US 2012/0239920 A1 · APPROACHES FOR UPDATING BIOS

Abstract

Approaches for updating a Basic Input/Output System (BIOS) program used in a computer system. The computer system includes a central processing unit (CPU) and a non-volatile memory. The non-volatile memory is used to store the BIOS program, and the BIOS program includes a booting area and a program area for storing a first BIOS image file. The update method includes: duplicating a second BIOS image file from an external storage device of the computer system to a designated area of an internal non-volatile storage device of the computer system; changing a flag from a first status to a second status after the duplication is completed; checking the status of the first BIOS image file when the computer system is booted; and booting the computer system by the first BIOS image file or the second BIOS image file according to the status of the first BIOS image file.

Dependent claims

A computer system having a Basic Input/Output System (BIOS), externally connected to a storage device, the computer system comprising:

a central processing unit (CPU);
a first storage unit for storing a BIOS program, wherein the BIOS program comprises a booting area and a program area used to store a first BIOS image file;
a second storage unit;
a controller, electrically connected between the second storage unit and the storage device, and used to duplicate a second BIOS image file in the storage device to a designated area in the second storage unit;
and
a third storage unit for storing a flag;
wherein after the second BIOS image file is duplicated into the designated area, the flag is changed from a first status to a second status;
wherein the CPU checks the status of the first BIOS image file, and determines whether to boot the computer system by the first BIOS image file or the second BIOS image file according to the status of the first BIOS image file.
