I have a Dell 3630 tower. I am told it has Chipset C246. DELL cannot provide me with Chipset drivers or driver for UHD630 Graphics for OS Windows 8.1. Can anyone help?

That is because only Windows 10 is supported on 7th gen and later processors. There are no drivers for anything less than windows 10.

Now, the chipset INF is not a driver. It is a definition file for the devices supported on your motherboard.

And, this forum is for Intel Desktop Boards, which you do not have.

Lastly, you want to use Windows 8.1? Why?
