Windows 2000 does NOT support dos, although, there is a way to get some dos games to work on windows 2000 such as Viper Racing(published and developed by Sierra). I know that as a fact for I have got it to work on Win 2k and it is a dos based game. If you have viper racing and you are trying to get it to work on win 2k, then go to
http://www.members.shaw.ca/nhra/ at that site you can get a beta patch, and instructions on how to get it to work. to get it to work without the cd, go under "properties" on a shortcut to the Viper Racing.exe, and go to "shortcut". where it says "target", after the link(ie: "C:\Viper Racing\Viper Racing.exe") put a space, then "-nocanary".
and if ANYONE has a way to get the game "Sorry!" to work on win 2k, it would be appreciated if you would tell me.
