Design A Mini Operating System Using Open Source System

Abstract

Abstract: COSMOS (C# Open Source Managed Operating System) Paper provides a framework and tool-chain to develop an OS purely in managed code (C# and VB .NET). Cosmos supports integration with Visual Studio, and therefore is much easier to use. However, the framework is not rich, and therefore, there is still a lot of work to be done on OS developer side (E.g., it does not support mouse, file system etc.) In this paper, a microkernel based OS is developed using COSMOS framework for x86 based computer systems. This paper demonstrates device driver (PS/2) pointing device and GUI System. Since Cosmos does not provide support file system, mouse, keyboard, we have designed appropriate drivers for screen, mouse and keyboard. We have developed Event handlers and drivers for each device.In this part, we have developed drivers for Hard Disk and RAM to detect them in order to achieve partial fulfilment. From the development of general purpose computers, software industry has also evolved. However, there is not much improvement in OS development, as compared with other fields of software world: while other fields are enjoying power of garbage collection, OS developers are still doing their job in classic languages like C, C++ and assembly. Although there has been some research work regarding this, none of them was successful. This project is an attempt to develop a mini OS in pure managed code, particularly C# and .NET Framework 4.0.
