ABSTRACT:
A method and apparatus for protecting data using lock values in a computer system includes indicating that the computer system does not support locked accesses to the data. However, upon receipt of a request to write to the storage area where the data is contained, the present invention checks whether a lock value corresponding to the request matches a predetermined lock value. If the lock value matches the predetermined lock value, then the data is written to the storage area; otherwise, the storage area is left unmodified.
