Has anyone attempted to install Windows Server 2012 R2 or other version on the 5i5RYH? The OS installs however the Ethernet controller and LAN controller won't take any drivers. I attempted the driver kit for the 5i5RYH and the one for the 5i5MYHE. There are also a couple of unknown devices but I suspect those are the IR and Bluetooth, which I don't really care about.
I now 2012 R2 isn't a supported OS, but why wouldn't it be? I installed Windows 8.1 Enterprise on it and am able to run the Client Hyper-V as well, Would prefer to run Server Hyper-V instead.
