AP-485 - This Application Note
explains how to use the CPUID instruction in
software applications, BIOS implementations, and
tools. By taking advantage of the CPUID
instruction, software developers can create
software applications and tools that can execute
compatibly across the widest range of Intel
processor generations and models, past, present,
and future. New Intel processor signature and
feature bits information can be obtained from the
users manual, programmers reference manual or
appropriate documentation for a processor. In
addition, Intel can provide you with updated
versions of the programming examples included in
this application note; contact your Intel
representative for more information.
