OpenNT 4.5
This is Stephano's OpenNT build sr687 the latest (and only) version I could find. I tweeked some stuff to allow me to get it to build... Although you have to run the build process twice, but I was able to generate an ISO and boot it up. This is not for the weak, it's crazy involved to set this up, but I did what I could. To get the 7z file run: copy /b "OpenNT45(Source).z00" + "OpenNT45(Source).z01" + "OpenNT45(Source).z02" "OpenNT45(Source).7z"

Extract and run "innerspace.bat" News: Sound has been installed to work with DoSBox!
