AMI Flasher is a utility program that helps you to update your BIOS - the code that runs the first moment you boot your PC. It was created by AMI to support flashing AMI BIOS based data files.

The BIOS code is stored on the motherboards on Flash chips since its introduction in 1993.

Over the years AMI has released DOS, Windows and Linux based flashers for different versions of AMI BIOS and AMI UEFI BIOS.

The DOS based versions can't be run from Windows or other operating systems. You'll need to create a bootable DOS disk.

Please read our How to flash your bios FAQ to correctly use the AMI Flashers.
