About FreeDOS:

  FreeDOS is a free DOS-compatible operating system for IBM-PC 
  compatible systems, made of up many different, separate programs 
  that act as "packages" to the overall FreeDOS Project. FreeDOS 
  aims to be a complete, free, 100% MS-DOS compatible operating 
  system (mostly achieved except Windows compatibility - Windows 
  standard-mode works on FreeDOS, but 386-mode / WfW 3.11 does 
  not.) A short list of things possible with FreeDOS today:
     * Easy multiboot with Win95-2003 and NT/XP/ME,
     * FAT32 file system and large disk support (LBA),
     * LFN support (with several tools, and FREECOM (COMMAND.COM)),
     * LBACACHE - disk cache (harddisks in CHS and LBA mode, diskette),
     * Memory Managers: (HIMEM), (EMM386), UMBPCI, HIMEMX, JEMM386,
       JEMMEX,
     * SHSUCDX (MSCDEX replacement) and CD-ROM driver (XCDROM.SYS) /
       UIDE.SYS,
     * CUTEMOUSE - Mouse driver with scroll wheel support,
     * FDAPM - APM info/control/suspend/poweroff, ACPI throttle, HLT
       energy saving,
     * (XDMA.SYS) - (UDMA.SYS) - UIDE.SYS driver for DOS: up to
        4 harddisks. UIDE.SYS also supports SATA,
     * MPXPLAY - media player for mp3, ogg, wmv... with built-in AC97
       and SB16 drivers,
     * 7ZIP, INFO-ZIP zip and unzip... - modern archivers are available
       for DOS,
     * EDIT / SETEDIT - multi window text editors,
     * HTMLHELP - help viewer, can read help directly from a zip file,
     * PG - powerful text viewer (similar to V. D. Buerg's LIST),
     * many text mode programs ported from Linux thanks to DJGPP,
     * GRAPHICS - greyscale hardcopy on ESC/P, HP PCL and PostScript
       printers,
     * NLS Support: Help (" /? ") to the commands can be shown in
       different languages (not at all commands),
     * etc.
  FreeDOS itself has NO graphic user interface (GUI). If you want to
  shutdown your computer, simply close the program you are working with
  and press the "power off" button.
