XOS is a multi-tasking operating system for PCs which implements the x86 32-bit architecture. It provides many features found in Unix and VMS. It has a relatively small footprint but still provides a fully protected multi-tasking environment. The basic system is command line oriented and the tools needed to implement a graphical user interface are provided.

It has been used in a number of embedded/dedicated applications and can also be used as a desk-top system.

XOS itself is in the public domain. There are no restrictions on use, including commercial use. The XOS distribution includes several freeware packages that have some restrictions on redistribution, mainly requiring including copyright notices and crediting the original authors. To the best of our knowledge, all of these allow use for private or commercial purposes and free redistribution with minimal conditions. None of the software provided here is licensed under the GPL or LGPL. Please see the Legal page for a list of the external packages included and the terms and conditions under which they can be used and redistributed.

The goal for XOS has been to provide maximum practical functionality while remaining understandable, simple, secure, and efficient. (Probably "secure" should be listed first, but we believe that a system cannot be secure if it is not understandable. To be understandable it must be reasonably simple.)
