Systems and methods provide for emulating a host architecture in guest firmware. One aspect of the systems and methods comprises determining whether an emulated instruction would cause a transition into a legacy mode. A current execution context is converted into a legacy mode context, and the firmware emulator proceeds to a group of legacy mode instructions in a native mode for the processor. The firmware emulator detects an end instruction and converts the legacy context back to the guest firmware context. |
