Hmmm..now lets see...
Centrino = Carmel = Banias (Processor Code Name) + 855 chipset + 2100 wireless
Centrino = Carmel = Dothan (Processor Code Name) + 855 chipset + 2200 wireless
Centrino - Second Generation = Sonoma = Dothan 533MHz FSB + Alviso 915 chipset + Calexico 2915 wireless
If you haven't oredred an Intel Wireless card, you won't get a Centrino Sticker, instead you'll get a Pentium M sticker. Bottomline, if you have Dothan 1.60+ MHz @ 533 FSB and a Wireless card, you have Sonoma Platform.
? Let me know and I'll try to translate it all in english
