I did some searching at cpu world and basically
06A1-06A5 are Nahalem CPUID’s → useless for Z77
06A6 is only for mobile i7-2720QM SB ES/QS cpu → useless for Z77
06A8 is only for some mobile IVB ES/QS cpus → useless for Z77
So I will leave only 06A7_28 and 06A9_19
Alternatively, this is done automatically by UBU (leaves only 06A7 and 06A9).
