In OS courses around the world, the laboratory assignments usually involve looking into a simulated OS, such as NACHOS. NACHOS is a simulated machine instead of a real OS. While it is simple to understand, it runs a user process on top of a host OS and might affect a student’s understanding of the OS system. In 2002, a new OS known as OS/161 was proposed, and instead of being a simulated machine, it is built to feel like a BSD Unix OS. Currently, NACHOS is used for the Undergraduate OS course in Nanyang Technological University. In this project, OS/161 is investigated as to whether it can be used for the Undergraduate OS course Lab assignments in Nanyang Technological University. Specifically, this project implements a more robust Virtual Memory System into OS/161, in hopes that it can later be adapted for use in the Undergraduate OS course Lab assignments.
