Flash the BIOS

  • Flash the BIOS, see how below.
  • Reboot and go into BIOS settings.
  • Restore BIOS defaults.
  • Save changes and reboot.
  • Go into BIOS again if you want to adjust extra settings.

To flash the modded BIOS you have the following options:

  • Mi899 if you trust my app and don’t want to bother with console (command line) yourself.
  • FPT and AFU applications, see the syntax below.
  • External flash programmer if the BIOS is locked for software flash: [🇬🇧 CH341a – minimal usage guide how to read & write a motherboard BIOS](https://youtu.be/4qX2zihB6UE?si=vXVf4Fo430RfLJ05).

Extra notes:

  • The .rom and .bin file extensions do not matter as long as you have a binary BIOS file.
  • Make sure to buy a programmer with a voltage switch, like this one: CH341A Programmer V1.7 1.8V - 5.0V.

FPT syntax

To save / dump the current BIOS execute the following:

fptw64.exe -d bios-file-name.bin

To flash BIOS from a file execute the following:

fptw64.exe -f bios-file-name.bin

Make sure to run console (CMD) as administrator and replace bios-file-name.bin with the actual file name.

AFU syntax

To save / dump the current BIOS execute the following:

Important: AFU saves only half of the BIOS (8MB) instead of the full BIOS (16MB). Such dump can be flashed with AFU, but not with FPT.

AFUWINx64.exe bios-file-name.bin /O

To flash BIOS from a file execute the following:

AFUWINx64.exe bios-file-name.bin /P /B /N /X

The UEFI system does not boot after TBU

This is a known UEFI bug of the LGA 2011-3 X99 platform. The fix is simple:

  1. Shut down the computer.
  2. Disconnect the power cord.
  3. Disconnect all storage devices.
  4. Turn on the computer.
  5. Go to the BIOS and restore defaults.
  6. Save changes and restart.
  7. Go to the BIOS and apply any extra settings you wish, such as RAM timings. This is an optional step.
  8. Turn off the computer and disconnect the power cord.
  9. Connect all storage devices back.
  10. Turn on the computer, it should work properly.
