Well, I believe those bits are directly reflecting the fuses/straps programmed (the sames that will actually disable hw), so it should be better than VBT. On the other hand, that's the reason why I only check from IVB on and not from ILK to not take unecessary risks on platforms with no known fused config. In any case, if someone with such a device could test the series :) -- Damien
