Abstract:
In a personal computing system function calls, formatted in 16-bit format for a 16-bit interface to the firmware, are communicated through an operating system providing a System Management Interrupt (SMI) interface to the firmware. An SMI function call in SMI format is generated and sent to an SMI Interface Wrapper module between the operating system and the firmware. The SMI function call is received over the SMI interface at the SMI Interface Wrapper. In the SMI Interface Wrapper, function data from the SMI function call is extracted to provide function call data. A 16-bit function call with the function call data is generated by the SMI Interface Wrapper and passed to the firmware.
