Design of an Operating System with In-memory Kernel

This paper lays out different issues and solutions in the design of an operating system with an in-memory kernel - from the minimum features required for a program to become the kernel, to how this kernel should be written into the boot sector of a disc so that it gets loaded into the memory. It highlights how this operating system can be made to support user specific authentication, keyboard and monitor. This also lays out the specifications for a shell to issue system commands, interfacing FAT file system and how to communicate with another similar system using serial port.
