KolibriOS is a tiny yet incredibly powerful and fast operating system. This power requires only a few megabyte disk space and 8MB of RAM to run. Kolibri features a rich set of applications that include word processor, image viewer, graphical editor, web browser and well over 30 exciting games. Full FAT12/16/32 support is implemented, as well as read-only support for NTFS, ISO9660 and Ext2/3/4. Drivers are written for popular sound, network and graphics cards.

The core parts of KolibriOS (kernel and drivers) are written entirely in FASM assembly language! Try Kolibri and compare it with such heavyweights as Windows and Linux.

KolibriOS Features
A monolithic preemptive kernel that is less than 100 kilobytes in size, complete with streams, parallel execution of system calls, a USB and TCP/IP stack.
Speed: Thanks to being (carefully) written in Assembler, it's very fast.
Size: KolibriOS is very small - The kernel and most of the programs fit on a 1.44MB floppy disk!
Filesystem support: Read/write support for FAT16/32 (with long file names) and ext2/3/4, read-only support for NTFS, XFS and CDFS(ISO9660).
Lightweight: Kolibri boots on any computer that has a Pentium (i586) compatible processor and at least eight megabytes of RAM.
Hardware support: A lot of the popular sound, network and graphics cards are supported (see supported hardware list)
Comes with a development kit (code editor with FASM macro-assembler integrated).

KolibriOS has forked off from MenuetOS in 2004, and is run under independent development since then. All our code is open-source, with the majority of the code released under GPLv2 license.
