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 the successor to both AMIBIOS 07.00.xx and 07.00.10, the former based on the newer AMIBIOS codebase (on which AMIBIOS 8 is also based) and the latter based on the older AMIBIOS 6 codebase. However, most OEMs did not start using it until the mid-2000s.
It was replaced in 2005 by Aptio, a UEFI firmware developed by the same company. However, it was still 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 the H55, H57 and Q57 for Intel processors and the AMD 970 with the SB950 southbridge for AMD processors (the latter only on the Maxsun MS-A970 Pro). Most systems based on Vortex86 SoCs, some of which were released after 2011, also use AMIBIOS 8.
