    macbook air A1466 820-00165-a bios

    Hi all,
    I am working on a Apple MacBook Air A1466 820-00165-A logic board. The BIOS got corrupted or shorted because I have fan spin and all voltages are there, no chime or boot.
    The BIOS probably needs ME cleanup and serial change to FVFYQ6F2J1WK. Please help

    and attached version number and corrupted BIN file

      Just cleared ME for you and the serial number is same as per your request, but I think that this will not solve your problem, I think that the bios itself is corrupted, not the ME region, but here you go, try and post results.

      I don't provide help for people using CH341A and a clip.

                      Surface Pro X 1876 Bios corrupted
                      by FalconPunch
                      Hello everyone, I happen to have a Microsoft Surface Pro X 1876 in my hands. It was brought to me by a friends which happen to have taken off the bios chip to test another motherboard. Upon putting back the bios chip on the original motherboard, The PC is stucked on Windows logo and won t boot to bios or anything. I suspect that the changes of bios chip somehow corrupted the firmware inside. Is the hypothesis correct?

                      Also i extracted the bios inside the chip which was on Winbond 25R128JWPQ you can find the file attached if you can fix it (if possible, I would like some insight on...

                      🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
                      by macabook
                      Hello everyone,

                      I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
                      🧩 Initial Issue
                      • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
                      • External display (HDMI) shows
                      ...

                      Lenovo TD350 ThinkServer BIOS v505 Corrupted BIOS,
                      by TylerHyde21
                      Hello, the bios on my Lenovo TD350 ThinkServer got corrupted during a bios update, the bios restore function killed the Server.
                      I need to flash the bios inside the MX25L12835F SOP8, i have already desolder the chip and solder it into my SOP8 adapter and read it with a ROM programmer.
                      I use the innoextract 1.9 software to extract the bios file from the .exe file that i download from lenovo website, can you help me edit the Hex file (removing the Index part and resize the file)?
