Not to be confused with AMIBIOS 07.00.10, which is based on a different codebase.
AMIBIOS 07.00.xx is a family of AMIBIOS versions developed by American Megatrends from 1999 to 2001. These releases are assumed to be public pre-release versions of what would later become AMIBIOS 8 due to a lot of similarities between both versions.
This release brought many new features over AMIBIOS 6, such as new 640x480 resolution POST and setup screens with an 8x19 font (although not on all instances), a completely different POST screen style, bitmap logo support in POST (for 640x480 resolution POST screen only), up to 2 TB hard drive support, code bug fixes and improvements. AMIBIOS 07.00.xx also retired the fixed core release dates used in the identification strings of most older AMIBIOS versions. With AMIBIOS 07.00.xx the string date is the compile date of the BIOS instead.
AMIBIOS 07.00.xx was not commonly used (except for mostly some Intel i8xx and ServerWorks chipset motherboards) and in 2001 it was replaced by AMIBIOS 8, which is assumed to be the final release of the 07.00.xx family versions.
Setup Utility
AMIBIOS 07.00.xx has only one known setup utility, Easy Setup. Although the instance of Easy Setup on 07.00.xx (and AMIBIOS 8) is different from the instances found on AMIBIOS 6 and 07.00.10. So far, no instance of AMIBIOS 07.00.xx with Simple Setup (AwardBIOS-like setup utility) are known, even though AMIBIOS 8 does have Simple Setup. Although Simple Setup still may have existed for 07.00.xx.
Unlike the Easy Setup of AMIBIOS 8, the gradient bar at the top does not move and is a still gradient. The moving gradient was available with some versions of AMIBIOS 8 only.
Modification tools
AMIBIOS 07.00.xx is the earliest version of AMIBIOS to be supported by 32-bit Windows compatible versions of AMI's BIOS modification tools. AMIBCP 2.25 Beta is known for being able to open and modify 07.00.xx ROM files, although newer versions of AMIBCP might fail to do so.
AMIBIOS 07.00.10

Despite the version number 7, AMIBIOS 7 (07.00.10) is believed to be based on the older code base used by AMIBIOS 6 (rather than the new codebase of 07.00.xx), due to it sharing more similarities with AMIBIOS 6 rather than with AMIBIOS 8. Therefore it is not to be confused with 07.00.xx.
Although it is uncertain why this version was called AMIBIOS 7 (or "07.00.10"), it might have been because AMI wanted to release a stopgap BIOS version based on the older AMIBIOS 6 codebase while 07.00.xx was still in development, and they could have wanted to market it as a new version. Therefore, 07.00.xx could have been renamed to AMIBIOS 8 during its late development. However, this can't be confirmed and is only a theory. Although 07.00.xx and 8 are very similar, they still have some slight differences.
