Welcome to FreeDOS

FreeDOS 1.2

FreeDOS is a complete, free, DOS-compatible operating system that you can use to play classic DOS games, run legacy business software, or develop embedded systems. Any program that works on MS-DOS should also run on FreeDOS.

It doesn’t cost anything to download and use FreeDOS. You can also share FreeDOS for others to enjoy! And you can view and edit our source code, because all FreeDOS programs are distributed under the GNU General Public License or a similar open source software license.

FreeDOS press kit

Are you writing an article about FreeDOS 1.2? Jim has written a press kit about the history of FreeDOS and the development of FreeDOS 1.2. With this press kit, I wanted to provide some additional information and resources about the FreeDOS 1.2 release. If you are writing an article about FreeDOS, feel free to use this information to help you. The press kit also includes a bunch of screenshots and other images that you can use.

FreeDOS in the news

Here's a brief highlight of some of the ways our upcoming FreeDOS 1.2 distribution is getting attention. Jim wrote an article "FOSS DOS for 21st Century Hardware" for FOSS Force Magazine, Generation Amiga wrote about the FreeDOS 1.2 coming at end of 2016, WatchStor described the upcoming FreeDOS 1.2 as a Christmas "gift" and ComputerWorld even mentioned FreeDOS in writing about "MS-DOS lives on after all." We'll also distribute a press kit soon, for anyone planning to write an article about FreeDOS. The RC1 and RC2 test releases were downloaded over 45,400 times in November, so thanks to everyone for testing the new version and helping us find issues before our official FreeDOS 1.2 release on December 25.

FreeDOS 1.2 RC2

We are almost ready for the new FreeDOS 1.2 release! Please help us to test this new version. Download the FreeDOS 1.2 RC2 (“Release Candidate 2”) and try it out. If you already have an operating system on your computer (such as Linux or Windows) we recommend you install FreeDOS 1.2 RC2 in a PC emulator or “virtual machine.” Report any issues to the freedos-devel email list. You can find the updated files on our download page or at ibiblio.
If you're having network problems with FreeDOS under VirtualBox, please update your VirtualBox to version 5.1.10, which fixes a compatibility bug from VirtualBox 5.1.8.

FreeDOS 1.2 RC1

FreeDOS 1.2 is almost ready, and you can help us with the final release! Please download the FreeDOS 1.2 "RC1" ("Release Candidate 1") and test it. This is a great time to test compatibility, latest versions, etc. Report any issues to the freedos-devel email list. You can find the updated files on our download page or at ibiblio.
Note: We are aware of the networking problem in VirtualBox; this may be a FreeDOS configuration issue or the packet driver being used with VirtualBox. VMware Fusion 8.1.1 works fine once the VM is configured for bridged mode.
