There is another open-source, freely avaliable DOS emulator for Windows 2000/XP that has been generating a lot of buzz lately. Its name is “DosBOX” and it is possibly a more complete, well-coded, and lighter package than FreeDOS. Additionally, it performs a slightly different function – FreeDOS is meant to function as the operating system, whereas DosBOX operates in the application layer – in other words, DosBOX is an emulator. It runs legacy applications (i.e. great, older games) with relative ease; you may just forget it’s an emulator!
