Hello,
I am going to assume that this is not for production from the motherboard.
Have you tried using the Intel tool to install drivers? if you go to https://downloadcenter.intel.com/ and click get started.
What you will need to do is use a USB adapter to get you connected to the internet first as this tool will scan your system and then download any Intel drivers that are missing or need updating. USB network adapters can be bought cheaply if you do not have one already.
I hope this helps. If you need any more help let me know.
Thanks
Richard
