Re: bios password dell latutide 3540
Have you tried the password at bios-pw.org .The bios password is stored in the KB9012 EC on this model. https://cdn.badcaps-static.com/pdfs/...928fc3eda7.pdf -

Re: bios password dell latutide 3540
The e7740 you linked to had a very old bios version A14, so the EC would be an older version as well. Version A17 bios changed the password algorithm , and the latest bios has a new master password lockout, idon`t know if a bios downgrade would work if the latest bios and EC was flashed ?Comment

Re: bios password dell latutide 3540
Dear Rioreno, anybody can be wrong-no fighting for that. If my memory is not failing, then e3540 password goes to kbc. Yeh, agreed it dependes on platform to platform. Its not universal that password will be stored in kbc but as far as i remember, latitude e3540 pass stored in kbc.
Let nabiglo flash the bios first so that confusion goes away.Comment

Re: bios password dell latutide 3540
I am sure we are in the same spirit, spirit to help ...
I still have to learn a lot.
I say from my quote, "better nice to try" there's nothing wrong with trying to make sure. Whatever the results from Nabilgo, there will be lessons learned later,especially by me...Comment

Re: bios password dell latutide 3540
Forgive me, it seems that there is little missing from what I have done.
Will you try 1x again ... if it fails then I give up ...
The NVRAM module I extracted turned out to have to change the header layout first ...

You did changed the kbc from another board but did you programmed it?? I dont think it will work without flashing even if we forget about password.

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,... -

Hello I have a dell optiplex SFF plus 7020 with a password that I recovered from e-waste. It is possible to get the password removed via the bios patch method? I managed to dump the 32MB bios chips and would like help patching it to MFG mode so I can clear the password.
Thanks.

Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...04-23-2025, 04:30 PM
