INSTRUCTION SET REFERENCE, A-M
CPUID—CPU Identification
do not support the brand identification feature. Starting with processor signature
family ID = 0FH, model = 03H, brand index method is no longer supported. Use
brand string method instead.
Table 3-19 shows brand indices that have identification strings associated with them.
