More Information
Summary:The invention discloses a BIOS (Basic Input/Output System) backup and restoration method based on a single SPI (Serial Peripheral Interface) Flash chip, which comprises the following steps of: dividing the single SPI Flash chip into two storage areas, namely a BIOS space and a mirror image space; when the backup function needs to be realized, the BIOS setup is firstly entered, then the backup function is selected, the BIOS Image is stored in the mirror image space or the USB flash disk, and when restoration needs to be carried out, restoration is carried out through the mirror image space or the USB flash disk. One Flash chip is divided into two storage areas, the functions of backing up and restoring the BIOS in the same Flash chip are achieved, materials are saved, a chip selection circuit is not needed, the implementation complexity is relatively low compared with a traditional BIOS backup and restoration mode, meanwhile, configuration of the BIOS can be backed up at any time, and the BIOS does not need to
