    Compare two BIOS, and correct missing DMI ?

    Hello to all!

    I have a question.

    When you , find here online a dump of a BIOS that is working just fine but has missing information .
    But you , have the "original faulty " bios with all the information on it, how do you transfer the details on the "working"bios and reprogram it ?

    I mean ,without the usual HP tool , that you press everysingle word , i mean about the "general bios" editor.

      It depends.If its an insyde bios then the DMI (serial number etc) is usually in 1 big block,and the win key,if there is one ,is in a different place.Its a matter of finding them, then copying using a hex editor from the old to the new.

          It's from a 330S-15ARR Lenovo , with Ryzen 2500U ,i have the original file (read and verified) but i am using the HxD editor, and cannot find "anything" particular from the Serials, Model ,etc.

              This post in the 330S-15ARR bios request thread should help you , @peste has given the offsets to enter in your hex editor https://www.badcaps.net/forum/showpo...9&postcount=29

                  in newer versions of bios (uefi) most of DMI data is compressed. individual modules can be extracted / replaced with UEFITool (not all versions support replacing modules, you will have to do some research)

                          ASUS TP500LA BIOS request/repair/merge?
                          by jbonavita
                          Hi, my laptop wont boot at all
                          With original bios no POST, only LED lights
                          With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                          Some issues
                          A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                          B- If updated from 500LN version 203 to 300, the battery stops being recognized

                          Things I tried

                          1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                          by zenius
                          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                          by Wahaz
                          Hello,

                          I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                          So I thought it was a Bios problem.
                          I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

                          Flashing ASUS UX51VZ with correct bios
                          by Flyview
                          Hi!

                          Happy to be part of this forum for my first post!

                          Short story:
                          I believe my dad's UX51VZ has an incorrect bios (v207) for a UX51VZH flashed onto it. I'm not quite sure what the differences are between UX51VZ, UX51VZA, and UX51VZH. The serial number of this machine is D5N0CY845932229 and comes up as a "UX51VZ-DB103P" when checked on this ASUS website. All of the bioses can be found at this ASUS website.

                          1) Do I have the correct bios or should it be the v205 for UX51VZ? Is there something I can check inside the machine to make sure?
                          ...

                          [HELP] G712LWS BIOS capsule
                          by TraJikar Mac
                          I need someone that can capsulate one of the bios files below, and i prefer the older bios version so i can flash it using CH341A tool into the bios chip.
                          The manufacturer BIOS files are bigger than the BIOSbackup1.bin files by 256KB and I don't know how to fix or recompile it.

                          You can see in this link a conversation between me and other people (Starting at page 10) who tried to help me (thanks to their efforts), but i still couldn't fix it and the laptop is considered as dead until now.

                          Also, I uploaded a backup file for the bios that I extracted by using CH341A...
