Most likely your keyboard is going bad if keys are not working, I doubt DOS all of the sudden does not acknowledge them. What would you like to upgrade to? Windows, Linux? This is a Unix forum, you may get some general info on how to upgrade to x86 unix OSes but are not likely to hear much about Windows or Dos.
