AFUDOS is a command-line utility created by American Megatrends Inc. (AMI). It allows users to flash, backup, and update the BIOS on motherboards utilizing AMI firmware. The software runs strictly in a DOS environment, bypassing the stability risks associated with updating a BIOS from inside a Windows operating system.
