For dimension drawing, the type, quantity and ratio of each element can be arbitrarily changed in actual implementation, and the layout of the element may also be more complicated.

In the basic input output system option modification method, system and device of the present invention, the baseboard management controller and the basic input output system communicate through Redfish, and the base input output system options are saved and modified through the baseboard management controller. Among them, after the basic input output system option is modified, the next time the basic input output system is started, the modified BIOS option will be matched and imported from the baseboard management controller and then restarted to take effect, thereby ensuring the safe and effective setting of the basic input output system option.

As shown in FIG. 1, in one embodiment, the BIOS option modification method of the present invention is applied to a BIOS, including the following steps:

Step S1, when starting up, read the setting values of each option of the basic input output system from the baseboard management controller.

Specifically, after the basic input output system is normally powered on, the setting values of various options in the basic input output system are stored in the baseboard management controller based on the Redfish interface. In an embodiment of the present invention, the setting values of the various options are stored in the baseboard management controller through a jason file. The jason file is stored in the jason buffer of the baseboard management controller. The basic input output system obtains the jason file stored in the Jason temporary register in the baseboard management controller through Rest Over IPMI Protocol.

At the same time, the user can modify the setting value of each option stored in the baseboard management controller. When booting again, the setting values of various options of the basic input output system are read from the baseboard management controller based on the Redfish interface. That is to say, when the power is turned on again, the setting value of each option in the baseboard management controller and the current value of each option in the basic input output system may be the same or may be different.

Step S2: Compare the current value of each option in the basic input output system with the corresponding set value, and when the current value is different from the set value, modify the current value to the set value.

Specifically, the basic input output system compares the current value and the set value of each option. Among them, first obtain the same option name, and then compare the current value and setting value corresponding to the option name. If the current value is consistent with the set value, it means that the option value of the BIOS has not been modified, and the boot is directly performed with the option value in the BIOS. If the current value and the set value are inconsistent, it means that the option value of the BIOS has been modified on the baseboard management controller, so the current value of the BIOS option is modified to the baseboard The corresponding setting value in the management controller is then started up, thereby ensuring the stability and reliability of the system.

As shown in FIG. 2 , in one embodiment, the BIOS option modification system of the present invention is applied to the BIOS, including a reading module 21 and an updating module 22 .

In an embodiment of the present invention, the setting values of the various options are stored in the baseboard management controller through a jason file. The jason file is stored in the jason buffer of the baseboard management controller. The basic input output system obtains the jason file stored in the Jason temporary register in the baseboard management controller through Rest Over IPMI Protocol.

At the same time, the user can modify the setting value of each option stored in the baseboard management controller. When booting again, the setting values of various options of the basic input output system are read from the baseboard management controller based on the Redfish interface. That is to say, when the power is turned on again, the setting value of each option in the baseboard management controller and the current value of each option in the basic input output system may be the same or may be different.

The update module 22 is connected with the reading module 21, and is used to compare the current value of each option in the basic input output system with the corresponding set value, and when the current value is different from the set value, all The current value is modified to the set value.

Specifically, the basic input output system compares the current value and the set value of each option. Among them, first obtain the same option name, and then compare the current value and setting value corresponding to the option name. If the current value is consistent with the set value, it means that the option value of the BIOS has not been modified, and the boot is directly performed with the option value in the BIOS. If the current value and the set value are inconsistent, it means that the option value of the BIOS has been modified on the baseboard management controller, so the current value of the BIOS option is modified to the baseboard The corresponding setting value in the management controller is then started up, thereby ensuring the stability and reliability of the system.
