FreeDOS is a free DOS-compatible operating system for IBM-PC compatible systems. FreeDOS is made of up many different, separate programs that act as "packages" to the overall FreeDOS Project.
These days, there are three main uses of FreeDOS:
- To run old DOS games (like DOOM, etc.)
- To run old business software that only supports DOS
- To support an embedded DOS system, such as a computerized cash register or till
You can run FreeDOS on pretty much anything. While can run FreeDOS on a dedicated PC, now its most often run inside a PC emulator. You can find PC emulators for all computer platforms (Windows, Linux, Mac.)
