American Megatrends Inc. (AMI) Firmware Update tool (AFU) is a versatile firmware update utility. It initiates firmware update requests that are processed by system firmware, therefore, robustness of the firmware update process, to a large degree, is defined by the properties of the underlying firmware. Coupled with a modern system firmware (a.k.a. BIOS), AFU delivers robust firmware update experience. Modern system firmware is a firmware that has up-to-date security improvements and is in compliance with the relevant industry specifications like UEFI and ACPI. While AFU still supports updating legacy BIOSes, AFU does not use the legacy update method for updating modern BIOSes but instead enforces firmware update security employing best practices defined by the UEFI specifications.
