osFree project

Like it? Support us! Join us!

osFree is a (Free Open Source software) operating system development project, aiming to replace eventually all OS/2 subsystems with Open source analogues. It aims for OS/2 Warp 4 (Merlin) as a base compatibility system, which does not mean that we will not support features of newer (OS/2 Warp Server for e-business, eComStation and ArcaOS) OS/2 versions. This includes rewriting not only user-level code but the OS/2 kernel too.

We're collecting existing code for OS/2 subsystems for years. Also we are developing our own bootloader named FreeLdr and OS/2 personality for L4 microkernel, i.e. a number of servers, implementing the Control Program (OS/2 kernel) Interface functionality in userspace. See osFree design and development concept for more details. Visit the Chat Channel on the EFNET

Several projects with similar goals exist (or existed). Here is the brief comparison of goals and tasks of different projects.

Our project is reusing the code of many opensource projects.

I'd like to help out with the DOS commands if you need a hand. My time is limited right now but I will eventually have more time to help out on other things. I could send my resume if you want to see my background. I also have lots of hardware and software to test and play with. Email me and let me know. [email hidden for spam protect] By the way, I couldn't figure out how to get a log-on to your forums so I registered on your web site.

I sent email to you with some explanation of tasks.

According to our roadmap we are now at version 0.0.3 now. We have a general working of FreeLDR (except config parser and VBE support) for stage 0.0.2 and a working CONFIG.SYS parser for stage 0.0.3. We still are thinking about real requirements for version 0.0.4 at the present time because we have working LX parser prototype and most of IFS must be in Personality Neutral services. So, we are planning to slightly review the 0 .0.x series roadmap for better representation of our current situation and needs. Most probably, we will introduce following changes:

0.0.2 EXT2FS must be finished (in general) and boot sequence must be implemented. GRUB must be removed. MicroFSD is 16-bit (OS/2 compatible), IFS is 32-bit (not OS/2 compatible). MicroFSD must load FreeLDR and execute it. FreeLDR must load L4 kernel and root task (osFree kernel stub). LILO must not be required for EXT2FS. Done
Note: MiniFSD is absent because not required for microkernel architecture.
0.0.3 osFree kernel must parse CONFIG.SYS using file provider server (not real device driver loading) and show config tree. Done
0.0.4 LX loader and module linker (using file provider server). osFree kernel must load and execute PROTSHELL application. Not Done
0.0.5 Filesystem API implementation. LX loader must allow loading of ‘Hello, world’ task via file provider and execute it. ‘Hello, world’ task is CMD.EXE prototype. Not Done

Today we started uploading the sources to SVN with the aim to configure a common build system. As we do not yet have an own SVN-Server yet, we are using the SourceForge Server. You can find the sources at https://sourceforge.net/projects/osfree/. At the moment this is NOT fully functional, not even all parts of the sources have been uploaded. Still feel free to improve osFree

For Linux personality we can select existent Linux distribution to have as less maintaining as possible. The Linux personality isn't the main goal of the project and we don't want to lose much time for it.

The Poll about Linux personality is located here.

The dotProject portion of our site has been restored after a long time of being unable to be used by either guests or the osFree staff, upgraded as there was an oppertuinity to do so. In addition to this recently we’ve had a large amount of downtime due to some big problems with one of our host’s hard drives. But now, you can now enjoy viewing the site again and most importantly the project’s status.

The osFree web team has decided to change several things. First and foremost, unregistered users cannot comment on news stories. Secondly, the ability for you to register your own account has been disabled to prevent spam dummy accounts from registering. From now on, you must request an osFree wiki account either by contacting the admins (if you are a developer you probably already received an account from one of the admins) via email or the forums. These changes were initiated as a preemptive retaliation to a recently registered spam account.

Github Commit log


We're now at the alpha stage, which means that the current version is not feature-complete nor stable and not recommended for everyday usage. The 0.0.x release series will still stay in alpha stage, and 0.9 release series will be marked as beta, meaning a system which is suitable for every day use.

The next release will be 0.0.5, with an release date being open. See our osFree roadmap for details.
