Ok, I see. Maybe I'm missing something, but does setting IA32_PQR_ASSOC when NEM mode is not enabled yet (for first setting it to 0x2) really do anything? My understanding was that the ways can't actually be protected until NEM mode is actually enabled, meaning that only the setting of 0x1 would "take effect". Could you help me understand this?
