Appeal No. 1998-1104
Application No. 08/380,985
dependent code for implementing a plurality of functions
comprising an applications program interface (API). The
system memory is comprised of secure memory space and
nonsecure memory space.
Claim 1 is illustrative of the claimed invention, and
reads as follows:
1. In a computer system comprising system memory and a
processor capable of operating in a system management mode
(SMM), a method for enabling the optimization of the location
in said system memory of machine-dependent code for
implementing a plurality of functions comprising an
applications program interface (API), a portion of said system
memory comprising secure memory space accessible only while
said SMM is invoked, the method comprising:
storing code for implementing less than all of said
plurality of functions in said secure memory space;
storing code for implementing each of the remaining ones
of said plurality of functions in memory space other than said
secure memory space;
responsive to an applications program calling one of said
plurality of functions, determining whether code for
implementing said called one of said plurality of functions is
stored in said secure memory space;
responsive to a determination that said code for
implementing said called one of said plurality of functions is
stored in said secure memory space;
invoking said SMM;
executing said code for implementing said called one
of said plurality of functions; and
