A method and apparatus described herein are for providing a simplified option Read Only Memory (ROM) that is compatible in multiple firmware and platform architectures. Instead of providing multiple option ROM images for every variation of platform architecture and firmware architecture, a single code image is provided along with an interpreter stub. If the default code type of the code image is supported by a platform, then the option ROM is directly launched from the single code image without launching the interpreter stub. However, if a device including the option ROM is inserted in a different variation of platform or firmware architecture that does not support the single code image code type, then the interpreter is launched, which in turn interprets, translates, and/or launches the single code image. |
