Number of employees 1000+ worldwide Website American Megatrends Incorporated ( AMI) is an American and company, specializing in hardware. The company was founded in 1985. Shankar was appointed chairman and president in 2011. It is headquartered in Building 200 at 5555 Oakbrook Parkway in,,, near the city of, and in the. The company started as a manufacturer of complete, positioning itself in the high-end segment.

Its first customer was PCs Ltd, later known as Computers, making one of the first designs. As hardware activity moved progressively to -based, AMI continued to develop BIOS firmware for major motherboard manufacturers. The company produced BIOS software for motherboards (1986), server motherboards (1992), storage (1995) and remote-management cards (1998). In 1993 AMI produced MegaRAID, a storage which major (including HP and Dell) adopted. AMI sold its RAID-division assets to in 2001.

As of 2011 AMI continued to focus on OEM business and technology. Its product line includes AMIBIOS (a ), Aptio (a successor to AMIBIOS8 based on the standard), diagnostic software, remote-access firmware, motherboards, backplane controllers, driver/firmware development, service processors, iNAS and SAN storage systems for, and 'solutions' for the operating system.

A chip containing an old version AMIBIOS image, pulled from an ECS motherboard American Megatrends has a strict OEM business model for AMIBIOS: it sells source code to motherboard manufacturers or customizes AMIBIOS for each OEM individually, whichever business model they require. 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. However, the company published two books on its BIOS in 1993 and 1994, (listed in ), written by its engineers. During powerup, the BIOS firmware displays an ID string in the lower-left-hand corner of the screen. 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.

The original AMI BIOS did not encrypt the machine startup password, which it stored in non-volatile RAM. Therefore, any utility capable of reading a PC's NVRAM was able to read and to alter the password.
