Pappy4u: I have many hunreds of maps from Duke Nukem that I use to play. Before buying the Atomic program here I used setup to load the maps. How can you play maps with the DOS Box??
I haven't got Duke 3D from here, but if the setup program is included, you can run it directly under DOSBox. You can also type the name of the map directly in the command line under the DOSBox prompt,
duke3d -map somemap.map Or if you really want to make things easy, use eduke32, they have a built in custom map selector on the main menu IIRC.
