Welcome to 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.

We welcome new users to FreeDOS. You can 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.

Looking for the FreeDOS 1.1 distribution? You can help make this happen!

New web design
2009-12-31 22:13 - The FreeDOS Project
The New Year brings an opportunity for change. So to celebrate the end of 2009, and the beginning of 2010, I have posted the new web design for the FreeDOS web site. Thanks to nodethirtythree for this great update! (Note that if you are using a mobile device, you will [automatically] get a slightly different version of the new web design, optimized for mobile web browsers with limited resolution.)

Web design update
2009-12-22 18:12 - The FreeDOS Project
About 2 months ago, I posted a note asking for help with the FreeDOS web design. I didn't get much in response. In fact, only 2 people sent back a design concept. Instead, I contacted AJ at nodethirtythree design. He agreed to help me, and modified one of his existing web designs (nonzero_blue) for use on the FreeDOS web site. I think it looks great! I'll put the new design up in a few days. More info at http://www.freedos.org/jhall/ - or more directly at https://sourceforge.net/userapps/wordpress/jhall1/2009/12/22/web-design-update/
