Hi,

unfortunately my Lenovo ThinkCentre M93z AiO Machine Type 10AE did come without WiFi, so I tried to add WiFi6 with an Intel AX200NGW M.2 NGFF card via an M.2 NGFF to Mini PCI-E adapter, with the result that the machine stops booting with following error message:
Error 1802: Unauthorized network card is plugged in - Power off and remove the network card.

Any chance to remove the whitelist in the AMI-BIOS (FEKTA1AUS) of the machine???

Thanks so much!

After two days of testing (and sweating out of fear of bricking the PC), I finally succeeded.

The procedure isn’t very complex; it’s just a bit lengthy as you have to modify 20 bytes in the BIOS file, which are scattered across various parts.

The first thing to do is to find the exact model of your card, in my case an Intel® Wireless-N 7260 Single Band + Bluetooth, which I wanted to replace with an Intel® Wireless-AC 7260 Dual Band Universal 2.4G + 5G for 7260Ac + Bluetooth.

Although the card was listed as compatible with my M93Z, once replaced, I encountered the usual error:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

So I started searching and couldn’t find any solution, which led me to resolve the issue on my own.

For me, reading this post was enlightening, and I recommend it to everyone

[How-To] Whitelisting Your Wifi Card of Choice (in my case, done on an M93P Tiny)

First, you need to accurately identify your wireless card model using 'Device Manager'.

In my case:

PCI\VEN_8086&DEV_08B2&SUBSYS_42628086&REV_73

So, 8086 08B2.

In the BIOS, the card code is reversed, so you need to refer to the card as 8680 B208.

Next, you must find the exact model of the card to be installed, and for this, you need to insert the wireless card into a computer with an mPCI slot that allows booting.

In my case, the card to be inserted was:

PCI\VEN_8086&DEV_08B1&SUBSYS_40708086&REV_73

Which, when reversing the numbers, becomes 8680 B108.

Now you need to download the latest available firmware version, which is FEKTA2A

Lenovo M93z bios download page

Then, run the downloaded file (fejya2usa.exe), allowing the archive to be extracted but not starting the update.

Inside the directory:

C:\SWTOOLS\FLASH\FEJYA2USA

you’ll find the BIOS file IMAGEFE.ROM.

At this point, download and launch UEFITool (mandatory version 0.21.5) to edit the BIOS image (UEFITool_NE_A68_win64.zip or UEFITool_NE_A68_win32.zip)

Press CTRL + O together and load IMAGEFE.ROM.

Then press CTRL + F and search for your card model (in my case 8680B208 without the space).

In my case, I found 20 occurrences.

Then, choose the first occurrence from the lower part of the window, double-click on it, and in the upper section, the exact location where the occurrence was found in the 

PE32 image section 

will be highlighted.

Right-click on it and select Extract body... and save it somewhere.

At this point, open the Hex Editor page and load the file you previously saved by clicking on OPEN FILE.

Once the file is loaded, go to SEARCH and insert 8680B208 (this applied to my card) leaving only the boxes Hexadecimal Value and Little endian checked, and click on find next.

Once found, modify the 4 bytes with the model of your card (in my case 80 86 08 B1).

Press Export and save the file.

Now, go back to UEFItool and right-click on the highlighted part,

PE32 image section

and choose Replace body and load the file you modified.

Repeat the process for all 20 occurrences.

Once finished, press CTRL + S and save the new IMAGEFE.ROM.

Now, you need to find an older version of afuwingui to flash the BIOS because the one extracted in the FEJYA2USA directory gives an error.

I found version 1.08, which I downloaded from here

Once the file is extracted, launch afuwingui and load the modified IMAGEFE.ROM file.

Check the boxes BOOT BLOCK, NVRAM, and PRESERVE SETUP (and select ALL in the box just below), then start the BIOS update.

After the procedure is completed, the computer will restart. Once it restarts, turn it off again and insert the new network card, and you're done.
