Many people didn’t even know that a utility called MS-DOS Shell shipped with the extras disk of MS-DOS versions 5 & 6. It was a handy file manager which looked and operated similarly to File Manager in Windows. One of it’s most interesting features was its ability to ‘swap tasks’. I’ll show you how to enable task swapping, and how it works, as well as give you a brief overview of the use of Dosshell overall.

For years, I thought that it was impossible to access any more than 640K ‘Conventional’ RAM on my PC or XT. I was wrong. This time on Al’s Geek Lab, we see why and how the PC only addressed 640K, as well as how to take it up to 1MB without any major work.
