Re: Detecting if a CPU is an AMD Am486 or an Intel i486 from within Windows

FFD0 means: Model 3, Stepping 0. This does not even indicate the presence of a 486 processor at all. Wouldn't model 3 conform with DX=0430h at reset for a 486DX2? Ah, that makes sense as for it being a 486, that's easy , SYSTEM_INFO->wProcessorLevel is 3 for a 386, 4 for 486, 5 for Pentium and 6 …
