AMIBIOS 8 is a version of AMIBIOS developed by American Megatrends in the early 2000s 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 (which AMIBIOS 8 is also based on) and the latter based on the older AMIBIOS 6 codebase.
Although it was released in 2001, it was not widely used until 2003 with the release of the Intel 865x series of chipsets (codenamed "Springdale"). Despite this, it was a very popular BIOS solution at its peak and was used on many motherboards released between 2003 and 2011, making it a serious competitor to other solutions of that time, such as AwardBIOS v6.00PG. It was most commonly used on Intel chipset based ASUS motherboards released in that era, but was also used by many other manufacturers, including:
- ASRock
- Biostar
- Colorful
- ECS Elitegroup/PC Chips
- Foxconn
- GIGABYTE (mainly on some server motherboards)
- MSI (Micro-Star International)
- Supermicro
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.
