Look at some of the alternatives that you have today if you want to build a small embedded device: DOS, Windows CE (and there's a reason they call it "wince"
, or an embedded Linux (ala Elks). Look at it a little more closely, and you'll see that if space becomes an issue for you, DOS is really the only way to go. Linux and Windows both require too much overhead to build an efficient embedded system. Another thing that will keep DOS around, even behind the scenes, is the PC market. A lot of companies that make computer hardware (disk arrays, video cards, controller cards, etc.) use some kind of BIOS. (This is just an example.) Now, the way of the operating system is to make it free, and for more and more operating systems to become available and popular (right now, looking at my friends and people around the office, we use: Windows 95/98, Windows NT, Linux, FreeBSD, FreeDOS.) The hardware manufacturer may not care exactly what operating system you use. After all, they provide hardware, and others may provide the software drivers that make use of it. At some point, you'll need to provide a patch, and the user will need to flash the BIOS on their device. If you are the hardware manufacturer, how do you distribute a flash update to all your users? Will you provide a different update program for every operating system platform that might be using your hardware? In my quick list, I count five different operating systems. Will you create five different versions of your update program, and provide support on all those platforms (remember also that the Windows NT credo is "thou shalt not touch thy hardware"
? For a lot of companies, the answer is no. It's a lot simpler if they can give their users a bootable floppy disk that they put into their computer, and the boot floppy automatically flashes the BIOS. Want to help us?
