I am having a real struggle, unsure why, I am usually pretty handy at this.

I bought a Minisforum UM690 PC, which I want Server 2019 Hyper-V Core on. (HomeLAB)

Installed Hyper-V OK, but says no NIC. 

Tracked down the hardware ID's under the terms "Ethernet" and "Network" to:

PCI\VEN_8086&DEV_125C&SUBSYS_00008086&REV_04\5847CAFFFF7388DD00
    Name: Ethernet Controller

PCI\VEN_14C3&DEV_7961&SUBSYS_796114C3&REV_00\4&1F328C3&0&0012
    Name: Network Controller

I downloaded intels drivers (which actually state they work with 2019 but don't seem to)  

https://www.intel.com/content/www/us/en/download/19372/intel-network-adapter-driver-for-windows-server-2019.html

Extracted it out, found the e2f.* files in Wired_driver_29.0_x64\PRO2500\Winx64\NDIS68 (Readme states The driver package supports devices based on the following controllers:
  * Intel(R) Ethernet Controller I225)

Got as far as opening the e2f.inf file, and now I am stuck. I understand in theory how to do this, but for some reason, today, I can't make this work in my brain. 

This exists in In Section :

[Intel.NTamd64.10.0.1..17763]

%E125CNC.DeviceDesc%      = E125C.10.0.1..17763,        PCI\VEN_8086&DEV_125C

But doesn't in Section: 

[Intel.NTamd64.10.0...17763]

Do I just copy %E125CNC.DeviceDesc%      = E125C.10.0.1..17763,        PCI\VEN_8086&DEV_125C into Section [Intel.NTamd64.10.0...17763] save, and run pnputil.exe /i /a e2f.inf?

In ELI5, is someone able to tell me what exactly gets pasted where exactly please?
