I have installed on an Intel server motherboard S1200KPR Microsoft Hyper-V Server 2012 R2. The motherboard has 2 Intel network cards. A 82574L and a 82579LM network card.
None of the network card drivers which are available for the motherboard could be used for the installation. After a little search on the internet I found the following driver package for Windows Server 2012.
The driver package was successfully installed, but the driver package has only the drivers for the 82579LM network card installed. The second network card still has the standard Microsoft driver.
I tried to install the Network Card with powershell DeviceManagement cmd applet (Install Driver InfFilePath. "inf file>) from Microsoft but it does not work.
Can somebody tell me how I can install the missing drivers for the NIC 82574L? I
There aren't any drivers to download for the 82574L and Windows Server 2012 R2. See this thread for the explanation:
