First off, the big question is how are you trying to run it. DOS window, reboot to DOS, or a 3rd-party DOS emulator (DOSbox, etc)?
You can't use a regular DOS window, as Windows uses its native memory scheme, which is incompatable with Armada's requirements. If using an emulator or rebooting to DOS, pasting in copies of the contents of the configuration files (either emulator's or DOS's config.sys and autoexec.bat, depending on how you're trying to run it) would probably get things started.
