Abstract
A system and method to virtualize BIOS, including run time services. A processing system has a processor, a memory system with a predefined physical address space, a storage medium, and a communication medium between the processor and the storage medium. The processing system is operable in a pre-execution environment in which a specified portion of the physical address space is used to map basic input/output system (BIOS) run time service routines. The specified portion contains RAM memory. A BIOS virtualization system includes an image of the BIOS processor-executable instructions on the storage medium and processor-executable instructions that retrieve the BIOS image from the storage medium and store the BIOS image into the RAM memory mapped into the second specified portion of physical address space.
