This project is an educational curriculum designed to teach the fundamentals of operating system development and low-level systems programming. It provides a structured sequence of lessons and code samples that guide users through building a functional kernel and bootloader from scratch, enabling a practical understanding of how software interacts directly with computer hardware.
The repository distinguishes itself by focusing on the core mechanics of bare-metal execution. It covers the implementation of essential system components, including assembly-based bootloaders that transition processors from real to protected mode, and the manual configuration of global descriptor tables for memory segmentation. Users learn to manage hardware events and software exceptions through interrupt descriptor table handling, as well as how to communicate with peripherals and render text via direct memory-mapped input and output.
The materials emphasize the internal design of processors and memory management, offering a technical reference for those studying computer architecture. The content is organized as a step-by-step learning resource, utilizing a combination of C and assembly language to demonstrate how to maintain system control without the abstraction layer of a host operating system.
