When I worked as a tech, we used the drivers mostly for booting up machines to work with the Norton Ghost software. Today of course, you can use such software as Clonezilla and others. But actually there is a lot of software that can take advantage of the drivers such as a dosvnc (remote desktop viewer).You could even get software to be a mail server plus much much more.
Not many people knew that you could actually get a graphical software to view the web. Of course, you still needed to set up the packet drivers before loading in program known as Arachne. There were a few others, but they could not do as well as Arachne. Eventually a Linux version was made of the web browser.
Of course, the complement to the web browser is the web server. There are several out there including Boa which I like for old command line linux machines. Yes and even for the dos based web server you have to set up the packet drivers to get everything to work together. Only recently, did I find out about a dos based web server known as the Rubber Mallet web server. You can find out more about it at: http://www.instructables.com/id/Retro-dos-web-server/.
Actually it is quite good for little as it does. It is a good first start at learning legacy html commands. Had even planned to do some home automation with it, but moved on to other software. One thing to be aware of is all the old dos software is NOT secure. So it is best used on a private intranet. So yes, Virginia, you could set up a dos network like a mini internet!
