is an official, though primarily restricted, utility developed by American Megatrends Inc. designed for the modification of UEFI BIOS files. Specifically, version 4.50.0.23 is considered the most stable and recommended version for AMI Aptio IV BIOSes.
Serious errors can result in a non-booting system. Key rules include never flashing a BIOS you haven't tested; using a programmer to reflash the original image; and always creating a verified backup of the original BIOS before any modifications.
Used to patch or update CPU microcode to support newer processors or fix security vulnerabilities.
