    You can replace the MAC in GbE (both at 0x1000 and 0x2000) with your own MAC from the sticker. There's a checksum in the GbE but afaik it doesn't need to be corrected for normal use.
    OK, i will change if necessary with nvm *.bin setmac or nvmac *.bin xx.xx.xx.xx.xx.xx and then even the checksum will be corrected.
    Thank you.
    Cheers!

      Are those nvm, nvmcheck nvmmac programs windows versions? Could you give me a hint what to search?
      I searched a while but could only find incompatible or older versions?

      Thanks in advance!

        No they are Linux programs. I use them on Ubuntu 20.

        You can find them here :
        https://notabug.org/osboot/nvmutil.git
        https://notabug.org/osboot/nvmutils.git
        and a little help here:

              Hy everyone,

              Is there a specific software to do a BIOS backup before trying to mess up with it?

              I would like to do some testing on the file

              thanks

                Hi!
                Read here : https://www.badcaps.net/forum/showthread.php?t=103526.
                There are several programmers and software for them.
                And as method u can use a clip for onboard programming or soldering iron or hot air for de-solder the BIOS chip, read it first (for backup) then erase and program the modified version.
                Cheers!

                  Re: Lenovo L460 LAN issue after BIOS dump flash

                  hello guys!

                  I dug for a long time and figured out bios thinkpad l460.
                  I have such a situation: the bios chip is out of order. Nothing from all the forums brought any results. after numerous searches, I assembled the uefi assembly to make it work.
                  1. the problem is the lack of startup at all (solution on the bios chip when flashing "status reg" qe=1)
                  2. I will not comment on intel ME, I found about 30 working versions of 11.x.xx.xxxx I think there are a lot more of them.
                  3.!!!! wired lan not work error: what I just didn't try in the available bios versions. solution: flash image tool v11 >>> network and connectivity>>>wired lan configuration>>>Gbe PCIe Port Select>>>Port5 to Port4. some may do the opposite.
                  please use the solution
                  gbe region contains only the address and model of the network card and its id.
                  4. encountered system friezes: freezes are short, barely noticeable. solution - me 11.8.83.3874
                  5. bonus found where the lenovo logo is hiding)))

                    PS5 EDM-031 1216A BIOS Issue
                    by Syph1979
                    Hi all. First post here, so I hope I'm getting this right and operating in the spirit of things here.

                    I've been working on consoles for a while now. Always learning and trying new repairs, but I have one that has been stumped and I wondered if anyone with more experience could help?

                    I picked up a PS5 from eBay recently. It was described as not having the disc drive, but it was also a no power unit. On testing it was clearly an issue with the supply (no 12v), so I replaced that and then when I inserted the power lead, I got 3 beeps. So far, seems all related. As I was...

                    MSI PRO B660M-G DDR4 - real bios dump from board needed (no stock bios)
                    by DynaxSC
                    Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).

                    I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...

                    🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
                    by macabook
                    Hello everyone,

                    I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
                    đź§© Initial Issue
                    • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
                    • External display (HDMI) shows
                    ...

                    K6604J Vivobook RTX 4070 BIOS Dump Request
                    by greelidd
                    Hi all! Tldr: need a bios dump (.bin format) for K6604J (rtx 4070 and i9-13980hx)

                    Longer story: my vivobook stopped booting after i switched out the thermal paste. I think the BIOS got corrupted. Everything i tried didn’t work until finally i decided to buy a CH341A BIOS programmer and just send over the BIOS directly from another PC onto the BIOS chip. I connected fine and backed up the existing BIOS, but i can’t find a clean BIOS that’s a .bin format. And I tried using UEFI software to extract all the files from the ASUS BIOS .exe file and get to the .bin but it was a .302...

                    Keyboard RGB issue - Dell g15 UEL 2 bios dump
                    by slade1
                    After a bios downgrade, the keyboard's RGB stopped working, now in the device manager the STM32 Bootloader device appears, I discovered that it is the rgb microcontroller, I believe that (STM32 bootloader) is because it does not identify the bios file (UEL2)

                    Does anyone have the BIOS dump (UEL 2) of the Dell G15? It is responsible for the RGB keyboard.
