Default HOWTO: Flash older BIOS on ASUS Z170

WARNING: This may cause your system not to start. Use at your own risk.

The below procedure allows you to flash an older BIOS on motherboards without USB BIOS Flashback feature. The lack of this feature means there's no simple way to recover if things go wrong.

Software required
  • UEFITool v0.21.5 Thread Mega
  • Intel Flash Programming Tool for ME 11.0 Hwbot (note that you need to unzip using a software which supports RAR5)

Prepare the BIOS file for use with FPT
  1. Get the BIOS for your motherboard in CAP format (in this case MAXIMUS-VIII-IMPACT-ASUS-0019.CAP)
  2. Open the CAP file in UEFITool



  3. Export to ROM (MAXIMUS-VIII-IMPACT-ASUS-0019.ROM)




Using FPT to flash the BIOS on your system
  1. Open a command prompt with Administrator rights and navigate to your FPT directory
  2. Flash the BIOS by using the command fpt -bios -f BIOS_FILE.ROM


Note: There are DOS/EFI/Win32/Win64 versions, this guide uses the Win64 version.

I can overclock my COre i7-6400 T (ES) on H110\B150 ASUS motherboard, (e.g. ASUS B150 PRO GAMING with 10 phases)?

I get the same error, the ftp command doesn't exist. I copied the files onto the same folder that my .rom files are located and I still get the message.
