From the wiki: "It is necessary to check whether the feature is supported by the CPU by issuing CPUID with EAX = 80000000h first and checking if the returned value is greater or equal to 80000004h."

I know that in this way i'll find out: is Brand string supported or not? But i need the list of old AMD CPUs which do not support this function. I'm writting CPUID program. If they don't have the Brand string function so i must recognize them by signature. Need to know their names and signatures. Does anyone know where i find such informations?
