Solution

Initialize the Ethernet Controller NVM using bootutil64e in Preboot.tar.gz at https://downloadcenter.intel.com/en/download/29137.

Things necessary

Process flow

  1. Turn off Secure Boot in the BIOS. (Required to execute step 4)
  2. Boot from Linux Live USB media
  3. Unzip Preboot.tar.gz
  4. Install the dedicated driver
  5. Run bootutil64e to restore the NVM to its default settings
  6. Turn off your PC
  7. Insert and remove Live USB media
  8. Turn Secure Boot back on
  9. Boot from Linux Live USB media
  10. Make sure it recognizes Ethernet

Remarks

1. Turn off Secure Boot in the BIOS

The procedure depends on the motherboard.

4. Install the dedicated driver

[email protected]:~$ cd APPS/BootUtil/Linux_x64/DRIVER
[email protected]:~/APPS/BootUtil/Linux_x64/DRIVER$ sudo ./install 
Extracting archive..OK!
Compiling the driver...OK!
Skipping removing QV driver - it does not exist...
Copying iqvlinux.ko driver file to /lib/modules directory...OK!
Driver installation verification...Installed!

If Secure Boot is not turned off

If Secure Boot is not turned off, the following error will occur.

[email protected]:~/APPS/BootUtil/Linux_x64/DRIVER$ sudo ./install 
Extracting archive..OK!
Compiling the driver...OK!
Skipping removing QV driver - it does not exist...

Driver installation verification...modprobe: ERROR: could not insert 'iqvlinux': Operation not permitted
rmmod: ERROR: Module iqvlinux is not currently loaded
Installed!

5. Run bootutil64e to restore the NVM to its default settings

Give bootutil64e execute permission

[email protected]:~/APPS/BootUtil/Linux_x64$ ls -l
total 3460
drwxr-xr-x 3 ubuntu ubuntu     140 Apr 18 13:05 DRIVER
-rw-r--r-- 1 ubuntu ubuntu 3541720 Nov 22 14:42 bootutil64e
[email protected]:~/APPS/BootUtil/Linux_x64$ chmod +x bootutil64e 
[email protected]:~/APPS/BootUtil/Linux_x64$ ls -l

6. Turn off your PC

Turn off the power of the PC once

7. Insert and remove Live USB media

If you do not insert and remove it, it will not be recognized the next time you start it, so insert and remove it.

8. Turn Secure Boot back on

Return Secure Boot to ʻON in the same way as in 1. Turn off Secure Boot in the BIOS.

9. Boot from Linux Live USB media

Boot from Live USB media in the same way as 2. Boot from Linux Live USB media

10. Make sure it recognizes Ethernet

[email protected]:~$ dmesg | grep e1000
[    0.809135] e1000e: Intel(R) PRO/1000 Network Driver - 3.2.6-k

Omission
[   21.479526] e1000e: eno1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx

You can see that it can be recognized by the ʻip a` command. You can also connect to the network.
