    Dell Latitude 5520 - dump bios to obtain password

    Hello,

    I am not experienced in electronics, but I really want to check if my idea is possible.

    I have motherboard replaced from Dell Latitude 5520 (11th gen on i5 CPU).
    BIOS/UEFI access on that MB/PC is blocked by password which I want to get it know - even if I need some bruteforcing or stupid manual activities.
    There was no computrace activated.

    I was happy when I saw many posts about removing BIOS password based on .bin file dummps. I wanted to go little further - get to know the password from the dump.

    1. I do not know how thebios chip is identified and I would ask you if my assumption is good or wrong:

    U2502 on PCB >> 8-pin winbond chip 25r256jven 2105 6103 moo14 marked on photos.

    I have created some photos if needed. So the back side of the MB is also attached. If you need more picz please let me know.

        Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
        by Ahari
        Hi all,

        This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

        I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

        I...

        by Citymin
        Hi all,

        My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
        The charging red LED lights up, but the charging screen doesn't show any indication.
        When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
        (I've tried removing the battery and resetting the device, but the issue persists.)

        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...
