user: I want to write a modern operating system from scratch for AMD64 systems with your assistance. I want you to guide me through the entire process by giving me detailed step-by-step instructions, writing code for me and telling me exactly where to put it while I provide you feedback. Where do I start?

assistant: Writing an operating system from scratch can be a challenging and complex project. However, I'd be happy to guide you through the process and provide you with some resources and suggestions. Here are the steps you can follow:

1. Familiarize yourself with the hardware: Before you start writing your operating system, you need to have a good understanding of the hardware you will be working with. This includes the AMD64 architecture, the CPU and memory architecture, and the various peripheral devices that you will need to support.
2. Decide on a design and architecture: The next step is to decide on the design and architecture of your operating system. This includes deciding on the structure of the operating system, how it will manage memory and processes, how it will handle input and output, and how it will interact with the hardware.
3. Choose a development environment: You will need a development environment in which to write your operating system. This could be a combination of an operating system and a programming language, such as Linux and C, or a specialized environment like an operating system development kit.
4. Write the boot loader: The boot loader is responsible for initializing the hardware and loading the operating system into memory. You will need to write code for the boot loader, which will be responsible for initializing the hardware and loading the operating system into memory.
5. Write the kernel: The kernel is the heart of the operating system and is responsible for managing the hardware and software resources. You will need to write code for the kernel, which will handle memory management, process management, device drivers, and other tasks.
6. Develop system calls and libraries: The operating system will need to provide a set of system calls and libraries that applications can use to interact with the hardware and other system resources. You will need to write code for these system calls and libraries, making sure that they are easy to use and well-documented.
7. Develop drivers and other hardware support: Your operating system will need to support various hardware devices, such as disks, keyboards, mice, and displays. You will need to write drivers and other code to support these devices and ensure that they work correctly with your operating system.
8. Test and debug: Once you have completed the initial development of your operating system, you will need to test and debug it thoroughly. This will help you identify and fix any bugs and ensure that your operating system is stable and functional.

Writing an operating system from scratch is a complex and challenging project, but it can be a rewarding experience and a great way to learn about the inner workings of computers. If you have any questions or need help with specific parts of the process, don't hesitate to ask.

user: Break down each step into appropriate sub steps.

assistant: Sure, here's a more detailed breakdown of each step:

Familiarize yourself with the hardware:

Research the AMD64 architecture, the CPU and memory architecture, and the various peripheral devices that you will need to support
Read relevant literature and articles to gain a deeper understanding of the hardware components and how they interact with the software
Experiment with the hardware and run tests to get hands-on experience
Decide on a design and architecture:

Research and compare different operating system designs and architectures
Decide on the structure of your operating system and how it will manage memory and processes
Decide on how your operating system will handle input and output and interact with the hardware
Outline a high-level design for your operating system and its components
Choose a development environment:

Research the different development environments available for operating system development
Choose a development environment that meets your needs, such as a combination of an operating system and a programming language, or a specialized environment like an operating system development kit
Install the development environment on your computer and familiarize yourself with its tools and features
Write the boot loader:

Research the boot loader process and how it works with the operating system
Write code for the boot loader that initializes the hardware and loads the operating system into memory
Test the boot loader to ensure it works correctly and is able to load the operating system into memory
Write the kernel:

Research the functions and responsibilities of the operating system kernel
Write code for the kernel that manages the hardware and software resources, including memory management, process management, device drivers, and other tasks
Test the kernel to ensure it works correctly and is able to manage the hardware and software resources as expected
Develop system calls and libraries:

Research the system calls and libraries used by applications to interact with the operating system
Write code for a set of system calls and libraries that applications can use to interact with the hardware and other system resources
Document the system calls and libraries, making sure they are easy to use and well-documented
Test the system calls and libraries to ensure they work correctly and are able to interact with the hardware and other system resources as expected
Develop drivers and other hardware support:

Research the drivers and other hardware support needed for the various devices supported by your operating system
Write drivers and other code to support these devices and ensure they work correctly with your operating system
Test the drivers and hardware support to ensure they work as expected and are able to interact with the hardware and other system resources
Test and debug:

Thoroughly test your operating system to identify and fix any bugs
Debug any issues found during testing, using tools and techniques as needed
Repeat the testing and debugging process until your operating system is stable and functional
Document any known issues or limitations of your operating system and plan for future updates and improvements.
