osFree project

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 and eComStation) 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.

  • 0.0.4 release by Valery V.Sedletski (2009/09/03 07:06)
    We released this preview to show actual possibility of LX executables (native OS/2 executable file format) to be run on top of L4. Output from LX executable is "I am really small!" phrase. Other things is debug output. Our executable uses msg.dll which uses doscalls.dll. So, linking also works. Also we present here osFree loader which allow to load as Multiboot compatible kernels as native OS/2 kernel. Loader is moduler and easy to extend. Next release will provide some interactive like directory browsing and files execution. See roadmap at www.osfree.org for more info.

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.
