KolibriOS – A tiny operating system on a 1.44MB floppy

KolibriOS is is an operating system that fits on a single 1.44MB Floppy (many applications are compressed) and  runs with 8MB of Ram !!!  The surprise is that the system come with a graphical environment complete with text editors, system utilities, games, browser, media players and lots of other stuff.

About KolibriOS from Kalibri Wiki :

KolibriOS is an open source operating system with a monolithic preemptive kernel, video drivers, for 32-bit x86 architecture computers, developed and maintained by The KolibriOS Project Team. KolibriOS is a fork of MenuetOS, written entirely in FASM (assembly language). However, C, C++, Free Pascal, Forth, among other high-level languages and compilers, can also be used in user application development.
English, Russian and German versions are available.



The latest version is  introduces several kernel, applications and libraries updates. Huge networking code changes, ATI video driver, HTMLV and DOWNLOADER integration for convenient web browsing and many other improvements.

I downloaded and unziped KolibriOS and after i tried on a virtualBox the truth i get choked when i saw a 1.44MB operating system load in less than 2 seconds and contain all these software.

The distribution comes in two version – a floppy image and a disk image. The disk image is slightly larger than the floppy version at 3MB, but still incredibly small. There is no mention of hardware requirement anywhere on the site, but I guess it would run any antique piece you can find.

    This is the way IT should have evolved: the OS does not consume hardware power and makes it available for applications… The applications take their share and leave most power available to users who never wait.

    But this goes against developpers laziness and against industry: it feels so good to change all hardware of the planet every 2 to 5 years.

    Of course this hardware still runs as fine as when it was new but bloated software kills it.

    May KolibriOS become a great mainstream OS :-/
