So here I am again with another Freeware for you.
This is an AMI BIOS editor for BIOS Roms of the 386 era.
Yeah for AMI 64KB BIOS Roms dated up to 1993.

So this tool allows you to enable hidden options in the BIOS.
The official tool for this job is a very old version of AMIBCP.
Unfortunately this version is lost in history. Impossible to get!
Then we have the AMI Edit tool. This can do stuff, but not unhiding.
So my tool finally covers this gap in available BIOS editing tools.

Then for sure that is not all!
The tool also has the ability to Inject Option Roms into the BIOS.
Any Option Rom can be injected as long as it fits!
But for sure the obvious is to inject is my IDE-386+ Option Rom.
So yeah with all that, LBA28 disk support to any 386 AMI BIOS.
And yeah, super easy with just 10 clicks and a Rom programmer.
So forget ROM cards, and Network cards. No Hardware needed!
