    initial v1  
    1 Note that according to clause 4.1 of "Intel Processor Identification and CPUID function" application Note 485 [http://www.intel.com/Assets/PDF/appnote/241618.pdf] "Beginning with Pentium III processors the processor identification was further extended with addition of Brand ID". At the current state of CPU identification n Haiku OS only extended family, extended model, family and model values are taken into account. Looks like the mentioned CPU mis-identification can be correctly fixed only by adding Brand ID to corresponding cpu_type defines.
