Abstract
A basic input/output system (BIOS) protection method capable of preventing computer virus attack. The method includes setting up a protection function in the basic input/output system. The protection function enables a user to select between protection enable and protection disable. When protection enable is selected, only reading from a set memory holding the BIOS program is permitted. Hence, nothing can be written into the memory. Conversely, if protection disable is selected, data can be written into the set memory. Since protection disable can be selected by user at any time, protection enable is selected by default so that the writing of data into the BIOS memory by computer viruses is prevented.
Claims6
A method of protecting a basic input/output system against computer virus attack, comprising the steps of:
- setting up a protection function in the basic/input output system, wherein the protection function provides user with a choice of selecting between a protection enable state and a protection disable state;
- permitting only the reading of data from a memory for holding BIOS data when the protection enable state is selected so that the writing of data into the memory is disallowed;
- and
- permitting the writing of data into the memory when the protection disable state is selected.
