A post was merged into an existing topic: [OFFER] Asus Q87M-E- v3801 BIOS with added NVMe Support
Asus WS C422 Pro/SE mainboard gives “10 - Error: Unable to load driver.” under Windows 11 with AFUWIN64 tool v3.05.04.
Any suggestions? please help!
or
Thanks for your help, unfortunately I have moved to Antalya/Manavgat for the summer. When I will return to Ankara I will try! 
Under Windows 11, AFUWINGUI.exe v3.05.04 does not work at all. 
Can it may run at Windows 10?
I have tried with AFUWINGUI v5.13.00.05, it run, but error message!
Stage :
Failed!
Address:
0xFFFFFFFF
Note:
AFUWIN_3.05.04 works on my Windows 10 notebook.
For AMI APTIO IV bioses not modern V.
For AMI APTIO V Bioses not IV
Both versions run on Wind 1x
I have tried with Aptio V AFUWINGUI v5.13.00.05, those error messages appeared. Both for moded and original bios. Thus Aptio V bios variant does not work for C422 variant maybe.
AMI tools are only referred in this guide due to the fact, that the last 3.05 version still accepted the /GAN cmd and let flashing mod bios (Modified Bios files), no other upper versions would succeed in this switch, this version was only viable for old bios types from AMI, Aptio IV core, understood now?
I dont care about any chipset here, this motherboard uses Aptio V Core bios, so the old flash 3.05 /GAN wont work and the latest AMI tools DO NOT ALLOW flashing mod files, understood now?
The board features USB BFB feature…did you read the damm guide about this feature, clearly not, for sure or you wouldn’t still be here doing stupid tryouts with official modern AMI tools and expecting to flash modified bios files on a motherboard.
Over_n_OUT of here.
I have Asrock x570 Phantom Gaming 4 and it has intel ethernet on board so if i remember correctly the serial number must be written to modded BIOS right? If this is true where can I find a guide how to do this? Im going to use flashrom to flash modified bios.
@euranoooo
Welcome to the Win-Raid Forum!
Which Serial number do you mean? i have an ASRock x570 mainboard with an on-board Intel Ethernet Controller as well, but never had a problem with any Serial number after having flashed a modded BIOS.
Nevermind probably i missunderstand something. So should I just download bios from manufacturuer, add ffs module I want, remove all AmdSpiRomProtectDxe modules and flash it using flashrom is that correct? Or removing protection modules is not necessary?
@euranoooo
According to my recent tests the Flashrom v1.2 Utilities may not work with the latest ASRock X570 Series mainboard BIOSes.
What about using external programmer? Can the modified bios program into chip like that? Why still people not managed to find a good solution here?
I have managed to find a related topic at: UEFIPatch: BIOS patches for C422, C621/C622, X299 based motherboards - vanilla (unpatched) kernel & native power management - UEFI | InsanelyMac
But the “patches.txt” (https://www.insanelymac.com/applications/core/interface/file/attachment.php?id=344875) can be downloaded after log in. [Look to the latest note at the bottom!]
“./UEFIPatch <ROM/CAP/Bios Image file for your motherboard> -o <patched bios file name, can be whatever you want>” can it work? I have no idea…
Lets start by downloading from “Release 0.28.0 · LongSoft/UEFITool · GitHub” [UEFIPatch_0.28.0_win32UEFIPatch.exe.zip] UEFIPatch_0.28.0_win32.zip file. It has 3 files in it.
UEFIPatch.exe
patches-misc.txt
patches.txt → This file will be replaced!
Finally the command input: ./UEFIPatch <ROM/CAP/Bios Image file for your motherboard> -o <patched bios file name, can be whatever you want>
--------------------------------- oooooooooooooooo --------------------------
BUT, I am not sure about, the patch file is only related with Hackintosh or not!
Then are the original UEFIPatch_0.28.0_win32.zip contents are enough for flashing the bios that we are looking for or not! Any ideas?
Latest note: According to this post: https://www.tonymacx86.com/threads/new-uefipatch-patches-unlock-0xe2-0x1aa-boot-catalina-without-any-kernel-patches-native-power-mgmt-on-c422-c620-and-some-x299-motherboards.293629/
Patches.txt is downloadable from there, but it is related with Macs only!
Without the Patches.txt the UEFIPatch command makes modifications to the second file. I have tried the result, but Asus bios tool said: It is not a proper bios!
Fernando,
This seems a way of flashing new mainboards. Lets ask others their ideas!

After having read your edited post I understand what you want to get investigated.
As soon as I have gotten several reports about successful flashes of modified BIOSes by using the tool UEFIPatch the start post will be updated (by me or by my successor). What we need are valuable results and not speculations.
“… you want to get investigated.” ?
I don’t want to be investigated. I want to be sure about the new flashing procedure. I can not ask new questions related with the topic at those forums, thread is closed for new replies.
If you quote a text just partly, it should not be meaning-distorting.
How often did you test “the new flashing procedure” and where are the results?
I know but my BIOS (3.20) doesnt have AGESA 1.2.0.0 yet so i believe i can do it safely?
Probably yes. Either it works or not, but your currently in-use will not get corrupted. Don’t forget to save an SPI Backup before trying to flash the modded BIOS.
