18.04.04 Server needs new eth0 driver for networking, help installing

Similar to the problems detailed in this thread,

I have a new-build file server with a Gigabyte Aorus AX Z490 motherboard.

I cannot get this machine to reliably raise network interfaces with eth0 and automatically gain connectivity on every reboot – at least without being physically present to do a hard reboot and inserting the ethernet cable into the back after the boot sequence has finished.

Could I have some handholding through this? I’ve never installed a linux driver manually before, and apparently the needed driver is not yet included in the 18.04 Server kernel by default. Oddly enough however, it was included when I first loaded 18.04 Desktop version on this machine to run trial tests. There were no connectivity problems under 18.04 Desktop (at least I think it was 18.04 Desktop, and not 20.04 Desktop).

In the posting linked at the top, that user listed out these steps:

I was able to solve this thanks to your workaround.

I had a different motherboard, so I downloaded the Windows LAN Driver
from Asus’s website at

I then downloaded the NVM Update Utility at
https://downloadcenter.intel.com/download/24769 since it has a Linux

The name of the file should be similar to FXVL_15F3_ASUS.bin, but the
ending will be different depending on the various Z490 motherboard
manufacturers. This can be found on the driver website for the
specific motherboard you are using.

After unzipping this file, I was left with two zip files,

I225V_Intel_Gigabit_Ethernet_Driver_V1.0.1.4_WIN10_64-bit.zip. I found
the FXVL_15F3_ASUS.bin in I225V_End_User_FW_UPDATE.zip and copy-pasted
this file over into the /700Series/Linux_x64/ directory for the NVM
Update Utility.

Next, we need to find the config file for the i225 driver. After
unzipping and searching the Asus LAN Driver files, I found the proper
config settings at config_i225.txt in I225V_End_User_FW_UPDATE.zip.
Again, the location of the config_i225.txt might vary depending on the
motherboard manufacturer’s LAN driver.

Lastly, I navigated to nvmupdate.cfg in /700Series/Linux_x64/, and
added this to the end of the file:

VENDOR: 8086
IMAGE DOWNGRADE: TRUE END DEVICE Once this is added, type sudo ./nvmupdate64e. After following the on-screen instructions, Ethernet
should connect immediately. Hope this helps anyone experiencing this

Somewhere in this process, I go completely off the rails and get lost. When I try sudo ./nvmupdate64e nothing happens, so whatever I’m doing wrong comes up prior to that point.

My lspci is as follows:

I need the 15f3 Intel ethernet driver for linux, and I have it (per that other thread’s postings) but I am too much in the n00b to novice (at best!) understanding with linux drivers to get any further. Anyone able to guide me along?
