COMPUTING DEVICE AND METHOD FOR AUTOMATICALLY RECOVERING BIOS OF COMPUTING DEVICE

摘要

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.

主权项

1. A computing device, comprising:
a serial peripheral interface (SPI) ROM configured to store a first basic input-output system (BIOS) booting block and a main BIOS; a supper I/O (SIO) controller configured to store a second BIOS booting block; and a storage device configured to store a computer-readable program comprising instructions that, when executed by at least one processor, cause the at least one processor to: check an integrity of the main BIOS when the computing device is powered on; determine whether the main BIOS is partially or fully damaged according to the checking result; power on the computing device using the first BIOS booting block when the main BIOS is partially damaged; power on the computing device using the second BIOS booting block when the main BIOS is fully damaged; and read a backup BIOS stored in the storage device, and write the backup BIOS into the SPI ROM to update data of the main BIOS by transmitting a copy of the backup BIOS from the storage device to the SPI ROM.
