Introduction
This tutorial will tell you how to start writing a handy operating system. It will show you how to start doing these things. This tutorial does not attempt to explain each aspect of the operating system, and it is not necessarily the fastest, best way or trick. All source code is centered on readability without any optimization.
I assume that the readers of this book have a computer that meets the standard "PC Architecture" and has Intel X86 (or its compatible) processor. The following courses may require a processor with IA-32 Architecture (i386 to Pentium 4). Some courses assume that you use the FAT file system. Some courses need to use MS-DOS / Windows Debug tools, similar tools can work normally. I don't plan to discuss the BIOS, assembly language, and Intel or PC architecture, because you can find detailed information about these in other places. There is a manual for assembly language programming on the Intel processor on the Intel's website.
I am studying with these things, so these courses will reflect my experience, or new things I have learned. For this reason, the number of courses will continue to increase, so please come here from time to time. If you have the idea of future courses, please tell me. Also, if you have any suggestions, questions, or comments, please send me email.
