post the original contents of the bios chip..
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

I have a strange behavior with unlocked 8440p.
Admin password removed succesfully, i can enter bios with F10 BUT i can't change any setting, whatever i do when i save, exit and enter again BIOS it's not stored, like it's locked on specific settings.
I tried factory defaults, secutiry reset, bios update through Windows but no success.
Seems like the admin password really gone but the permission to make changes in BIOS remained.
Attached is the unlocked file that i flashed.
What do i miss?

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 got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)... -

Hello to all of you! I need help with a BIOS file.
The BIOS chip is fried on my Asus F542UN laptop, and I bought a new chip that needs programming. I have a CH341a programmer but I need a .bin BIOS file. On Asus support page the firmware has another extension, .310 and from reading on this forum I understand that that file is not complete BIOS.
So, in short I need the "complete" BIOS .bin file to flash on the new chip. Another issue is that on back of the case the label says F542UN but on the sticker on the motherboard it's X542UN. -
Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer...
