KolibriOS is an open-source operating system for x86 computers, written completely in FASM assembly language. It has been developed since 2004, forked from MenuetOS, and supports i586 CPUs or newer. KolibriOS is small sized and fits on a single 3.5" floppy disk; despite this, it features a full graphical user interface, preemptive multitasking, networking capabilities, and many pieces of bundled software.
The name "Kolibri" is the Slavic word for hummingbird and symbolizes the operating system's tiny size and fast speed.
