Abstract
A computing device including a memory module. The computing device may further include a processor configured to, by executing instructions of an operating system, divide a non-volatile region of the memory module into a first non-volatile storage partition allocated to the operating system and a second non-volatile storage partition allocated to system firmware. The processor may write a globally unique identifier (GUID) to the non-volatile region. The GUID may indicate a location of a boundary between the first non-volatile storage partition and the second non-volatile storage partition. The processor may access the first non-volatile storage partition. By executing instructions of the system firmware, the processor may determine the location of the boundary. The processor may access the second non-volatile storage partition. The operating system may be prevented from accessing the second non-volatile storage partition and the system firmware may be prevented from accessing the first non-volatile storage partition.
