[4] It is headquartered in Building 800 at 3095 Satellite Boulevard in unincorporated Gwinnett County, Georgia, United States, near the city of Duluth, and in the Atlanta metropolitan area.

[6] As hardware activity moved progressively to Taiwan-based ODMs,[7] AMI continued to develop BIOS firmware for major motherboard manufacturers.

[3] Its product line includes or has previously included AMIBIOS[10] (a BIOS), Aptio (a successor to AMIBIOS8 based on the UEFI standard), diagnostic software, AMI EC (embedded controller firmware), MG-Series SGPIO backplane controllers (for SATA, SAS and NVMe storage devices), driver/firmware development, and MegaRAC (BMC firmware).

[3][4] American Megatrends Inc. (AMI) was founded in 1985 by Subramonian Shankar and Pat Sarma with funds from a previous consulting venture, Access Methods Inc.

After Access Methods successfully launched the AMIBIOS, there were legal issues among the owners of the company, resulting in Sarma buying out his partners.

Later versions of AMIDiag support UEFI, which allows diagnostics to be performed directly on the hardware components, without having to use operating system drivers or facilities.

[10] AMI does not sell to end users, and itself produces no end-user documentation or technical support for its BIOS firmware, leaving that to licensees.

[18] This ID string comprises various pieces of information about the firmware, including when it was compiled, what configuration options were selected, the OEM license code, and the targeted chipset and motherboard.

[17][20][21] The StorTrends family of network-based backup and storage management software and hardware includes several NAS and iSCSI-based SAN servers with 4, 12, or 16 drive bays.

StorTrends iTX 2.8 is designed to support Storage Bridge Bay specification that provide Auto-Failover capability to ensure that any interruption is handled without affecting data.

On March 7, 2018, American Megatrends officially announced that it ceased development of DuOS-M.[26][30] No further updates were being released at this time, including bug fixes and security patches.

[31] The AMI WinBIOS was a 1994 update to AMIBIOS, with a GUI setup screen that mimicked the appearance of Windows 3.1 and supported mouse navigation, unusual at the time.

WinBIOS was viewed favorably by Anand Lal Shimpi at AnandTech,[32] but described by Thomas Pabst at Tom's Hardware as a "big disappointment", in part because of problems with distributing IRQ signals to every PCI and ISA expansion slot.

[33] In July 2008 Linux developers discovered issues with ACPI tables on certain AMIBIOS BIOSes supplied by Foxconn, ASUS, and MSI.
