As part of our work this semester, we added an interesting new feature to the system. We have created what we call "Nachos/486": A stand-alone version of the Nachos kernel. Nachos/486 allows the same kernel that runs on the host operating system as a process to be re-linked (not recompiled) and run stand-alone on Intel hardware. This stand-alone operating system runs native in protected-mode utilizing some of the features of the Intel x86 architecture. Without swamping you in details of how we implemented the system, we wanted to mention it to you and see if you were interested in hearing more about it. We think the work has some real potential in that it adds a whole new and realistic dimension to the Nachos system: Simulating the operating system, and then letting it loose on the hardware. If you are interested in reading more about it, there is a small web page about it at "http://www.cs.virginia.edu/~bah6f/nachos486/". Available from that page is the report that accompanied the project, which contains summary information and some implementation details. We look forward to hearing your thoughts on the project and its potential.
