Hi, ive got an Question about how to manipulate CPUID

the source to detect mmx is :

bool isMMXSupported()
{
int fSupported;
__asm
{
mov eax,1 // CPUID level 1
cpuid // EDX = feature flag
and edx,0x800000 // test bit 23 of feature flag
mov fSupported,edx // != 0 if MMX is supported
}
if (fSupported != 0)
return true;
else
return false;
}

And now my Question: How can I manipulate CPUID to
be MMX bit = 0 ?

Any help would be appreciated ...

Thanks in Advance.
