# MOROS
|
|
|

|
|
|
|
|
MOROS is a hobby operating system written in Rust for the x86 architecture.

It targets 64 bits processors with a legacy BIOS, so roughly computers from the
|
|
|
|
|
2010 era, but it also run well on most hypervisors.

|
The first task when running the OS is to install the
|
|
|
|
|
[filesystem](filesystem.md) 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
|
2021-08-01 11:03:29 +00:00
|
|
|
rather minimalist.
|
|
|
|
|
|
2021-08-12 21:15:28 +00:00
|
|
|
It has a [shell](shell.md):

|
With a few programs like `find` that use a [regex engine](regex.md) to find
|
|
|
|
|
files or lines:

It also has a [lisp](lisp.md) interpreter:

|
|
And a [text editor](editor.md):

|

It has a [network stack](network.md) with two drivers for RTL81339 and PCNET cards:

It even has a chess game:
