MOROS: Obscure Rust Operating System
MOROS is a hobby operating system written in Rust by Vincent Ollivier.
It targets computers with a x86-64 architecture and a BIOS, so mostly from 2005 to 2020, but it also runs well on most emulators (Bochs, QEMU, and VirtualBox).
The first task when running the OS is to install the
filesystem on a disk (or in RAM) using the install program,
although it's possible to skip the installation and stay in read only mode.
Everything in MOROS is done from a command line interface and most programs are rather minimalist.
It has a shell:
With a few programs like find that use a regex engine to find
files or lines:
It also has a lisp interpreter:
And a text editor:
It has a network stack with two drivers for RTL81339 and PCNET cards:
It even has a chess game:
Finally here are a few commands to try it out:
