FreeDOS (formerly Free-DOS and PD-DOS) is an operating system for IBM PC compatible computers. FreeDOS is made up of many different, separate programs that act as "packages" to the overall FreeDOS Project.[1] As a member of the DOS family, it provides mainly disk access through its kernel, and partial memory management, but no default GUI (although OpenGEM is listed on the official FreeDOS website). FreeDOS is currently at version 1.0, released on September 3, 2006.[4]

FreeDOS supports vintage hardware IBM PC as well as modern ones, in addition to embedded computers. Unlike MS-DOS, it is composed of free and open source software, licensed under the terms of the GNU General Public License (GPL). It does not require license fees or royalties and creation of custom distributions is permitted.[1] However, in its "util" section, it includes non-GPL software such as 4DOS.[2]

FreeDOS has a sparsely-populated IRC channel, #freedos, on
