Background technique

BIOS (Basic Input/Output System) is a set of programs solidified on the motherboard of the computer. It stores the most important basic input and output programs of the computer, the self-test program after power-on and the system self-starting program.

The BIOS provides a user interface for changing the configuration of the BIOS. The user modifies the configuration through the user interface provided by the BIOS to determine the initialization of the hardware and the boot sequence. In the server, the baseboard management controller of the server motherboard provides another user interface. The user interface provided by the baseboard management controller modifies the configuration to determine hardware initialization and boot sequence, etc. Therefore, a configuration synchronization function needs to be provided in the server to synchronize the modification of the BIOS configuration by the baseboard management controller and the BIOS user interface, specifically Yes, determine whether the configuration file of the baseboard management controller and the configuration file of the BIOS are modified, and synchronize the contents of the modified configuration file to another configuration file. Therefore, when two configuration files are modified at the same time, and the modified content is inconsistent, a synchronization conflict will occur; and during the synchronization process, if a configuration file is modified incorrectly, it will be synchronized and the error will be synchronized to another configuration file. Some computers have multiple boot hardware, such as some operating systems in the hard disk, some operating systems in the storage media connected by USB (Universal Serial Bus), and some operating systems in the PXE (Pre-Boot Execution Environment) port Connecting to the server, and the existing BIOS system needs to initialize all boot-related hardware when booting, causing the problem of slow booting speed.
