Welcome to the PHOBOS web site. PHOBOS is a tiny operating system that runs on PC hardware. Although intended to be a demonstration system, it could be made to do real work if required. Its primary purpose, however, is to present a working operating system that is small enough for an individual to understand, and to show how various parts of the PC hardware are programmed.

For more details, see the Overview.

This site was built by, and is maintained by, Bob Eager who is the implementor of PHOBOS, and can be contacted via these pages if you would like more information.
