Floppy disk-based operating systems

MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its alternate branding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in variou

CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors.

FreeDOS (formerly PD-DOS) is a free software operating system for IBM PC compatible computers. It intends to provide a complete MS-DOS-compatible environment for running legacy software and supporting embedded systems. FreeDOS can be booted from a floppy disk or USB flash drive and is designed to run well under virtualization or x86 emulation.

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.

MenuetOS is an operating system with a monolithic preemptive, real-time kernel written in FASM assembly language. The system also includes video drivers. It runs on 64-bit and 32-bit x86 architecture computers. Its author is Ville M. Turjanmaa. It has a graphical desktop, games, and networking abilities (TCP/IP stack). One distinctive feature is that it fits on one floppy disk.

discontinued computer operating system

86-DOS (known internally as QDOS, for Quick and Dirty Operating System) is a discontinued operating system developed and marketed by Seattle Computer Products (SCP) for its Intel 8086-based computer kit.

DR-DOS is a disk operating system for IBM PC compatibles, originally developed by Gary A. Kildall's Digital Research, Inc. and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. Upon its introduction in 1988, it was the first DOS that attempted to be compatible with IBM PC DOS and MS-DOS.

CP/M-86 is a discontinued version of the CP/M operating system that Digital Research (DR) made for the Intel 8086 and Intel 8088. The system commands are the same as in CP/M-80. Executable files used the relocatable .CMD file format. Digital Research also produced a multi-user multitasking operating system compatible with CP/M-86, MP/M-86, which later evolved into Concurrent CP/M-86. When an emulator was added to provide PC DOS compatibility, the system was renamed Concurrent DOS, which later became Multiuser DOS, of which REAL/32 is the latest incarnation.

PicoBSD is a discontinued single-floppy disk version of FreeBSD, one of the BSD operating system descendants. In its different variations, PicoBSD allows one to have secure dial-up Internet access, a small diskless router, or a dial-in server, all on one standard floppy disc. It runs on a minimum 386SX CPU with of RAM (no hard drive required).

tomsrtbt (pronounced: Tom's Root Boot) is a very small Linux distribution. It is short for "Tom's floppy which has a root filesystem and is also bootable." Its author, Tom Oehser, touts it as "The most GNU/Linux on one floppy disk", containing many common Linux command-line tools useful for system recovery (Linux and other operating systems.) It also features drivers for many types of hardware, and network connectivity.
