  • Method and apparatus for executing real-mode interrupts from within extended SMRAM handler
    Patent number: 6694401
    Abstract: Embodiments of the present invention provide for executing real-mode interrupts from within an extended SMRAM handler. If there is a need to make a real-mode call from the extended SMRAM handler, control is transferred to a compatible SMRAM region and appropriate calls to the real-mode calls are executed from within the compatible SMRAM region. The call from the extended SMRAM handler code to the compatible SMRAM code switches the processor from protected mode to real-mode. After the real-mode call is complete, control is returned to the compatible SMRAM handler. The processor is placed back into protected mode and control transferred back to the extended SMRAM handler code.
