Abstract
In a method for automatically recovering a basic input-output system (BIOS) of a computing device, the computing device includes a serial peripheral interface (SPI) ROM, a storage device, and a supper I/O (SIO) controller. The SPI ROM stores a first BIOS booting block and a main BIOS, and the SIO controller stores a second BIOS booting block. An integrity of the main BIOS stored in the SPI ROM is checked when the computing device is powered on. The first BIOS booting block boots the computing device when the main BIOS is partially damaged, and the second booting block powers on the computing device when the main BIOS is fully damaged. A backup BIOS is obtained from the storage device, and is written into the SPI ROM to update data of the main BIOS.
