This tutorial builds upon an intermediate programmer's knowledge and explains how to design and develop a feature-rich operating system. With Developing Your Own 32-Bit Operating System, you'll not only get the theory behind basic operating system design, but also learn how to build your own operating system from scratch. Meet MMURTL, a full-featured, 32-bit, message-based, multitasking, real-time operating system that you can modify and use. In addition to learning how to program an operating system, you'll gain a general understanding of 32-bit programming and how other 32-bit operating systems work. Developing Your Own 32-Bit Operating System prepares you for the future in 32-bit systems programming.
