Menuet is an operating system for IBM PC compatible computers originally conceived by Ville Mikael Turjanmaa. It is notable for fitting in a single floppy disk. It is written in FASM assembly language. Some simple higher level languages are available. The current release fits just on one floppy disk and includes a GUI, playing of WAV files, a tiny editor, an assembler, a simple TCP/IP stack and some games. The source code of all programs besides the kernel is included on the diskette.
Menuet OS is a useful tool to learn how a simple OS is constructed and to do various experiments. The applications can be programmed as well in assembler which is fairly easy because of the IA-32 environment which allows to pass the parameters to the kernel functions in the registers. The Kernel is a monolithic pre-emptive, real-time kernel and already includes video drivers.
Menuet OS comes under the GPL license.
