Run DOS on the Raspberry Pi – Use rpix86 to turn your Pi into a 1980s super-computer.

This tutorial is not intended for absolute beginners. It requires the use of the Raspian terminal commands which is text based, so some skill with Linux is useful.

Please feel free to jump straight to the ‘DOS on the Pi‘ if you have no interest in a computer history lesson.

What is DOS?

DOS was a semi-open standard that included a common operating system for desktop computers in the 1980s and early 1990s. The hardware used Intel x86-compatible CPUs while the operating system for this architecture was DOS the Disk Operating System. Note that the DOS acronym was also used for a number of incompatible and unrelated computer systems such the Apple DOS and Atari DOS.

As DOS was a primitive, text only operating system that was easy to reverse-engineer. A number of companies made their own editions of DOS and for the most part they were all compatible with each other. The most common x86-edition of DOS was Microsoft‘s MS-DOS but IBM also had their own PC-DOS as did Digital Research with DR-DOS.

MS-DOS was Microsoft’s precursor to its Windows operating system. In the 1990s many editions of Windows were simply a layer of software designed to load up after MS-DOS or later contained MS-DOS built-in.

Off the shelf x86-compatible hardware combined with the DOS operating system became the prominent computer gaming system in North America from the late 1980s until Windows 95. Other regions such as Europe preferred cheaper, propriety systems such as the 8-bit Commodore 64, Amstrad CPC, Sinclair Spectrum. Or the equally as expensive but more user-friendly 16-bit Atari ST and Commodore Amiga lines. In these parts of the world x86-compatible computers only became popular after the early 1990s.

How did DOS come to be?

DOS started out as a clone of the early microcomputer operating system CP/M by Digital Research. CP/M was created in 1973 to run on the Intel Intellec-8 development system which happen to be the first microcomputer sold in the USA.

By the end of the 1970’s CP/M was the most popular microcomputer operating system for professionals and business. Once IBM decided to enter this burgeoning market they wanted to use CP/M on their future products but they couldn’t come to an amicable agreement with Digital Research.

So IBM asked Microsoft to develop a clone of CP/M for their first microcomputer that they dubbed the Personal Computer or the PC. But at this early stage of its life Microsoft had never developed an operating system but bluffed IBM to believe otherwise.

Microsoft discovered a small software company known as Seattle Computer Products who had a x86-compatible CP/M clone called 86-DOS. Microsoft signed a non-exclusive contract to market and distribute this operating system and on-sold it to IBM. Just weeks before IBM’s major PC public announcement Microsoft obtained near-exclusive rights for Seattle’s 86-DOS.

In August of 1981 IBM launched the IBM PC. A machine that bought mainstream attention to microcomputers and made them respectable in the eyes of the public. Every IBM PC sold was operating off a royalty-free copy of Seattle Computer Products 86-DOS operating system re-branded as PC-DOS.

IBM had always been a hardware company and believed there was little money in software. Apple to this day follows that same ethos. What IBM failed to realise was they had designed their machine with off the shelf parts that anyone could buy. The only thing other manufactures lacked to create their own PCs was the operating system. But due to IBM’s non-exclusive operating system agreement. Microsoft was free to re-brand their own version of IBM’s PC-DOS and to sell it to potential companies who wanted to make copycat IBM PCs. That small mistake by IBM launched Microsoft, who became one of the world’s largest companies.

Why DOS?

Many popular franchises, genres and software companies were first launched or popularised on DOS. Warcraft, Grand Theft Auto, Sid Meier’s Civilization, Monkey Island, X-Com, Need for Speed. The first person shooter, the graphic adventure, simulators, real-time strategy are some examples. So DOS would be well worth investigating for anyone who has an interest in retro-gaming from this era.

Why not DOS?

It must be said that the DOS ecosystem has to be the most complicated and arcane mainstream gaming system of all time. The same openness that made it popular was also what made it so horrible to use.

Backwards compatibility was a major benefit and selling point of the DOS ecosystem. But at the same time it held it back and made it much more complicated than necessary. By the late 1980s, its text based 1970s lineage was horribly primitive and outdated.

Hardware support was complex. Often users had to manually change and configure their operating system for each item of software they ran. What unfortunately started off as a simple and clean system for IBM in 1981 evolved into an ad hoc open platform that it was never designed for.

Worse was hardware driver support. For the most part new hardware had to be directly supported by software. This meant that a user’s existing game collection would often not support new hardware simply because it didn’t exist when the software was written.

Finally many game developers targeted the lowest common denominator hardware. This meant you could have had the latest and most expensive hardware yet it could have been ignored by new release software that was designed for a machine that was 5+ years old.

Fortunately much of this hardware complexity is now avoided when using software emulation such as rpix86 on the Raspberry Pi.

King’s Quest V from 1990 was one of the first titles to fully embrace IBM’s Video Graphics Array with upto 256 colours on-screen.
By 1992 some games such as Links 386 Pro had embraced hi-resolution Super VGA graphics.

DOS today?

DOS is still used on embedded systems that need a simple and small, text only operating system. Today most of the DOS community centres around the open source FreeDOS that offers modern tools as well as legacy compatibility.

DOS on the Pi.

At the time of writing in April 2013 the only acceptable DOS emulator for the Raspberry Pi is rpix86 by Patrick Aalto found at http://rpix86.patrickaalto.com.

What PC hardware does rpix86 emulate?

CPU: 80486 processor, including the protected mode features (for running DOS4GW games) but without virtual memory support. The emulation runs at a speed of around 20MHz 80486 (which equals a 40MHz 80386) machine.
Memory: 640KB of low memory, 4MB of EMS memory and 16MB of XMS memory.
Super-VGA graphics, with a maximum resolution of 640×480 with 256 colors.
SoundBlaster 2.0 (including AdLib-compatible FM sounds) sound card.

This combined hardware could have belonged to a very expensive high-end PC in the very late 1980s. Or a more affordable and common mid-range PC in the early 1990s. In that later era the audio would have been the machine’s weakest point. The graphics and memory would have been very good while the CPU would have been average.

My article DOSBox Sound Emulation talks about the huge variety of audio options on the x86-compatible platform while DOSBox Graphic and Machine Emulation covers the variety of graphic modes.

What operating systems does rpix86 support?

Unfortunately only the obscure 4DOS is supported by rpix86. 4DOS is a rather full featured and complex edition of DOS created by a small company out of Germany. While it was great for daily users of DOS based PCs back in the 1990s. It is an overkill for our purposes of PC gaming emulation on the Pi.

4DOS downloads http://www.4dos.info/v4dos.htm

Raspberry Pi set up.

This guide assumes that a clean install of Raspbian is in use on the Raspberry Pi.

Raspbian can be obtained from http://www.raspberrypi.org/downloads
A guide for installing Raspbian to an SD card for use with the Raspberry Pi is at http://elinux.org/RPi_Easy_SD_Card_Setup


Start your Raspberry Pi with a new install of Raspbian and at the Raspbian Raspi-config configuration tool do the following.

First select update to make sure you’re using the latest version of the configuration tool.
Select expand_rootfs so the free space on the SD card is fully utilised.
Select change_timeszone to set your Pi’s time zone.
Select boot_behaviour and set Should we boot straight to desktop? as No.
Select change_pass to change the default pi user password.
Select <Finish> to exit.

Now in terminal if you ever need to return to Raspi-config.

sudo raspi-config

Now lets update Raspbian and any out-of-date software.

sudo apt-get upgrade -y

DOS set up.

We are going to use a directory called /dos located in our pi home directory /home/pi/ to store our rpix86 related files. For the commands shown below ~/ in Linux is treated a short-cut for the pi user home directory.

mkdir ~/dos
cd ~/dos

mkdir ~/dos
mkdir ~/dos

This /dos directory will also double up for a mock hard drive that rpix86 will use for DOS.

Download the latest version of rpix86 the DOS emulator.

wget http://rpix86.patrickaalto.com/rpix86.tar.gz

wget rpix86.tar.gz
wget rpix86.tar.gz

Now uncompress and run rpix86. Please note that rpix86 will not work over a remote terminal connection such as SSH or Telnet.

tar -xf rpix86.tar.gz

rpix86 running under a remote terminal connection.

When prompted press Y to download the required 4DOS.COM command interpreter.

Basics of DOS shell.

At its core a DOS shell is essentially a self-contained program that allows commands to be run from a text prompt. It lets you interact with your computer’s file system and some hardware. By interacting with the file system you can launch programs; move, copy or delete files and modify the directories.

The rest of the DOS operating system comes in the form of extra programs, applications and hardware drivers that usually reside in a subdirectory. These additions can vary between different releases and iterations of DOS.

DOS command prompt explained.


C: Is the active drive. In DOS each floppy, CD, DVD or hard drive is assigned its own drive letter. The C: drive is usually reserved for the first hard drive while A: and B: are reserved for floppy drives.
\ Is the active directory. When a backlash is displayed the active directory is at the root of the drive.
> Is the beginning of the text prompt.
_ Is a blinking prompt that shows where the user’s typed input will display.


Please run the following commands in the DOS prompt. Note that unlike Linux, DOS  is not case sensitive.

List the current directory.


Display some basic 4DOS information.


Clear the screen.


Make a new directory named TEST.


Copy the file 4DOS.COM to the TEST directory.


List the content of the TEST directory.


Change the active directory to TEST.


Delete the file 4DOS.COM


Change the active directory to root.


Remove the directory TEST.


You can use the [Tab] key to auto-complete the names of files and directories that exist in the active directory.

4d [Tab]

You can cycle through previous commands typed at prompt by using the up and down arrow keys.

Quit rpix86.

Dumb DOS names.

DOS uses the FAT file system. The legacy FAT16 file system was first introduced into MS-DOS 4.0 and used through the late 1980s and early 1990s. It is horribly dated but can still be read by modern operating systems.

Because of its age FAT and DOS has a number of particular but important to know traits.

  • In DOS file and directory names can be at most 8 characters long. An additional identifier extension can be given but that can only be up to 4 characters and the first character must always be a period.
  • File usage is identified by extensions, many of which are still in use today. FILE.TXT is a plain text document. FILE.MP3 is an MP3 audio track. FILE.AVI is a video file. FILE.HTM is a HTML document. DOS script files use the .BAT (batch processing) file extension. Program files use .EXE (execute) or the .COM (command) file extensions.
  • Files and directories are case insensitive.
  • The backlash \ character is used to separate directory and file paths.

Fetch and use DOS software.

For the purposes of this article I will only use games sourced from the excellent DOS Game Archive. It only offers DOS software that is legal to distribute and use without payment.

Under the Copyright laws of many countries, copyright on software remains active until 50 or 70 years after an author’s death. This is designed to protect any potential long-term income and the resale value of a product.

The majority of dated, commercial computer software has no financial value and is usually long out of print. This is more apparent with software created for obsolete systems such as DOS. Copyright of this type is rarely defended by its owners and is unofficially known as abandonware.

While the act the downloading and use of abandonware is classed as piracy and is officially illegal. I personally do not see any serious legal or moral issues with downloading and using out of print, obsolete commercial software. But you should use your own judgement.

Where to get games?

You can find legal to download DOS shareware, freeware and public domain games at the DOS Game Archive http://www.dosgamesarchive.com.

To find abandoned but technically illegal to download DOS software, type DOS abandonware into Google and go from there.

DOS Demo 1 – LucasArts, Day of the Tentacle Demo

The surreal and funny Day of the Tentacle was a huge success for LucasArts in 1993. This non-interactive demonstration is easy to run and shows the old DOS low resolution VGA graphics and SoundBlaster audio hardware at its best.

At the Raspbian Linux terminal prompt create the directory DOTTDEMO.

mkdir ~/dos/DOTTDEMO

Change the active directory to DOTTDEMO.

cd ~/dos/DOTTDEMO

Use wget to download the Day of the Tentacle demo from DOS Game Archive.

wget ftp://download.dosgamesarchive.com/tentacle.zip

wget http://image.dosgamesarchive.com/games/tentacle.zip

Uncompress the demo file using unzip.

unzip tentacle.zip

Return back to the /dos directory and run rpix86.

cd ..

Now in the rpix86 DOS prompt list the content of the DOS root to make sure the DOTTDEMO directory exists.


Change the active directory to DOTTDEMO.


List the content of DOTTDEMO but only display items that use the extension .EXE which are execute programs.


Run the program DOTTDEMO.EXE.


Congratulations, hopefully you have a working Day of the Tentacle demo.

To exit the demo press [Alt] X and follow the prompt.

wget DOTT
wget tentacle.zip

DOS Demo 2 – Sierra Online, Space Quest 3.

From early 1980s to the 1990s Sierra Online were all about pushing the envelopes of audio and visuals on the home computer. Space Quest 3 in early 1989 was certainly doing that on the PC. Unfortunately but common for the era, this demo requires a rather complex set-up procedure.

At the Raspbian Linux terminal prompt create the directory SQ3DEMO.

mkdir ~/dos/SQ3DEMO

Change the active directory to SQ3DEMO.

cd ~/dos/SQ3DEMO

Use wget to download the Space Quest 3 demo from DOS Game Archive.

wget ftp://download.dosgamesarchive.com/spaceq3.zip

wget http://image.dosgamesarchive.com/games/spaceq3.zip

Uncompress the demo file using unzip.

unzip spaceq3.zip

Return back to the /dos directory and run rpix86.

cd ..

Now in the rpix86 DOS prompt list the content of the DOS root to make sure the SQ3DEMO directory exists.


Change the active directory to SQ3DEMO.


List the content of SQ3DEMO but only display items that use the extension .EXE which are execute programs.


Run the program INSTALL.EXE to tell the demo of Space Quest 3 what hardware our DOS machine supports.


In the Sierra Game Setup/Installation Program.

Press [Enter] at the Sierra’s newest products .. notification.

Select EGA/VGA with RGB monitor.

Select AdLib Music Synthesizer Card.

Select IBM or IBM-compatible keyboard.

Press [Enter] at the NUMLOCK is OFF confirmation.

Select NO for the MicroSoft compatible mouse.

Press [Esc] to skip the install the game on your hard disk.

Press [Enter] at the Installation is complete prompt.

Back at the DOS prompt list the content of SQ3DEMO but only display items that use the extension .BAT which are script files. Many older Sierra games used batch script files to launch their programs.


Run the batch script SQ3DEMO.BAT to launch the Space Quest 3 demo.


Welcome to Scenes From Space Quest III.

To exit press [Esc] to bring up the in-game menu and then select File > Quit.


Demo 3 – Windmill Software Digger

Next up is the rather simple Digger created by Windmill Software in 1983. The basic graphics and primitive audio was amazing compared to many early games created for the original IBM PC machines of this era. This game looks to be inspired by the 1982 Universal arcade game Mr. Do! Currently there is some audio emulation issues with this game when used on rpix86.

At the Raspbian Linux terminal prompt create the directory DIGGER.

mkdir ~/dos/DIGGER

Change the active directory to DIGGER.

cd ~/dos/DIGGER

Use wget to download Digger from DOS Game Archive.

wget ftp://download.dosgamesarchive.com/digger.zip

wget http://image.dosgamesarchive.com/games/digger.zip

Uncompress the game file using unzip.

unzip digger.zip

Return back to the /dos directory and run rpix86.

cd ..

Now in the rpix86 DOS prompt list the content of the DOS root to make sure the DIGGER directory exists.


Change the active directory to DIGGER.


List the content of the directory DIGGER.


Run the program DIGGER.EXE.


Welcome to computer video gaming 1983 style. Use the arrow keys to control your character or to exit Digger press [F10] a couple of times.


Demo 4 – Non-working Games

At the moment rpix86 is still an immature product and your mileage for running various software will vary. Some DOS software can be temperamental such as Epic MegaGame’s Zone 66 from 1993. It demands that we do not load any DOS XMS memory drivers but currently we can not do this in rpix86.

At the Raspbian Linux terminal prompt create the directory ZONE66.

mkdir ~/dos/ZONE66

Change the active directory to ZONE66.

cd ~/dos/ZONE66

Use wget to download Zone66 from DOS Game Archive.

wget ftp://download.dosgamesarchive.com/zone66.zip

wget wget http://image.dosgamesarchive.com/games/zone66.zip

Uncompress the game file using unzip.

unzip zone66.zip

Return back to the /dos directory and run rpix86.

cd ..

Now in the rpix86 DOS prompt list the content of the DOS root to make sure the ZONE66 directory exists.


List the content of ZONE66 but only display items that use the extension .EXE which are execute programs.


Run the program ZONE66.EXE.



Disappointingly we receive an abort error message This program can not run with an XMS driver!!! because our DOS operating system is not configured correctly. As you can see gaming on PCs in this era often required more technical knowledge than today.


Well that is it for this tutorial. I will continue to update this entry as new revisions of rpix86 are released for the Raspberry Pi. Feel free to ask any questions in the comments below.

  1. Thankyou for this guide. I tried your demo tentacle and it worked! I have so far got kens labyrinth and the winnie the pooh game working off dosgamesarchive.com. I have been trying various full version games to see what will work. So far the supernova text game, black cauldron and trolls cave will not run. I can not seem to find the exe file to run them after I download, the elder scrolls game arena when I try to run it will say needs win32, daggerfall also wont run.

    1. Hi Jackie I unfortunately can’t help you with specific games downloaded off the Internet.

      But for your other problem Win32 means it requires Windows 32bit API. It is a technical catch-all name for Windows 95, Windows 98 and Windows ME so Daggerfall is a Windows game that will not work in MS-DOS.

  2. I am about to install this on a Pi and have a couple of questions:
    1. Will this run any DOS-based program? I would like to run DWJukebox on the Pi.
    2. I have developed a MOUSE (usb) replacing buttons with my custom buttons. Will the DOS pick up my USB mouse?

    I think it is great that people like you take the time to bring back older tech!

    1. Hi Aubrey, I hope your DOS Pi experiment worked out.

      To answer your questions briefly, no the odds are this set up will not run every DOS program but it should run many of them.

      And yes since rpix86 0.5 mouse emulation and support is included.

      The long answer: One of the problems with DOS on the Pi is that the whole DOS PC including CPU, graphics and audio is emulated in software. A traditional DOS PC used an Intel compatible x86 CPU (8088,8086,286,386,486, Pentium/586 etc) while the Raspberry Pi uses an incompatible ARM based CPU which traces its linage to the old RISC processor designs. So this means any DOS emulator on the Pi has a lot more work to do converting the CPU and hardware instructions that are used by the DOS applications and that allows opportunities for further bugs and incompatibilities.

  3. I have tried to install this program on my Raspberry Pi but each time I attempt tp download the tar file, I get this
    Resolving rpix86.patrickaalto.com ( rpix86.patrickaalto.com)… failed: Name or service not known
    wget: unable to resolve host address ‘rpix86.patrickaalto.com’

    Can anyone help??

  4. Thank you Ben, I got it working. The net was indeed down.
    I have one new problem
    I tried downloading and running Dale Harris’s “Cash Register”, it is a DOS programme that runs on a windows machine and is only 2.7 MHz download and is 6 MHz when unpacked. Also I cant seem to get it to run at all in the rpix86 emulator
    Thanking you in advance

  5. Hello Ben, This is a great emulator. Thanks for making it available. – I have a Dos program on a floppy disk/USB stick. How would I copy it into the emulated dos environment please? Is it possible to use configs.s and auto sec.bat like the original Dos? Thanking you in advance – kind regards Steve

    1. Your Pi should be able to read the USB. But you will need to do that using Raspbian (Linux).

      Check this post under the heading ‘Connecting and Mounting a USB Flash Drive’ to learn how to access your USB drive under a Pi.

      Once it is mounted you will need to copy the content from the USB stick to your Raspberry Pi SD based drive. The Linux copy command CP should suffice.

      This will copy a single zip file.zip to the dos sub-directory within your home directory.

      cp /dev/[USB_DEVICE_NUMBER]/mnt/usb/file.zip ~/dos/

      Or to copy the whole USB stick you could use the recursive option.

      cp -R /dev/[USB_DEVICE_NUMBER]/mnt/usb/* ~/dos/myusb

      For a brief introduction on all the options for cp

      cp –help

      For the cp command’s manual.

      man cp

      A floppy disk will be a little more complicated as you’re probably going to have to extract ‘rip’ the software from the floppy disk and make sure it will still operate. You maybe best off to see if you can find a pre-ripped version of the software on-line for download. Google ‘dos abandonware’ and go from there.

  6. Hello Ben
    Refering to my post (#7), I have downloaded the program iand tried running it on the Rpi with rpix86 but it will not run when I try typing the .exe file for instance pos71j.exe
    So right now I a stuck, can you help??

    1. Unfortunately if it’s not working then there is not much you can do. Remember Rpix86 is an emulation software design to run DOS software designed for an Intel x86 CPU on a completely incompatible ARM (mobile phone) processor. So it definitely will not run every DOS program out there.

      But make sure you are using the lasted version of Rpix86 (version 0.11) as it is a continuous work in progress.

      You may also wish to get in contact with Patrick the author and see if he can determine what the problem is with Free POS and release a fix in the future.
      http://rpix86.patrickaalto.com/index.html see ‘Contact me’

      Sorry I can’t be of more help.

  7. Hey-
    I have been trying to install the top two games in your examples or demos, and they install and start; however, both games just play the intro in repeat over and over and I cannot seem to start the gameplay on any games. (DOTT and Space Quest III). Any advice?

    1. Hi Leo, both games are working as intended. I offered the demos versions of the games as a proof of concept to test that those commercial DOS game engines work on the Pi. Unfortunately it is illegal to offer for download the complete editions of the games.

      You can legally buy a digital copy Space Quest 3 from Good Old Games. http://www.gog.com/game/space_quest_1_2_3
      But DOTT would have to be sourced from EBay or a 2nd hand shop.

  8. Hi Ben,
    I’d tried to install the dos and it works.
    But every time when I run the game demo, it just hang up.
    I am using putty to SSH my Pi. I’d tried to use VNC and run it in Terminal, but it still hang up.

    1. Hi Wilson, you can not use SSH or VNC to remotely login to a networked Pi to run DOS games. You need to have a monitor and a keyboard/mouse connected directly into the Pi and interact with it using those peripherals.

  9. Hello, great tutorial, but I have a couple of issues. first, you walk us through running rpix86 for the first time, but I had a bit of trouble getting it to run a second time. a couple of lines added could help.

    A bit about how to add games you already have would also help (I just rebooted back to the GUI and dropped the game folders into the Dos directory)

    Im pretty good with computers I got my first one 36 years ago, but, I’m brand new to the PI, and some of this took some work. A total noob would need more help.

    Do you know if there is anyway to make the PI just boot straight into Rpix86/4dos without having to mess with commands? A batch file of some sort?

    1. Hi Doug, thank you for the feedback as it is always appreciated. The guide is definitely not for noobs and I’ve updated the intro to reflect that. Like home computers of the 1980s, the Pi has limited resources. So I was forced to use the text terminal and disable the GUI to improve the performance of the DOS emulation.

      What kind of trouble you were having in getting rpix86 to run a second time (I assume after a reboot)?

      Did you know Raspbian is a slimmed down port of Debian Linux created specifically for the Raspberry Pi? So the guide was written for those with some skill in Linux but were maybe new to or unfamiliar with DOS, rather than the other way around. Linux is a very rewarding environment to learn once you get past its learning curve.

      For file transfers I found the `wget http://example.com/somefile.zip` download command was the simplest way to get software onto rpix86. Because to be honest, there are so many possibilities for transferring files that I figured it was best to let the reader to work out their own solution.

      1. Hi.

        I haven’t touched this in months, but i got back to it this evening.

        Your instructions are great for downloading, unpacking, installing, and then running dos. But, when you reboot the pi to play later you don’t need to download, unpack, and install – you just need to run it and it took me a good twenty minutes of playing around to figure out how to do that.

        In my case it was 2 commands

        cd dos (where dos was the name of the directory I installed this stuff in)
        ./rpix86 (it was the ./ that really had me stumped)

        then I had my C: prompt and I’m playing Kings Quest like I was 12 again.

        (i’ve written that on a bit of paper taped to my Pi for future refernce)

        Is there anyway to set things so that it just does that automatically when I turn it on?

        BTW, Im 43 and have had a computer since I was 6. I have some programming experience, some Linux experience and lots of hardware experience. I’m new to the Pi, but new tech does not scare me.

        1. Hi Doug,
          Great to hear you got Kings Quest running on your Pi! I too used to be a massive Sierra Online fan as a child; Space Quest 2 was one of the first games I ever owned.

          One problem I find with writing blog posts is they can become bloated too much information and turn readers off, so you have to be on the point.

          In the DOS setup, chapter it does say where the rpix86 application will be stored, how to access it.

          We are going to use a directory called /dos located in our pi home directory /home/pi/ to store our rpix86 related files.

          cd ~/dos

          And how to run rpix86.

          Now uncompress and run rpix86.


          I do agree it is a little subtle and I did assume most people would pick up on the keywords, especially since both DOS and Linux terminal share a similar procedure.

          1. I’m not good at subtle. But, I did work it out in the end. and, I can see how you wouldn’t want to make an already long tutorial longer, but one sentence inserted just before “Basics of DOS shell.” would work, something like “the next time you want to run this simply type “cd dos” to change to the dos directory and “./rpix86” to start the emulator.
