ABSTRACT:
System management mode (SMM) is utilized, despite operating system security measures, by furnishing a polled interface for SMM. When an application program is to make an XBIOS call, the application program posts an XBIOS request in a storage. SMM is activated periodically by a timer and, during activation, checks the storage for XBIOS requests. When an XBIOS request is posted, SMM processes the request XBIOS command and leaves a response from the XBIOS call in the storage. The application program, which continually loops, monitors the storage and detects replacement of the XBIOS request by the XBIOS result to realize completion of an XBIOS call.
