Introducing New VirtualHub! https://blog.virtualhub.eu.org/a-fresh-restart/

Introduction In the last post we described the process of creating a DOS 6.22 virtual machine. But that VM is far from perfect. If you were curious, you might have even tried to open DOSSHELL and fond that it does not work properly. So, in this tutorial we are going to show you how to optimize DOS 6.22. Note that this tutorial does not refer to any virtualization software in particular and is applicable to all of those which are supported by us. For a list, see the VM Software tag. If you have not already installed DOS 6.22, see our tutorial on - How to install DOS 6.22 on VirtualBox? Files Needed CD Driver floppy image Utilities ISO CD Driver As you might have experienced, installing software from different floppy images can be very tiresome. So, I have created a special ISO disk image with all the needed software. But DOS 6.22 does not contain CD support by default. So we need to enable it. Yo

Introduction Originally 86-DOS, written by Tim Paterson of Seattle Computer Products, DOS was a rough clone of CP/M for 8086 based hardware. Microsoft purchased it and licensed it to IBM for use with Microsoft's IBM PC language products. In 1982, Microsoft began licensing DOS to other OEMs that ported it to their custom x86 hardware and IBM PC clones. Microsoft DOS 6.22 was the last standalone version from Microsoft. It was also the last from Microsoft to run on an 8088, 8086, or 286. 6.22 adds DriveSpace, a replacement for DOS 6.20's DoubleSpace drive compression that was removed in 6.21.

Introduction In the last tutorial, we installed DOS 3.31 on DOSBox. We were unable to install Word 5.5 on it due to several problems as discussed in that tutorial. So, in this tutorial we are going to install Word 5.5 directly on DOSBox. We are able to do so because DOSBox emulates its own version of DOS by default. The Microsoft Word word processor was first introduced for MS-DOS in 1983. Its design made use of a mouse and WYSIWYG graphics. Its crude WYSIWYG/mouse support was a direct response to the Apple Lisa/Mac, and VisiCorp Visi On. Initially it competed against many popular word processors such as WordStar, Multimate, and WordPerfect. Word for DOS was never really successful. The DOS, Mac, and Windows versions are quite different from each other, and each restarted their version numbering at "1.0". Later versions are bundled with Microsoft Office.

In 1982, Microsoft began licensing DOS to other OEMs that ported it to their custom x86 hardware and IBM PC clones. MS-DOS 3.31 was only sold through a few OEMs, mainly Compaq. This version adds support for hard drives up to 512MB. It also does not use as much conventional memory as DOS 4.x or later, making it a good choice for 8088/8086 based computers. You might be wondering why you would want install DOS on DOSBox. It’s a fair question, because DOSBox has its own DOS-like environment, and supports the DOS API which allows many applications such as classic games to be run without the user needing to own a copy of DOS. But maybe there is something which is not currently supported by the DOSBox environment, or perha
