Os01
This project is an educational resource and technical reference for building operating systems from scratch. It provides a comprehensive guide to mastering x86 architecture and implementing core kernel components by writing code that executes directly on hardware without the support of standard libraries or operating system abstractions.
The materials focus on low-level systems engineering, teaching users how to interpret technical datasheets to manage hardware resources. It covers the fundamental mechanics of bare-metal programming, including the use of assembly language to define execution flows, the configuration of memory layouts through linker scripting, and the direct manipulation of processor registers.
The curriculum encompasses the architectural requirements for system-level development, such as transitioning processors into protected memory modes and establishing hardware-assisted multitasking. It also details the implementation of interrupt-driven communication, enabling the kernel to respond to asynchronous peripheral signals and manage inter-processor events.
The repository includes instructional guides on debugging techniques for low-level environments and provides a structured approach to constructing functional operating system components. All documentation is provided as a set of technical references designed to facilitate the study of hardware-software interaction.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
