I don't know if it is model specific or motherboard specific. Considering how bad this bug is (causing artifacts on the iGPU), I guess we should hope that it is only the BIOS for your system, and not for all D840MB boards. So personally, I would go with the narrowest possible match (which this patch currently does). But, I would not be surprised if they actually managed to mess this up for all boards. But until someone else reports the same problem, I guess we should give them the benefit of the doubt. Kind regards, Niklas
