KolibriOS, or Kolibri, is a small, open-source x86 operating system written completely in assembly. It was forked from MenuetOS in 2004 and has run under independent development since.

In a 2009 review piece on alternative operating systems, TechRadar called it "tremendously impressive", noting its performance and streamlined codebase.

Features

  • Pre-emptive multitasking, streams, and parallel execution of system calls
  • Boots in a few seconds from various devices, with support for NTFS, Ext2/3/4, FAT12/16/32, exFAT, and ISO9660; can also boot from Coreboot and Windows (Windows will shut down)
  • Graphical user interface based on, and optimised for, VESA
  • Development kit: code editor with an integrated macro assembler (FASM)
  • Most distributions will fit on a single 1.44 MB floppy disk image
  • Other practical applications such as a word processor, image viewer, and web browser

  • Video: works on any card and specific drivers are available for AMD and Intel chipsets
  • Network: TCP/IP stack and certain Ethernet network cards support

Development branches

  • KolibriACPI: extended ACPI support
  • Kolibri-A: Exokernel version of KolibriOS optimized for embedded applications and hardware engineering; only few AMD APU-based platforms are currently supported.
