AMIBIOS 8 is a version of AMIBIOS developed by American Megatrends and released in October 2001. It was the last commercial version of AMIBIOS and it succeeded both AMIBIOS 07.00.xx and 07.00.10, former based on the newer AMIBIOS codebase (which AMIBIOS 8 was also based on) and latter based on the older AMIBIOS 6 codebase. Despite this, most OEMs did not begin using it until around the mid-2000s.
It was succeeded by Aptio, a UEFI firmware developed by the same company, in 2005. However, it still continued to be widely used on most systems until 2011, when it was discontinued for Intel's 6-series chipsets for LGA1155 motherboards. The last chipsets with AMIBIOS 8 were H55, H57 and Q57 for Intel and AMD 970 with the SB950 southbridge for AMD, latter seen on the Maxsun MS-A970 Pro motherboard only. Most systems based on Vortex86 SoCs, some of them released after 2011, also use AMIBIOS 8.
