              HELLO friends, seeing that many had problems and I tried the bios here and they all had the same problem,
              which is 30 seconds to turn on, or the laptop does not turn off or does not suspend it stays with a black screen,
              that happened to me with the bios, the problem with the laptop that I have is that a person erased the chip completely
              and did not leave a backup of the original, so after 2 days of testing and testing I found the solution, I leave here the copy
              of the bios that I managed to create, these bios are completely blank, you will have to manually enter all the information
              of the ID, serial, etc. The equipment is currently giving an image 2-6 seconds after turning on, I tell you that I used the P91 build
              since the P85 gives the problem that it takes a long time to give an image, it does not turn off, or it does not turn on, or the fan stays on full blast,
              as I see or understood when checking the P91 is for Vpro processors although the label of this equipment does not indicate that it is Vpro, so I recommend that you try the P91 first

                      It doesn't work, I'll tell you.
                      If I use the P85 BIOS, the computer turns on, but it takes more than 30 seconds to load the image. After that, the Wi-Fi and everything works. The Wi-Fi button also works, but when I turn it off, the computer doesn't turn off. It stays on a black screen with the LEDs on.

                      If I use the P91 BIOS, it turns on and off perfectly, and the image loads within 5 seconds of turning on.
                      But the Wi-Fi button doesn't work.
                      When I enter both BIOSes, I realized that the Wi-Fi enable option isn't available on the P91.
                      And is there a solution for this on the P85?

                            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,...
