The BIOS booting block of the SPI ROM is locked in a normal operating state of the computer system, and the main BIOS is checked to determine whether the main BIOS is damaged when the computer system is powered on. The BIOS booting block of the SPI ROM is unlocked when the main BIOS is damaged, and the BIOS booting block is enable to recover the main BIOS according to a backup BIOS stored in the storage device. After the main BIOS has been recovered successfully, the computer system boots normally and enters an operating system (OS) successfully.
