The present invention is a method and apparatus for providing storage of a significant number of events in a runtime event log without block erases of flash memory, through compression of multiple events within a single event entry. The compression of multiple events within a single log entry allows a significantly higher number of events to be stored within an event log than has heretofore been available, and thus provides more accurate information to a user performing diagnostic work on a computer system.

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.

Method and apparatus for protecting data using lock values in a computer

A request is received from a caller to perform a read of data from a storage area of a computer system, the data having master header data in a header portion. The master header data is replaced with alternate header data before returning the data to the caller. The data, including the alternate header data, is returned to the caller. A request is received from the caller to perform a write of caller data to the storage area, the caller data having caller header data in a header portion of the caller data. The write of caller data is allowed only if the caller header data is identical to the master header data.

Hidden headers for protecting computer system data

A status parameter is set for a storage area of a computer system to a read-only status. An access key is received from an access key call by a caller. The status parameter is changed to a write-permissible status if the access key matches a master access key. A request to perform a write to the storage area is received, and the write is allowed only if the status parameter has been set to the write-permissible status. The status parameter is reset to the read-only status after the write is performed.

Access key protection for computer system data

A request to erase a storage area of a computer system is received via an erase call by a caller, the erase call containing an erasure key. The storage area is erased only if the erasure key matches a master erasure key corresponding to the storage area. A request is received to perform a write to the storage area, and the write is allowed only if the storage area has been erased.
