  One of the major problems nowadays in running an old DOS game from DOS
is that you will most probably not get any sound. While display cards still
preserve old VGA compatibility, most soundcards and soundchips have long
ago dropped any SoundBlaster backwards compatibility. And even if that SB
compatibility could be somehow emulated, I bet you would have to fine-tune
those environment variables settings for hours before you get anything.
(I bet you will never get it working.)

  Also many old DOS games simply crash or hang when run in a modern PC
because modern PCs are so fast that it messes up the timing routines in
those games. The older the game, the more probable that they didn't expect
PCs to become thousands of times faster.

  There may also be other minor problems with XP's and Vista's DOS simulation
which may make the game unable to run or unstable.

  DOSBox has the advantage that it fully emulates a SoundBlaster card with
all the environment variables already set up correctly, so most if not all
DOS games supporting SB will work out-of-the-box.
