Hmm I've got a coupla-thousand old dos games, but not that one.
Normally I just make a shortcut to the game, then right-click, select properties, compatibility and choose win98. I've only just gotten my xp computer and its not switched on right now, but I think you can change the config and autoexec settings on a per-game basis.
I've never used dosbox because all my games are still on my win95 pc (haven't tried moving them over yet).
