Like Monk said, the best you could hope for I guess, is a boot disc (available here at Ab) that boot your computer into dos, from where you would have to start your games manually.
Of course, that disc would need some trimming before you can take full advantage of your dos computer.
About dos commands, search google for 'dos introduction'. There's a great site for the dos newbie like the most of us.
