typedef struct _SYSTEM_INFO { // sinf
    union {
        DWORD  dwOemId;
        struct {
            WORD wProcessorArchitecture;
            WORD wReserved;
        };
    };
    DWORD  dwPageSize;
    LPVOID lpMinimumApplicationAddress;
    LPVOID lpMaximumApplicationAddress;
    DWORD  dwActiveProcessorMask;
    DWORD  dwNumberOfProcessors;
    DWORD  dwProcessorType;
    DWORD  dwAllocationGranularity;
    WORD  wProcessorLevel;
    WORD  wProcessorRevision;

} SYSTEM_INFO;


All values seem to be nonsense.
wProcessorRevision is 1536 on Athlon 1.8+.

Thanks,
