      Maybe this gives you the correct binary: https://pcsupport.lenovo.com/ch/de/p...loads/ds038444 (open with 7zip and extract I0KT33A.bin)

      If you open it with UEFITool, you can see in the information box that this images is for 2 chips, my guess is "ME region" for the smaller EEPROM and BIOS region for the bigger one. It looks very similar to your two binary dumbs (if you concat them).

      You could extract the BIOS region by right clicking and selecting "Extrect as is...", but be aware, i'm just guessing here.. you can brick your system

        Thanks for help, but I'm afraid this too complicated for me.

        That's the problem.
        I don't have a serial number on a back panel (it's erased and in the bios too), just found this:
        Nachine type10110
        Configuration number 57310941
        MO: CS02120315
        CPU I3-3220
        HDD SATA 1Tb
        RAM 8G DDR3
        GPU Intel
        And on MB found that numbers:
        3000025600584
        10E2
        4619KA38L02

            I need a BIOS dump for the Samsung S49CG934SU monitor
            by Habble7
            The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

            Suspected Cause:
            I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

            Troubleshooting Attempts:

            Lenovo Tiny8 triple NVMe IQ6X0IL1 HQ670 NM-D581 Rev 0.5 M90q Gen 3 / P360 Tiny prototype board BIOS dump
            by Captaincrap420
            Hi, I hope this is the right place to post this. This is my first post on this forum.

            A friend helped me get a prototype Lenovo motherboard from China, it's got a hole drilled in it but I'm working on trying to revive it to some degree. I dumped the bios in hopes that it might be useful to someone, since this board is configured with the 3rd NVMe SSD slot and maybe it is useful as a reference for modding another bios to support this function. For example the M90q Gen 2 / P350's unpopulated 3rd NVMe slot footprint maybe.
            This bios dump is straight from the chip, nothing has been...

            Lenovo X1 Carbon 7th Gen Type 20R1 BIOS DUMP

            Board: GX490 NM-C661 Rev: 1.0

            I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.

            The problem with the laptop is that...

            Lenovo IdeaPad 330 15-AST 81D6 BIOS Recovery
            by jendkkd jeje
            So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

            I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...
