What is FreeDOS
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:
1. To run old DOS games (like DOOM, etc.)
2. To run old business software that only supports DOS
3. 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 it's most often run inside a PC emulator. You can find PC emulators for all computer platforms (Windows, Linux, Mac.) If you are new to DOS, we recommend you use an emulator to install and boot FreeDOS.
FreeDOS is open source software; you can view and edit our source code. Most FreeDOS programs are distributed under the GNU General Public License ("GNU GPL") which means they are not only open source software, but they are Free software. Because of this, FreeDOS would not exist were it not for all the people who contribute to it. Even if you didn't write code, you helped out the FreeDOS Project by submitting comments and bug reports.
We welcome new members to FreeDOS. You can help contribute to the FreeDOS Project by downloading our latest release and telling us what you think. We have a bug tracking system that helps you report problems and submit requests, and otherwise tell us how to improve FreeDOS. By participating in the development and debugging process, you help everyone.
You are downloading an entire operating system, and in most cases, you are then going to install the operating system on your computer. If you already have another operating system on your computer, it may be overwritten during the installation process. If this is not what you intend, stop now.
