How do I determine if a CPU supports Uniprocessors/Multiprocessors or only ACPI

[cwalker]

I have an application I'm supporting that needs to determine whether or
not a CPU supports Uni/Multi-processors or just ACPI. The original
developer determined this by testing the CPUID features bits against
0xBFF(Uni/Multi support) and 0x9FF (ACPI only support).

This doesn't seem to be working properly with some of the newer Intel
Chipsets (i915M, i945M, etc).

I know very little about the CPUID and the feature sets. I was
wondering if anyone out there could help me understand this and
hopefully help me figure out a more reliable way to make this
determination.

Thanks!

And your C++ language question would be? Please see:

I guess my C++ question would be: Using C++, how do I determine whether
or not the CPU supports Uniprocessors/Multiprocessors or just ACPI?

The answer to your question is "there is no means in C++ language and
library to do that". You need to use OS-specific mechanism for that.
