Abstract
A BIOS updating method determines whether to allow a current BIOS version to be upgraded or downgraded to a target BIOS version according to a dependency description recorded in a BIOS updating program or a dependency description recorded in an SMBIOS. If all of the BIOS versions recorded in the dependency description are not between the current BIOS version and the target BIOS version, the BIOS updating program allows the current BIOS version to be upgraded or downgraded to the target BIOS version. If at least one of the BIOS versions recorded in the dependency description is between the current BIOS version and the target BIOS version, the BIOS updating program forbids the current BIOS version to be directly upgraded or downgraded to the target BIOS version.
