FYSOS: The System CoreThis book is for those who are building an operating system, or want to start building one. This book takes you from the first step to the last step to create a minimal multi-threading protected mode OS with a round-robin style task scheduler, memory allocator, etc., as well as retrieving all the information you will need before the switch to protected mode. This book is for those who want to start but have no idea where or how to do so. Full source code is included as well as many utilities, all with source, to build your system. It is designed so that once you have this minimal system up and running, you can then start adding all of the items you need to make it a fully functional operating system. Part 2 contains an example of a more detailed memory allocator, just an example on how to add to this operating system. Chapter 11 gives an example of creating the link between the kernel and the devices and file systems attached. The remaining books in this series explains in more detail these devices.

Information Information in the book or on the CD-ROM may include Information
• The Boot Process. How and where your code starts. • Partitioning a hard drive. You have full control of the media. • Details and/or C Source code to: • A20 line • BIOS services • Booting from CD-ROM's • Detecting available memory • Quirks of the boot process • Tasking/Threading • Memory Paging • Legacy Hardware: RTC, PIT, PIC • Newer Hardware: APIC, ACPI, HPET • Multiprocessor detection • UEFI BIOS and booting with this new interface Suggested information you will need prior to reading this book are readily available: • All Specifications needed are linked within the book and freely available on-line. • You will need moderate knowledge of Assembly Language programming • along with other system related knowledge It is not required that you have extensive knowledge of Operating System Development. This book explains in detail how to get started, even if you have little or no knowledge of OS Development. Amazon now has a "Look Inside" of the first few pages of the book including the Contents showing in a bit more detail what is referenced in the book. Please note that the Kindle version is still at the first Edition and may or may not be updated to the latest edition. Only the printed form is current.
