    MSI Z77a G43 BIOS request

    Hi all, I'm having a nightmare trying to flash the original BIOS to the MOBO MSI Z77a G43. It seems I need a .ROM format. If anyone has a copy, I would be very grateful.

    I am trying to flash the BIOS using the CH341 programmer software using Neo Programmer and ASProgrammer, with no luck; it keeps saying the size is wrong.
    chip is W25Q64FV [3.3V]

    Regards.

      Just extract and rename E7758IMS.2D0 to .bin, it's already 8388608 bytes
      Select the correct BIOS chip model first

          I'm using the files from the MSI website. But it doesn't seem to be working.

          What do you mean Select the correct BIOS chip model first. And which software do you suggest I use. Asprogrammer or Neo Programmer. Or another software?

          Thank you for your reply.

              IC - Search, type W25Q64FV, check the picture below
              Click image for larger version Name: asprogrammer.png Views: 0 Size: 35.4 KB ID: 3757697

              Either AsProgrammer or NeoProgrammer is fine, both support W25Q64FV

                  The right BIOS Programmer - The right software (HP Elitebook 820 G1, 840 G2) no soldering, EC, DMI, ME
                  by STKR123
                  Greetings badcaps community,

                  I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
                  So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

                  Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

                  I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

                  These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

                  I learned that desoldering...

                  🛠️ 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
                  ...

                  Bios Request HP 17-CN0023DX
                  by David Gee
                  Hello,

                  I am currently working on recovering my HP Laptop (Model: 17-cn0023dx) after a BIOS corruption issue. The laptop is stuck in a no-boot state, and the Caps Lock light is blinking with a 3.2 code (3 long, 2 short), which according to HP documentation indicates a BIOS corruption failure.

                  I have prepared a USB stick using the HP Cloud Recovery Tool, but I confirmed that it does not include a BIOS recovery image for Crisis Recovery. I also attempted to extract the BIOS file from the spXXXXX BIOS update package provided on the HP Support site, but that update only provides...
