ABSTRACT:
A method for protecting a BIOS from unauthorized modifications includes the steps of: providing a password storing region (122) configured for storing a first password of the BIOS; copying the first password from the password storing region into a CMOS RAM (10); determining whether the first password of the BIOS needs to be changed; receiving and verifying a verifying password inputted by a user with the first password for preventing an unauthorized user to change the first password if the first password needs to be changed; setting a new password of the BIOS if the verifying password is valid, and storing the new password into the CMOS RAM; copying the new password from the CMOS RAM into the password storing region. A system for protecting a BIOS from unauthorized modifications is also disclosed.
