Getting Started

Prerequisites

Before you begin, make sure you have the following:

• A computer with a suitable development environment.
• Basic knowledge of programming languages like C/C++.
• Familiarity with computer architecture and assembly language is a plus.

Setting Up Your Development Environment

1. Choose a Host Operating System: You'll need a host OS to build and test your operating system. Common choices include Linux or macOS.
2. Install a Cross-Compiler: To build code for your target architecture, you'll need a cross-compiler. Popular options are GCC for cross-compiling to x86 or ARM.
3. Version Control: Set up a version control system like Git to track your project's changes.
4. Emulator or Virtual Machine: Use an emulator like QEMU or a virtual machine (e.g., VirtualBox) to test your OS.

Creating Your First Bootloader

Your bootloader is the first code that runs when a computer starts. Here's how to create a simple bootloader:

1. Write bootloader code in assembly or low-level languages like NASM or Assembly.
2. Compile your bootloader code.
3. Create a bootable disk image with your bootloader using tools like dd on Unix-based systems.

Building the Kernel

The kernel is the core of your operating system. Start by:

1. Writing kernel code in your chosen language (e.g., C/C++).
2. Compiling your kernel code with the cross-compiler.

Booting Your OS

1. Combine the bootloader and kernel to create a bootable image.
2. Test your OS on an emulator or virtual machine.

Further Resources

• Explore online OS development communities and forums for guidance and problem-solving.
• Study textbooks and online resources related to OS development.

Conclusion

You've taken your first steps into OS development. Remember that this is just the beginning. OS development is a challenging but rewarding journey. Stay curious, keep experimenting, and happy coding!

Remember to regularly update your documentation as your OS project evolves.
