        I exported a clean bios from update file via pfs extract.

        1. Build clean bios with clean ME, PMC, PCH in flash image tool.
        Result: Dead

        2. Build clean bios with no changes in ME, new PMC, PCH
        Result: Dead

        3. Build old bios with clean ME, new PMC, PCH
        Result: The same

          1st boot, press F2, write service tag, disable Absolute, save, restart.
          2nd boot press Alt+F to exit manufacturing mode.
          Good luck.

                [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,...

                Dell 9010 MT BIOS Update Always Fails
                by mikeybass
                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...

                Dell Latitude 5400 Chromebook UEFI bios
                by jhanra
                Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...
