Is there any easy way to extract DMI info for HP BCU from old dumped bios when flashing new bios?
-
I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the commandit should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.Code:
"innoextract 7wcn38ww.exe"
The trouble I'm having is that I'm not getting the newly... -
Hello everyone,
I am still a beginner and want to learn more about flashing bios. First of all, thank you very much for the tutorials made on this forum it helps a lot.
Lets get straight to the point. When I try to flash the bios of my Lenovo X270 it restarts several times and always returns to the bios that was there at the beginning. When I get the bios from someone on the forum and write it to the bios chip, I always have the same serial numbers. I have the feeling that the pc is reflashing itself. Where could this come from? How to avoid this problem?

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,... -
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?

Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice...
