Welcome to OSDev.org, the largest online community of operating system (OS) developers. If you want to learn how to write your own OS we have all the information to get you started. Read our OS development wiki to learn where to start. The forums are a great place to discuss OS theory and ask for help when you get stuck. Don't forget to add a link on the OS List to your OS project once it gets going.
This website provides information about the creation of operating systems and serves as a community for those people interested in OS creation. The wiki contain articles about various OS developing subjects. For more information on the history of this site, and OSDeving in general, see the History page.
Many people are interested in the process of creating a new operating system. Many people have interesting ideas for improving operating systems. Quite a few people have a brand new embedded system dropped in their lap which, due to 'improvements', won't boot an off-the-shelf operating system, and they need help getting software running on it.
The OSDev.org wiki gives these people a place to collaborate on building new operating systems, to document technical details and useful tips and ideas for operating system development.
The registering process is a bit unusual; when you click the standard 'log in / create account' in the upper-right corner, it takes you to a page that says 'Click here to create an account', which takes to you a phpBB forum(!). You need to register at the phpBB forum, join its 'wiki' group, then come back to the wiki, which will let you log in with the same password.
The wiki is backed up every week to a downloadable archive zip file. Any content published on the wiki since 2011 must comply with Public Domain licensing.  Prior to this, a somewhat haphazard licensing existed; and included Public Domain, BSD, Creative Commons Public Domain Dedication (CC0) and Creative Commons Attribution-Share Alike licenses, and these still seem to stand (on an ad-hoc basis) for content before 2011.
