Revision as of 10:01, 18 December 2022
AMIBIOS 6 is a version of AMIBIOS made by American Megatrends and often known with the subcore date 071595 (July 15, 1995), although some few newer subcore dates such as 071599 (July 15, 1999) do exist. It was used for a very long time, from 1995 to around 2001 when it was replaced by AMIBIOS 07.00.10 (which then quickly got replaced by AMIBIOS 8).
Early versions (cores) of AMIBIOS 6 could still only detect up to 32 GB hard drives, however in around 1999 this limit was bumped up to 64 GB. It was also the first version of AMIBIOS to include built-in PnP (Plug and Play) support, an easy hardware detection technology used by Microsoft Windows 95 and newer versions.
POST screen
As AMIBIOS 6 was in use for a very long time, some changes to the POST screen (and the setup utilities and overall some features as well) have occurred. The EPA (Energy Star compliance logo, short for Environmental Protection Agency, used by AwardBIOS and enthusiasts) can also change depending on OEM/motherboard manufacturer and core version.

Setup Utility
Unlike AMI WinBIOS and AMIBIOS 5, AMIBIOS 6 included a variety of setup utilities for use by OEMs/manufacturers. Early versions only had AMI WinBIOS Setup Utility or Hi-Flex Setup Utility, while later Easy Setup Utility (resembling the Intel AMI Hi-Flex fork setup) and Simple Setup Utility (resembling the newer AwardBIOS setup) were also added.

Bugs and quirks
People have reported Plug and Play related issues on early AMIBIOS versions with it (assumed to be AMIBIOS 6). The issues are said to be fixed in around 1997, however.
AMIBIOS 6 also has a bug with it's CD-ROM boot option where it often can't boot into Windows XP ISOs. When attempted to, an NTLDR is missing error appears, regardless of used ISO.
Thomas Pabst of Tom's Hardware has also reported issues regarding IRQ routing with AMIBIOS 6 with WinBIOS Setup Utility, calling it "a big disappointment".
Intel fork

Intel forked AMIBIOS 6 subcore 071595 in around 1998 and began using it on their motherboards. This fork also used an unusual 063200 core number (last for regular AMIBIOS 6 was 063100). It was also later replaced with their AMIBIOS 8 fork in early-2000s.
