...The project uses x86 assembly and C to illustrate concepts, making it accessible to students and hobbyists interested in low-level programming. By compiling and running the examples with tools like QEMU, learners gain hands-on experience with OS fundamentals. With its structured lessons and approachable explanations, the repository has become a widely recommended resource for operating system beginners.

...The materials break down historically compact and dense code into digestible segments, with diagrams and call flows that trace execution from bootloader to user space. By focusing on a small, early kernel, the series reveals core OS concepts without the complexity of modern subsystems. It highlights how segmentation and paging cooperate, how system calls are dispatched, and how context switches and signals work in practice. The commentary ties C and assembly listings back to architecture specifics, making the hardware–software interface concrete. For learners, it serves as a guided tour that builds intuition for operating system design and prepares them to tackle contemporary kernels with better mental models.

This project provides a step-by-step educational guide on building a simple operating system kernel entirely from scratch, specifically targeting the Raspberry Pi 3. The operating system, referred to as RPi OS, is inspired by the Linux kernel but remains intentionally minimal to focus on clarity and teaching fundamental OS concepts. Each lesson introduces a kernel feature and demonstrates its implementation within RPi OS, followed by a comparison to how the same concept is realized in the...

Autor ANTONIO CARLOS NICOLODI, 38 anos na área de informática como: Analista de sistemas, desenvolvedor de softwares em várias linguagens de programação: C++, Assembly, Pascal(Delphi), Basic, Cobol, Clipper, Java, etc. Refiz esta nova versão e estou disponibilizando GRÁTIS o: "VISUALG 3.0". Entre outras : (novo layout, nova roupagem até 05 tipos de peles) e novos comandos, também reconhece comandos em português correto: ( PARA ... FAÇA, SE .. ENTÃO .. SENÃO) e o operador lógico NÃO, mas em maiúsculo e os comandos antigos ainda são reconhecidos para manter a compatibilidade. ...

Simplest of possible kernel for iterative time division multithreading on smallest AVR boards Arduino. This is a small and adapted part of the future "Like OS".

Editor, criador e interpretador de Algoritmos escritos em Portugol. Ensina brincando, mostra a memória enquanto vai executando o algoritmo e vendo os processos. O Portugol não é uma linguagem de programação, é só uma Pseudo-linguagem que ensina a criar programas de computadores. E o VISUAL-G 3.0 é a ferramenta de interpretação de portugol no Brasil e no mundo! Você pode mudar as roupagens em tempo de execução, também pode ajustar cores, fontes,...

Graphical OS Kernel compiled with gcc 4.6.1 and nasm 2.09.08

SOPA is an hobby opensource operating system written in both C and Assembly. The first purpose of this project is for me to learn and hopefully help other when learning about OS development. Feel free to contribute!

It is a minimal linux like kernel for x86 architecture. It is mostly the source code from the tutorial "Roll your own toy UNIX-clone OS" written by James Molloy: http://www.jamesmolloy.co.uk/tutorial_html/index.html It is encoded in a bash script.
