# MOROS: Obscure Rust Operating System



![screenshot](doc/images/moros.png)



MOROS is a hobby operating system written in Rust by [Vincent Ollivier][0].



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).



This project started from the [seventh post][1] of the second edition of

[Writing an OS in Rust][2] by Philipp Oppermann and by reading the

[OSDev wiki][3] along with many open source kernels.

## Features



- External bootloader (using [bootloader][4])

- x86 CPU support (using [x86_64][5])

- Hardware interrupts (using [pic8259][6])

- PS/2 Keyboard with customizable layout (using [pc-keyboard][7])

- VGA Text mode with customizable font and color palette

- Serial output (using [uart_16550][8])

- Paging

- Heap allocation (using [linked_list_allocator][9])

- ACPI shutdown (using [acpi][10] and [aml][11])

- RTC clock

- PCI devices

- ATA PIO mode

- Random number generator (using [rand_hc][12])

- Intel PRO/1000, RTL8139, and AMD PCNET network cards

- DHCP/IP/TCP/UDP/DNS/HTTP network protocols (using [smoltcp][13])

- Basic [filesystem](doc/filesystem.md)

- Basic [shell](doc/shell.md)

- Basic [text editor](doc/editor.md)

- Basic [lisp](doc/lisp.md) interpreter

- Basic userspace for NASM and Rust programs

- Some file and [network](doc/network.md) commands

- Some [games](doc/games.md)



## Documentation



Documentation is available [here](doc/index.md)



## Setup



You will need `git`, `gcc`, `make`, `curl`, `qemu-img`,

and `qemu-system-x86_64` on the host system.



Clone the repo:



    $ git clone https://github.com/vinc/moros

    $ cd moros



Install the required tools with `make setup` or the following commands:



    $ curl https://sh.rustup.rs -sSf | sh -s -- -y --default-toolchain none

    $ rustup show

    $ cargo install bootimage



## Usage



Build the image to `disk.img`:



    $ make image output=video keyboard=qwerty



Run MOROS in QEMU:



    $ make qemu output=video nic=rtl8139



Run natively on a x86 computer by copying the bootloader and the kernel to a

hard drive or USB stick (but there is currently no USB driver so the filesystem

will not be available in that case):



    $ sudo dd if=target/x86_64-moros/release/bootimage-moros.bin of=/dev/sdx



MOROS will open a console in diskless mode after boot if no filesystem is

detected. The following command will setup the filesystem on a hard drive,

allowing you to exit the diskless mode and log in as a normal user:



    > install



**Be careful not to overwrite the hard drive of your OS when using `dd` inside

your OS, and `install` or `disk format` inside MOROS if you don't use an

emulator.**



## Tests



Run the test suite in QEMU:



    $ make test
