Motherboard manufacturers ASUS and DFI are both working on BIOSes which will allow users to install quad-core Intel Penryn processors on motherboards equipped with an nForce 680i chipset - a feature which was labelled as being a major advantage of the new nForce 780i chipset. The enabling factor for these two companies is that they both use their own motherboard layouts, rather than NVIDIA's reference designs. Therefore, they have managed to create beta BIOSes capable of working with quad-core Penryn chips on 680i systems - the ASUS Striker Exteme and the DFI LanParty UT NF680i SLI-T2R. These BIOSes are not yet available to the public, but assuming there are no legal issues that would prevent them from doing so, it shouldn't be long before ASUS and DFI release them.
