moros

MOROS is a text-based hobby operating system written in Rust by Vincent Ollivier.

It targets computers with a x86-64 architecture and a BIOS, drawing inspiration from Unix, Plan 9, and DOS to provide a simple and efficient environment for computing and communication from the command line.

What's new in MOROS 0.12.0?

  • Replaced the frame allocator to support large amounts of memory
  • Optimized file::write append operations to improve large file support
  • Added FileIO::write to ATA devices to write bootloader and kernel to disk
  • Added a kernel package
  • Added zlib support with deflate and inflate commands
  • Added INI file parsers to standardize system configuration
  • Added multiple buffers support in the editor
  • Added <path>:<row>:<col> support in the editor and error messages

How to run MOROS?

The binary can be booted from USB on a computer with a BIOS or from a virtual machine with Bochs, QEMU, or VirtualBox. Here's a quick way to do it with QEMU:
