How did you run the game? I.e.: What did you click, what did you type, everything you did.

What other games did you try?

What version of dosbox are you using?

Error: Game mode indeterminate

DOOM is looking for the doom*.wad file that it needs. This could mean that you haven't installed a doom*.wad file, that more than one of doom1.wad, doom.wad, or doom2.wad is available, or that you have an incorrect setting for the DOOMWADDIR environment variable that DOOM uses to locate doom*.wad.

The name of the WAD file is significant and is used to determine what mode the game should run in, like this:

doom1.wad
Run in shareware mode (no -file switch, only the first episode is available)
doom.wad
Run in registered mode (-file switch works, three episodes available)
doom2.wad
Run in DOOM II mode (-file switch works, one episode of 32 levels)
