FreeDOS is an Open Source project targeted at producing free MS-DOS compatible operating system.
These are the common uses of FreeDOS (as they are seen by creators of the project):
- 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
FreeDOS does seem to be a viable alternative in cases when original MS-DOS license was lost or old software is used but MS-DOS is not available.
I ve installed it and it seems to be a sound solution for all these old POS terminals and old machines. Well, FreeDOS is free for use anyway :-).
