Welcome to the Valecium OS project! This documentation provides everything you need to understand, build, develop, and use Valecium OS.

Valecium OS is a Unix-like, multi-architecture operating system kernel designed with clean architecture, modularity, and educational value in mind. Whether you’re a curious learner, a systems developer, or someone interested in OS internals, this documentation will guide you through the project.

Quick Start

Project Overview

Valecium OS is built with the following principles:

  • Multi-architecture support — Designed from the ground up to support multiple CPU architectures (i686, x64, ARM64, etc.)

  • Clean separation of concerns — Hardware abstraction layer (HAL) isolates platform-specific code

  • Modular design — Each subsystem (memory, filesystem, drivers) is self-contained

  • Well-documented — Code and systems are documented for learning purposes

  • Performance-oriented — Practical optimizations without sacrificing clarity

Documentation Files

For Developers and Contributors

These documents cover everything needed to participate in Valecium OS development:

  • devel.ad — Coding standards, naming conventions, assembly strategy, and git workflow

  • kernel/index.ad — Deep dives into kernel subsystems, memory management, scheduling, and device drivers

  • bootloader/index.ad — Understand how does the legacy BIOS and new UEFI boot works

  • roadmap.ad — Planned features, known limitations, and architectural goals

New contributors should start with devel.ad to understand the project’s coding standards and build system.
