That was my point. I think the idea Volker is suggesting is the micro-code updates go from AMD (who understands what the issue is with their processor) to the BIOS manufacturer (Phoenix or whoever did yous) and get incorporated in a secure way. They are 'known good' in the BIOS update we receive and write into a Flash drive. It's just a choice whether you want to use that part of BOIS or now. After all, _any_ BIOS update represents an opportunity for someone to really mess you machine up. Doesn't matter if it's micro-code or something else. That's my reading of this so far.... - Mark
