unit M2. On the other hand, if the jumper setting group JS2 is not stored in the memory unit M2, the bios 120 determines whether the corresponding function is activated according to the preset jumper setting group JS0 stored in the memory unit M2. Further ensuring that the bios 120 can function properly.
The following describes the operation flow of the bios setting method according to the present invention with reference to fig. 2 and fig. 1. After the motherboard 100 is powered on, in step S202, the processing unit 110 accesses the bios 120 in the memory unit M2 for execution.
Next, in step S204, the bios 120 executed by the processing unit 110 determines whether the jumper setting group JS1 of the memory unit M1 is accessible through the bmc 130. If yes, the process continues to step S206, and the processing unit 110 stores the setting value of the memory unit M1 in the memory unit M2 as the jumper setting set JS2. It should be appreciated that, when the motherboard 100 is first powered on, the memory unit M2 has not stored the jumper setting group JS2 and only stores the preset jumper setting value JS0, and until the processing unit 110 first executes step S206, the memory unit M2 stores the jumper setting group JS2 as a backup file of the current jumper setting group JS1. Next, at step S208, the processing unit 110 continues to execute the basic input output system 120 to start or close the corresponding function of the basic input output system 120 according to the setting values of the jumper setting group JS1.
On the contrary, when the bios 120 executed by the processing unit 110 cannot access the jumper setting group JS1 from the memory unit M1 through the bmc 130, the processing unit 110 determines whether the memory unit M2 stores the jumper setting group JS2 in step S210. If yes, continuing to step S212, the processing unit 110 accesses the jumper setting group JS2 in the memory unit M2, and continues to execute the bios 120 to start or stop the corresponding function of the bios 120 according to the setting value of the jumper setting group JS2. Otherwise, continuing to step S214, the processing unit 110 accesses the preset jumper setting group JS0 in the memory unit M2, and continues to execute the bios 120 according to the setting value of the jumper setting group JS0 to start or stop the corresponding function of the bios 120.
It should be understood that, in the embodiment, after the motherboard 100 is booted and the bios 120 is executed, if the user modifies the setting of the jumper setup group JS1 in the memory unit M1 through a user interface (not shown) connected to the bmc 130, the bmc 130 may further control the processing unit 110 to restart. Then, the processing unit 110 can execute the bios 120 according to the modified jumper setting group JS1. Therefore, the user can adjust the relevant settings of the bios 120 of the motherboard 100 through the remote host to meet the user's requirements, reduce the time required to calibrate the motherboard, and increase the efficiency of monitoring and adjusting. Furthermore, the present invention sets the setting value related to the jumper through software to replace the jumper of the actual hardware, thereby improving the management efficiency of the device, increasing the available space on the mainboard because the jumper of the actual hardware is not used any more, and reducing the design cost and the manufacturing cost of the mainboard.
Fig. 3 is a schematic diagram illustrating a motherboard 300 according to another embodiment of the invention. As shown in fig. 3, the main board 300 includes a processing unit 310, a memory unit M4, a board Management Controller 330 (BMC 330), and a jumper 340. Processing unit 310 is coupled to memory unit M4, baseboard management controller 330, and jumper 340. The Memory unit M4 may be a Static Random-Access Memory (SRAM), an Electrically Erasable Programmable Read Only Memory (EEPROM), or a Flash Memory (Flash Memory), and the Memory unit M4 stores a basic input/output system 320 (BIOS 320). The bmc 330 is communicatively connected to the processing unit 310 and configured to monitor and manage states, operations, and the like of various components on the motherboard 300, and the bmc 330 further includes a memory unit M3, and the memory unit M3 stores a jumper setting group JS3. In other embodiments, the memory unit M3 may also be external to the bmc 330 and communicatively connected to the bmc 330 for the bmc 330 to access data, and the memory unit M3 may be an Electrically Erasable Programmable Read Only Memory (EEPROM) or a Flash memory (Flash memory). Jumper 340 (Jumper 340) is used to provide a set of physical Jumper settings, and processing unit 310 can obtain the set of physical Jumper settings provided by Jumper 340 through general purpose input output pins (GPIOs), and a user can change the Jumper setting by changing the Jumper 340.
In the present embodiment, after the motherboard 300 is booted, the processing unit 310 obtains the bios 320 from the memory unit M4 for execution. When the processing unit 310 executes the bios 320, the executed bios 320 determines whether the corresponding function is activated or not based on the jumper setting group JS3 of the memory unit M3. On the other hand, if the bios 320 cannot normally access the jumper setting group JS3, it is determined whether the corresponding function is activated according to the physical jumper setting group of the jumper 340 instead.
The operation flow of the bios setting method of the present invention is described with reference to fig. 4 and fig. 3. After the motherboard 300 is booted, in step S402, the processing unit 310 accesses the bios 320 in the memory unit M4 for execution.
Next, in step S404, the bios 320 executed by the processing unit 310 determines whether the jumper setting group JS3 can be accessed from the memory unit M3 through the bmc 330. If yes, the process continues to step S406, and the processing unit 310 continues to execute the bios 320 according to the setting value of the jumper setting group JS3 to start or stop the corresponding function of the bios 320. On the contrary, when the bios 320 executed by the processing unit 310 cannot access the jumper setting JS3 from the memory unit M3 through the bmc 330, the processing unit 110 continues to step S408 by obtaining the physical jumper setting JS set by the jumper 340 through the general input output pin (GPIO), so as to start or stop the corresponding function of the bios 320.
In another embodiment, the memory unit M4 may also store a backup of the jumper setting set JS3, and if the bios 320 cannot normally access the jumper setting set JS3 in step S404, the backup jumper setting set of the memory unit M4 may also be attempted to be accessed. When the backup jumper setting group attempting to access the memory cell M4 also fails, step S408 is continued, and instead, whether the corresponding function is activated is determined according to the physical jumper setting group of the jumper 340.
In summary, after the motherboard 300 is powered on and the bios 320 is executed, if the user modifies the setting of the jumper setup group JS3 in the memory unit M3 through a user interface (not shown) connected to the bmc 330, the bmc 330 may further control the processing unit 310 to restart. Then, the processing unit 310 can execute the bios 320 according to the modified jumper setting group JS3. Therefore, the user can adjust the relevant settings of the bios 320 of the motherboard 300 through the remote host to meet the user's requirements, reduce the time required to calibrate the motherboard, and increase the efficiency of monitoring and adjusting. Furthermore, the present invention sets the setting value related to the jumper through software to replace the jumper of the actual hardware, thereby improving the management efficiency of the device, increasing the available space on the mainboard and reducing the design cost and the manufacturing cost of the mainboard because the jumper of the actual hardware is not used.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
