Additional information Published by Microsoft Mobile. SCP later sued Microsoft, claiming that they had concealed its relationship with IBM in order to purchase the operating system cheaply.

Paterson denied any wrongdoing. I just took his printed documentation and did something that did the same thing. His conclusion? In the meantime, a team of Microsoft programmers that included company co-founder Paul Allen was working on a major revision to add hierarchical subdirectories, and to support the hard disks that would be available on the IBM PC-XT.

DOS 2. MS-DOS continued to be enhanced until the late s, by which time Windows and other advanced operating systems with graphical user interfaces had taken over. An operating system that fits in 12 or 28 Kbytes of memory is very different from the large and complex operating systems we use today.

MS-DOS was basically a file manager and a simple program loader. The operating system really had a good welcome when it was released into the market as it packed all the features that were lagging in the then present operating systems. Now the phenomenal traces of such a sophisticated operating system cannot be run over on a normal base computer system and that is where we jump into the conclusion of running the same MS-DOS operating system in a virtual machine.

Virtual Machine is a great concept that allows you to run an old, new and advanced operating systems in the same computer by just booting the Image file of the required operating system in the loader.

There are a lot of virtual machine providers out there that will help you with getting a Virtual machine set up. You can also download the image file of a virtual machine from the ISO river page and get the download done. Some of them are;.

The features that we experience with the operating system these days seemed to be ab ideal one back in those days of MS-DOS. You can also download the installer for a virtual machine by accessing the link to download a virtual machine into your computer. Since the operating system that you are going to run is MS-DOS, the configuration of the system can is kept to the minimal requirements that I have mentioned below. Once you are one with the configuration you will have to download the MS-DOS installer from the mentioned link below as an ISO image and boot the same into the virtual machine.

Why write this in ? That's a very valid question, to which there are a few answers:. Honestly, if you have no appreciation for old hardware or software, then this is definitely not for you. If, however, you share my passion for technology, not only for the new hotness [1] of today but also the old and busted and tried and true of yesterday that got us to where we are today, then I think you'll find this interesting.

If you have some old hardware lying around then I hope you'll follow along, but even if not I think you may still find some of this interesting enough to read. It's a great project that I highly recommend.

Note: I provide download links for all discussed software in the relevant section where it's discussed. Links point to the original download location for each file wherever possible, but for the files that no longer have an official source or a reliable one, in the case of the files hosted on Microsoft's amazingly unreliable FTP server , I've linked to a local copy you can download instead.

Tip: I also recommend grabbing a copy of either Universal Extractor or 7-Zip if you're running Windows on your main computer, or p7zip and LHa for UNIX if you're running Linux both should be available in your package management system. These applications should cover all the software I tried to unpack, so having these tools available in advance will save some time and hassle.

You can get by with only one floppy diskette by writing the next disk image after the previous one completes installation, but I highly recommend using at least two diskettes so that you can have a copy of Disk 1 on hand at all times. You'll likely need to boot from or otherwise use that disk a number of times. Since it's free, though, there really isn't a good reason to not upgrade. It's larger than a single floppy, and meant to be downloaded and run directly on the target computer, which is difficult for a freshly installed version of MS-DOS.

To workaround, I suggest the following:. This disk is not mandatory, and mostly just includes some extra features from previous versions of DOS that were dropped for version 6. If you don't want to bother with it you won't be missing out on much, but just to be thorough let's take a look at how to install the more interesting stuff on here. One reason, and one reason alone: QBasic Nibbles!

I spent many hours playing this relatively simple but addictive Snake-like game as a kid, and was delighted to discover it on the supplemental disk. To try it yourself, just run qbasic. It's essentially a primitive Windows-like or perhaps more accurately, 'Windows Light' environment that runs on top of DOS and provides a GUI file manager, file associations, a menu-driven task list, and even primitive pseudo-multitasking called Task Swapper here.

It's not something I'll care to use, but it's a pretty interesting idea that I was completely unfamiliar with before this project, and it seems like it could be a reasonably powerful interface if a little time is spent on configuring it just right though, honestly, running Windows 3. I'm not going to dive into this here as it's beyond the scope of ' mostly pure MS-DOS', but here are a couple tips if you want to play around with this:.

Next, I recommend installing a couple utilities that will make the rest of the setup process much easier. As with the step-up files above, getting the files to the system is still annoying at this point. Until we get networking setup later on, I recommend unpacking the programs on your main computer and copying them over with floppies as the easiest option. Tip: You will be repeatedly hand editing your system configuration files throughout this walkthrough, and it's very possible at some point that you may be stuck with a system that won't boot properly.

This will perform a clean boot of the system, ignoring your autoexec. You can then edit them as appropriate to fix the problem, and reboot to load everything again.

To get started, edit c:autoexec. Note: Most DOS commands and options are not case-sensitive. While most of the text in the stock autoexec. My personal naming convention, used throughout this document, is pretty simple: variables are fully capitalized, and almost everything else is lowercase.

Feel free to leave everything uppercase if that works for you, though. SmartDrive is 'a disk caching program LOADHIGH will load the specified program when possible into upper memory, freeing up the all important conventional memory for other applications.

This requires that EMM also be enabled, as shown below. The c:dosnet directory doesn't exist yet, but will shortly. Finally, the DIRCMD variable instructs the DIR command to display files sorted first by name, then by extension, with directories always listed first by default, it lists files sorted by date.

I also modified TEMP, pointing it to c:temp to make it more general purpose; ie. Next, edit c:config. Note that this shortens the amount of time you have to press F5 if you need to clean boot your system, but it's still possible if you're fast, or you hold down F5 right before DOS starts loading which is what I do. I discuss this a bit more in the Addendum below. I recommend rebooting at this point to let the new configuration take effect.

NIC Drivers you'll need to grab drivers for your specific NIC; these drivers cover my system, and will be used for the walkthrough :. Now it's time to finally configure networking. Getting this up and running is extremely helpful because it largely eliminates the need for floppy disks. Unfortunately, networking under DOS is It can be done, but it's somewhat limited, slow, and painful to install due to multiple driver and network protocols.

So, get ready for some fun! The first decision to make is to decide what kind of networking support you want installed. In brief, there are two types of drivers we're going to install:. NDIS - the newer device driver interface co-developed by Microsoft, with somewhat more features and capabilities at the expense of more bugs and significantly more memory usage. This is required for Microsoft networking utilities, including support for drive mapping.

Most non-Microsoft network utilities require a packet driver interface and will not work with only NDIS installed. Fortunately, this isn't a one-or-the-other choice; it's possible to install support for both with some extra work. If you only need one or the other, though, save yourself the hassle and go with that one. I'm going to walk through installing both below, and point out what you should do differently if you only want to install one of the drivers. For the full experience it's worth setting up NDIS it can be cleanly disabled if you decide it's not worth it , but if you just want to get up and running as quickly is possible, the PD-only option should suffice, and is all I use on my system after experimenting with all of this.

Download the appropriate driver package for your NIC and consult the documentation for details. This file can be manually unpacked, but it's probably easiest to use QStart to unpack them for you:.

If you only want to install the PD interface, copy the packet driver to c:dos. Edit c:autoexec. The 0x60 option for each specifies the software interrupt; 0x60 is the default, and there shouldn't be a reason to change it unless you're using multiple NICs. Run the above command now to manually load the driver; assuming you have an ethernet cable plugged in, it should automatically detect the connection.

NDIS driver installation is quite a bit more involved. It can be installed manually like the PD, but instead we're going to let installation and configuration be handled by Microsoft Network Client 3. To prepare for setup, copy both MS-Client disks to your hard drive as noted above, I recommend keeping a copy in c:backup as well - last time I'll mention this. Running each EXE file will unpack them to the current directory if you didn't unpack them before hand.

If prompted, it's safe to overwrite any files as a few exist on both disks assuming you copied the MS-Client disks to their own directory. Note: If you are using a 3c90x card, you must edit oemsetup. Comment out or delete the following lines and save the file:.

A bug in the MS-Client installer prevents a file necessary for Windows 3. This isn't necessary if running solely under DOS, but it doesn't hurt in anyway, so let's install it just to be safe. To do so, from the msclient setup directory run: expand disk2wsahdapp. If you run into any other trouble, or have questions about some of the options, official MS-Client setup documentation is still available from Microsoft.

MS-Client updated your system configuration files during setup, so let's review those changes and make a couple changes. First, edit config. These are some of the various network services installed by MS-Client. We're requesting that they load themselves into high memory. This indicates you've run out of upper memory, and MS-Client isn't smart enough to load itself into conventional memory instead. This is only required if you plan on mapping shared drives, and can be disabled if you do not wish to auto-mount drives at login.

If you do plan to mount shared drives, go ahead and enter your username now or just press Enter to accept what you specified during MS-Client setup , then enter the password for your account.

In either case, choose Y to create a password list when prompted. We can perform a few tests to confirm, but note that the utilities described below, though named the same as modern utilities, work differently than what you're probably used to again, think 'primitive'. Next, make sure you can ping your own IP, eg. The bottom line should say 'echo received'. Finally, make sure you can ping your gateway's IP address this can be found in the ipconfig output :.

Again, the bottom line should say 'echo received'. If all that worked, congrats, you're up and running! However, there's one more major issue we need to take care of. Due to another bug in MS-Client, DNS does not work by default, nor is it possible to configure or enable it through the setup utility; this must be done manually.

Substitute the appropriate values for your network, and be sure to separate the octets with spaces as shown above rather than periods as would be done on modern systems. Finally, run the above command now to start the Microsoft domain name resolver. You can verify DNS is working properly with ping again:. All of this work will now let us finally do something very important: map shared network drives. This is especially useful as we can use this to easily copy files and install new applications and drivers without floppy disks.

To map a drive, assuming you already have a shared drive properly configured in Samba or a Windows server which is outside the scope of this HOWTO , run:. Again, assuming everything has been properly setup on the server, and that you logged in with proper credentials, this should just work; you'll get a 'command completed successfully' message if it did. To test, try running dir e: and verify that you get output. If it doesn't as expected, and you followed all instructions above, the error is most likely on the server side.

I've had mixed results myself - on my initial testing with MS-Client about three years ago , I was able to get this working perfectly with Samba; this time, however, I can't.
