AMD's Smart Access Memory feature turns out to be pretty much just a very well optimized use of an already existing, but normally un-exposed feature on PCIe. Nvidia is currently working on a driver to support this feature for Nvidia GPUs, but will require it enabled on the motherboard it's installed on.
As it stands right now, we're looking at only the latest Intel chipset getting this feature exposed by motherboard makers in bios updates, Asus is already ahead of the game and has a beta bios with support ready before Nvidia even has a driver ready to go. This means it's a simple switch to throw to expose the feature in bios, most likely. The speed which Asus was able to drop a bios of this sort really strongly hints at the ease of exposing the feature.
This leads me to wonder... those of us out there with 200 or 300 series chipsets also have full hardware support for this feature, but nobody will be releasing any bios updates to expose the feature. But if my theory is right, this should be something that can be modded into a bios manually?
Of all the places in my entire 30 years in the IT industry, I know this forum is the place to ask this question. Does this sound like something that might be possible? It sounds, in theory at least, like a pretty simple hack of a bios file, probably just flipping a flag from 0 to 1 to expose the feature? I don't know, just guessing out of my depth here, but it seems possible?
