MOROS: Obscure Rust Operating System 🦉

a little 64bit microkernel based operating system written in c++ with smp support

opuntiaOS - an operating system targeting x86, ARM and RISC-V.

An x86 monolithic kernel and operating system written in modern C++. Comes with in-house graphical applications and command line utilities, plus ports of existing software. And yes, it runs DOOM!

A modular, non-POSIX operating system for x86_64, built from scratch in C and assembly. Intended to be educational and experimental while rigorously following a Plan9-style "everything is a file" philosophy, featuring a from-scratch ACPI AML parser, EEVDF scheduler and a pseudo-capability namespace based security model.

Super-simple OS

Hobby operating system kernel currently targetting the i386 processor. Doesn't do anything useful yet. This is a read-only mirror, pull requests will be ignored.

Simple, self-contained, clean code, well-documented, hobbyist 64-bit operating system for Intel and AMD processors. It's written in Assembly (Intel syntax) and C (GNU99 Standard) in which I strive for adding comments to the source code so it could be used as a reference for future OS developers
