Why is DOS still important?
|
Twenty years ago, Jim Hall, an undergraduate physics student, started the FreeDOS project. Today, he is the IT director at the University of Minnesota-Morris and is still actively involved in the project. He said that the FreeDOS project currently has 30 to 50 active developers. Most developers contribute to FreeDOS out of intellectual challenges, such as Pasquale "Pat" Villani, who contributed the kernel to FreeDOS, who was the chief software engineer at DEC, Compaq and HP and worked on the Unix operating system for many years. One reason DOS is still important is that it allows developers to get close to the hardware. FreeDOS is more friendly to virtualization and hardware simulation than other modern operating systems - it even becomes the core of the DOSEMU emulator. Jim Hall analyzed the DOS user base two years ago and found that DOS is mainly used to run three types of programs: old software, classic DOS games and embedded systems. The core user base of DOS is much larger than most people think. There are still many companies developing programs for DOS, such as National Health Systems, which still sells pharmacy systems running on DOS. FreeDOS is not the only player in the market, there are many commercial embedded DOS vendors selling their MS-DOS compatible operating systems, and Microsoft is also supplying an embedded version of MS-DOS to device manufacturers. Because FreeDOS is close to the underlying hardware, it is used as an educational tool for serial device programming and driver development, and as a development platform for other embedded DOS environments. FreeDOS senior developer Eric Auer said that DOS is a real classic, you can run standard compilers and editors on it.
