MS-DOS & Software

This page contains download links for a very old Microsoft operating system so that it can be preserved -- on this corner of the Internet, anyway -- for anyone who is curious to tinker with the first versions of Windows or who just wants to take a trip down Nostalgia Avenue.

The operating systems here are distributed as floppy disk image files (with an .img extension). If you actually have a floppy drive, you'll have to flash these images onto floppy disks. If you just want to use VirtualBox, it can make use of the floppy image files directly.

Hardware Drivers for VirtualBox

These are some hardware drivers for DOS and Windows 3.x that are known to work with VirtualBox's emulated hardware. Drivers include:
  • CD-ROM driver
  • DOSIDLE to make MS-DOS stop consuming 100% CPU
  • WQGHLT to make Windows 3.x stop consuming 100% CPU
  • SoundBlaster 16 as a CD image (requires the CD-ROM driver)
