I can't remember which systems were affected. Ok, now AMD people: what's the story with IO ECS, can we assume that on everything after F10h, BIOS has a sensible MCFG and we can limit this to F10h only? I like Bjorn's idea but we need to make sure a working MCFG is ubiquitous. Which begs the real question: Suravee, why are you even touching IO ECS provided F15h and later have a MCFG?
