Embodiment 1
[0033] like figure 1 As shown, according to a firmware parameter configuration system 10 described in the embodiment of the present invention, the firmware parameter configuration system 10 includes built-in parameters, 101 and external parameter configuration files 102, wherein the built-in parameter table 101 is solidified in the firmware code , the external parameter configuration file 102 is not solidified in the code, the built-in parameter table 101 is generated when the firmware is compiled, and the external parameter configuration file 102 is generated by using the upper computer parameter configuration table generation software.
[0034] The firmware parameter configuration system 10 of the present embodiment is mainly used for initializing the CPU and peripherals etc. when the BIOS starts. It should be understood that the system on chip SOC (system on chip) is also used to perform work similar to the CPU, and the difference is only in the integration of the SOC. Othe...
Embodiment 2
[0059] refer to Figure 4 , the present embodiment provides a firmware parameter configuration device 30, which includes the following units:
[0060] A startup acquiring unit 31, configured to acquire startup operations;
[0061] A private key obtaining unit 32, configured to obtain the first private key from the read-only ROM in response to the startup operation;
[0062] The decoding parameter unit 33 is used to decode the built-in parameter table according to the first private key, and obtain the first parameter and the secondary private key;
[0063] The parameter obtaining unit 34 is used to decrypt the external parameter table using the secondary private key through the index to obtain the second parameter; wherein the external parameter table is the same as the internal parameter table of the firmware, and the second parameter is the same as the first parameter Constitute a complete hardware configuration parameter;
[0064] The configuration unit 35 is configured t...
Embodiment 3
[0070] refer to Figure 5 , an electronic device 20 , and this embodiment provides a schematic structural diagram of the electronic device 20 . The electronic device 20 of this embodiment includes a processor 21 , a memory 22 and a computer program stored in the memory 22 and executable on the processor 21 . When the processor 21 executes the computer program, the steps in the above-mentioned electronic method embodiments are implemented, for example image 3 Step S1 is shown.
[0071] Exemplarily, the computer program can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 22 and executed by the processor 21 to complete this invention. The one or more modules / units may be a series of computer program instruction segments capable of accomplishing specific functions, and the instruction segments are used to describe the execution process of the computer program in the electronic device 20 .
[0072] The electronic device 20 ...
