FYSOS: The Virtual File SystemThis book is Volume 2 of the series, FYSOS: Operating System Design, and will describe the process needed to connect a file system to your kernel. It explains the steps to create a file system independent link between a file system residing on the media to your kernel code. Once you have done this, a simple call to fopen("C:\filename.txt", OPEN) is all you need to open a file. It then goes into detail, giving examples of what a file system should be, how to create your own, and what to include in that file system. It also explains the process of a simple journaling file system. Part 2 of this book details four file systems, two commonly used and well known, and two hobby file systems. The companion CD-ROM contains source code to utilities to check your work, display the contents of a file system, dump a file system, and repair a file system. This book, and its continued series of books, does not expect you to build the next great wonder of the computer world. It simply will help you with your interest in controlling the computer's hardware, from the point the BIOS releases execution to your boot code to the point of a fully working Graphical User Interface. It is not required that you know much about operating system design to use this book and no specific hardware or software is required.
