In this tutorial, we are going to install PC DOS 1.10 on DOSBox-X. If you want an introduction to PC DOS 1.10, I suggest you to read the first few paragraphs of our post <a href=\"https://old.virtualhub.eu.org/how-to-install-pc-dos-110-on-86box/\" target=\"_blank\" rel=\"noopener noreferrer\">how to install PC DOS 1.10 on 86Box</a>. DOSBox-X already emulates DOS, but we can use it to install a different version of DOS also.</p>\n<p>You need to download the following file to follow this tutorial:</p>\n<ul>\n<li><a href=\"https://winworldpc.com/download/c3acc3b4-c3b9-15c2-adc3-9611c3a5c28f\" target=\"_blank\" rel=\"noopener noreferrer\">IBM PC DOS 1.10 archive</a></li>\n</ul>\n<p class=\"msg msg--success\"><strong><span style=\"text-decoration: underline;\"><em>Note</em></span><br></strong>This tutorial uses DOSBox-X. It is not compatible with DOSBox, DOSBox-SVN or DOSBox-Staging. For DOSBox/DOSBox-SVN, see <a href=\"https://old.virtualhub.eu.org/how-to-install-pc-dos-110-on-dosbox/\" target=\"_blank\" rel=\"noopener noreferrer\">how to install PC DOS 1.10 on DOSBox</a>. For DOSBox-Staging, we will post a tutorial soon.</p>\n<h2>Creating the Virtual Machine</h2>\n<p>If you have not already installed DOSBox-X, you can install it from its <a href=\"https://dosbox-x.com/\" target=\"_blank\" rel=\"noopener noreferrer\">homepage</a>. On Linux, you can also install it from your distribution's repositories or other third-party repository for your distribution.</p>\n<p>Create a folder to store the files related to you VM. Extract the PC DOS 1.10 archive and open the extracted folder. Go to the images folder inside it and open the Raw folder. Copy the file called <code>DISK01.IMA</code> to the VM folder. You may want to rename it to something like <code>PCDOS1.10.IMA</code> to avoid confusion later.</p>\n<p>Now copy the default DOSBox-X config file to this folder. You can see <a href=\"https://dosbox-x.com/wiki/Home#_dosbox_xs_configuration_file\" target=\"_blank\" rel=\"noopener noreferrer\">this page</a> to know where the file exists on you system or you can download it from <a href=\"https://raw.githubusercontent.com/joncampbell123/dosbox-x/master/dosbox-x.reference.conf\" target=\"_blank\" rel=\"noopener noreferrer\">here</a> ( You may need to right click and click on Save As to save the file). Rename it to something suitable such as <code>pcdos1.10.conf</code> and open it in your favourite text editor.</p>\n<p>Add the following line to the end of that file:</p>\n<pre>IMGMOUNT a PCDOS1.10.IMA<br>boot a:</pre>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/31/PCDOS1.10-DOSBox-X-1.webp\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-1-xs.webp 300w ,https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-1-sm.webp 480w ,https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-1-md.webp 768w\" alt=\"DOSBox-X config file for PC DOS 1.10\" width=\"861\" height=\"665\"></figure>\n<p>Save and close the file. Open a terminal/command prompt and navigate to that folder. Now run DOSBox-X:</p>\n<pre>dosbox-x -conf pcdos1.10.conf</pre>\n<p>On Windows, you may need to add the path to DOSBox-X before this command if you have not added it to the PATH environment variable. So the command would likely become:</p>\n<pre>\"C:\\Program Files\\DOSBox-X\\dosbox-x.exe\" -conf pcdos1.10.conf</pre>\n<p>The DOSBox-X program will open and boot PC DOS 1.10:</p>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/31/PCDOS1.10-DOSBox-X-2.webp\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-2-xs.webp 300w ,https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-2-sm.webp 480w ,https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-2-md.webp 768w\" alt=\"PC DOS 1.10 on DOSBox-X\" width=\"740\" height=\"465\"></figure>\n<p>When asked for Date and time, just press enter. Do not enter anything. PC DOS 1.10 has problems with dates later than year 2000, so it is best to leave the default date set. You can enter the <code>DIR</code> command to see the list of files:</p>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/31/PCDOS1.10-DOSBox-X-3.webp\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-3-xs.webp 300w ,https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-3-sm.webp 480w ,https://old.virtualhub.eu.org/media/posts/31/responsive/PCDOS1.10-DOSBox-X-3-md.webp 768w\" alt=\"List of files on PC DOS 1.10 on DOSBox-X\" width=\"740\" height=\"465\"></figure>\n<p>You can now close that window. Now we will create a script to launch the VM. On linux create a file called PCDOS1.10.sh with the following lines:</p>\n<pre>#!/bin/bash<br>dosbox-x -conf pcdos1.10.conf</pre>\n<p>Then make the script executable by running the following command in terminal after navigating to that folder:</p>\n<pre>sudo chmod +x ./PCDOS1.10.sh</pre>\n<p>Then we can right click on that file and click on Run as Program to open the VM. Some DEs and distros may have other methods of running shell scripts.</p>\n<p>On Windows, create a file called PCDOS1.10.bat in that folder with the following contents:</p>\n<pre>\"C:\\Program Files\\DOSBox-X\\dosbox-x.exe\" -conf pcdos1.10.conf</pre>\n<p>Then double click on that file to launch the VM.</p>\n<p>That's it. We used PC DOS 1.10 on DOSBox-X. You can now close the VM window. The next time you start it, you do not need to insert the disk file again. PC DOS 1.10 will start without any problem.

You can also read the MS DOS 1.25 manual which I posted in <a href=\"https://old.virtualhub.eu.org/how-to-install-ms-dos-125-on-dosbox-x/\" target=\"_blank\" rel=\"noopener noreferrer\">its tutorial</a>, since they both are almost same.</p>\n<h2>Manuals</h2>\n<ul>\n<li><a href=\"https://web.archive.org/web/20220408191257/http://www.bitsavers.org/pdf/ibm/pc/dos/IBM_DOS_1.1_May82.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">PC DOS 1.10 Manual</a></li>\n<li><a href=\"https://web.archive.org/web/20200803043016/http://www.bitsavers.org/pdf/ibm/pc/languages/BASIC_1.1_May82.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">BASIC Manual</a></li>\n</ul>\n<p>You may also want to read the IBM PC manuals.

"content_html": "<p>In the last few tutorials, we installed MS DOS 1.25 on various emulators and hypervisors. Now we will continue with IBM PC DOS. IBM PC-DOS was an IBM branded version of MS DOS licensed from Microsoft for use on the IBM PC system. Versions of PC DOS paralleled that of MS DOS up until version 6.1, where PC DOS was independently maintained by IBM up until 7.1, the last version. Although not the only OS available for the IBM PC when it came out, it quickly became popular due to its low cost in comparison to the others.</p>\n<p>The first version of PC DOS was released in August 1981 with the IBM PC. IBM PC DOS 1.0 was a port of 86-DOS purchased by Microsoft in 1981 for use on the IBM PC. This version of DOS resembles that of CP/M at the time. 1.0 only supports single sided 8-sector 160k 5.25 inch floppy disks. 1.1 adds support for double sided 320k disks. Directory support did not exist with this version of DOS. PC DOS 1.x was a floppy-only version of DOS. It cannot be installed to a hard drive.</p>\n<p>You need to download the following file to follow this tutorial:</p>\n<ul>\n<li><a href=\"https://winworldpc.com/download/c3acc3b4-c3b9-15c2-adc3-9611c3a5c28f\" target=\"_blank\" rel=\"noopener noreferrer\">IBM PC DOS 1.10 archive</a></li>\n</ul>\n<h2>Creating the Virtual Machine</h2>\n<p>If you have not installed 86Box yet, see our tutorial on <a href=\"https://legacyinstaller.pcriot.com/vm-software/86box\" target=\"_blank\" rel=\"noopener noreferrer\">how to do so on windows</a> and <a href=\"https://legacyinstaller.pcriot.com/vm-software/how-to-install-86box-on-linux-along-with-a-manager\" target=\"_blank\" rel=\"noopener noreferrer\">on Linux</a>.</p>\n<p>Open the 86Box Manager.

It was only available to OEMs. In this tutorial we use the Columbia Data Products OEM that works well on IBM PC clones.</p>\n<h2>Creating the Virtual Machine</h2>\n<p>First you need to make sure you have installed MAME. For windows, see our tutorial on Legacy Installer on <a href=\"https://legacyinstaller.pcriot.com/vm-software/mame\" target=\"_blank\" rel=\"noopener noreferrer\">how to install MAME on Windows</a>. For linux, you can install mame from the official repository of your distribution. See <a href=\"https://pkgs.org/download/mame\" target=\"_blank\" rel=\"noopener noreferrer\">this page</a> for a list of distributions offering the package. If your distribution does not include mame in its repositories (highly unlikely), you can <a href=\"https://docs.mamedev.org/initialsetup/compilingmame.html\" target=\"_blank\" rel=\"noopener noreferrer\">build MAME from source</a>.</p>\n<p>After you have installed MAME, you need to create a folder in which all the files related to the emulator will reside. Open a Terminal/Command Prompt window and move to that folder. Then run:</p>\n<pre>mame -cc</pre>\n<p>You may need to specify the path to MAME if you are on Windows:</p>\n<pre>\"C:\\Program Files\\MAME\\mame.exe\" -cc</pre>\n<p>This command will create some basic config files for MAME in that folder. Now open the folder in your File Manager and delete the <code>mame.ini</code> file. Extract the <code>mame.ini</code> file from the archive you downloaded above according to your platform and copy it to the folder in which you are storing all the files related to the emulator. Create a folder called <code>roms</code> in that folder. Copy the ROM archives to that folder. Do not extract the ROMs from the zip files. Move the zip files without extracting to the <code>roms</code> folder.</p>\n<p>Extract the MS DOS 1.25 archive and open the extracted folder. Go to the images folder inside it and copy the file called <code>CDPDOS.IMG</code> to the folder where you are storing all the files related to the emulator.</p>\n<p>Now switch back to the terminal and run:</p>\n<pre>mame ibm5150 -flop1 CDPDOS.IMG</pre>\n<p>You need to prefix <code>mame</code> with the path on Windows as shown above. The mame window should open:</p>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/26/MSDOS1.25-MAME-1.png\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-1-xs.png 300w ,https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-1-sm.png 480w ,https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-1-md.png 768w\" alt=\"MAME with ibm5150\" width=\"702\" height=\"535\"></figure>\n<p> If the window does not open and you get a ROM not found or similar error, see the troubleshooting section below. Press any key to continue. The emulation of this machine is not perfect. You will be informed about this by MAME. Press any key to continue. It might take a long time depending on your system for MS DOS 1.25 to boot. After it has booted, you will see the following screen:</p>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/26/MSDOS1.25-MAME-2.png\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-2-xs.png 300w ,https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-2-sm.png 480w ,https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-2-md.png 768w\" alt=\"MS DOS 1.25 on MAME\" width=\"697\" height=\"551\"></figure>\n<p>When asked for Date and time, just press enter. Do not enter anything. MS DOS 1.25 has problems with dates later than year 2000, so it is best to leave the default date set. You can enter the <code>DIR</code> command to see the list of files:</p>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/26/MSDOS1.25-MAME-3.png\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-3-xs.png 300w ,https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-3-sm.png 480w ,https://old.virtualhub.eu.org/media/posts/26/responsive/MSDOS1.25-MAME-3-md.png 768w\" alt=\"List of files on MS DOS 1.25 on MAME\" width=\"697\" height=\"551\"></figure>\n<p>Now, you can close this window. Now, we can make a shell script which runs the VM on linux:</p>\n<pre>#!/bin/bash<br>mame ibm5150 -flop1 CDPDOS.IMG</pre>\n<p>and save the file as MSDOS1.25.sh. Then make the script executable by running the following command in terminal after navigating to that folder:</p>\n<pre>sudo chmod +x ./MSDOS1.25.sh</pre>\n<p>Then we can right click on that file and click on Run as Program to open the emulator. Some DEs and distros may have other methods of running shell scripts.</p>\n<p>On Windows, create a file called MSDOS1.25.bat in that folder with the following contents:</p>\n<pre>\"C:\\Program Files\\MAME\\mame.exe\" ibm5150 -flop1 CDPDOS.IMG</pre>\n<p>Then double click on that file to launch the emulator.</p>\n<p>That's it. We have installed and run MS DOS 1.25 using the MAME.</p>\n<h2>Troubleshooting</h2>\n<p>First make sure that you have placed the roms files in the correct place. Do not extract the files. Place the zip files directly in the <code>roms</code> folder.</p>\n<p>On Linux, there might be another error. MAME might have been configured to look in your <code>~/.mame</code> folder for its config files. If that is the case, running the command <code>mame</code> without any parameters in the folder where you have stored the files would result in MAME opening in full screen instead of a window. If you are affected by this problem, here is the solution:</p>\n<ul>\n<li>Configure your file manager to show hidden files.</li>\n<li>Go to the <code>~/.mame</code> folder.</li>\n<li>Delete the <code>mame.ini</code> file there.</li>\n<li>Copy the <code>mame.ini</code> file you downloaded from above to that folder.</li>\n</ul>\n<p>The <code>mame.ini</code> file you downloaded above instructs MAME to look for another mame.ini file in the current folder and use it if found. So, you can then follow the tutorial and everything will work.</p>\n<h3>Some explanation</h3>\n<p>I asked you to replace the <code>mame.ini</code> file with the one you downloaded from here. What are the differences between those files? Here are they:</p>\n<ul>\n<li>It instructs MAME to open in windowed mode instead of full screen.</li>\n<li>It modifies the key needed for enabling UI controls from Scroll Lock to Caps Lock. This is done because many keyboards do not have a Scroll Lock key.</li>\n<li>On Linux, it instructs MAME to first look for configuration files in the current directory, and if found, use them instead of the one from <code>~/.mame</code> folder.</li>\n</ul>\n<p>That is it.</p>\n<h2>Manuals</h2>\n<ul>\n<li><a href=\"https://winworldpc.com/download/c387c5b8-c38c-c38e-3ce2-809e11c3a4ef\" target=\"_blank\" rel=\"noopener noreferrer\">MS DOS 1.25 Manual</a></li>\n</ul>\n<h2>Related Pages</h2>\n<ul>\n<li><a href=\"https://winworldpc.com/product/ms-dos/1x\" target=\"_blank\" rel=\"noopener noreferrer\">WinWorld page</a></li>\n<li><a href=\"https://en.wikipedia.org/wiki/MS-DOS\" target=\"_blank\" rel=\"noopener noreferrer\">Wikipedia</a></li>\n<li><a href=\"https://www.pcjs.org/software/pcx86/sys/dos/compaq/1.12/\" target=\"_blank\" rel=\"noopener noreferrer\">PCjs page - Run MS DOS 1.25 in you web browser</a></li>\n<li><a href=\"https://betawiki.net/wiki/MS-DOS_1.25\" target=\"_blank\" rel=\"noopener noreferrer\">BetaWiki page</a></li>\n<li><a href=\"https://github.com/Microsoft/MS-DOS\" target=\"_blank\" rel=\"noopener noreferrer\">MS DOS 1.25 Source Code (Open Source) - Microsoft GitHub</a></li>\n<li>Some related YouTube videos:\n<ul>\n<li><a href=\"https://youtu.be/WtoDbu6dOC4\">https://youtu.be/WtoDbu6dOC4</a></li>\n<li><a href=\"https://youtu.be/pKcuHmpTMk0\">https://youtu.be/pKcuHmpTMk0</a></li>\n</ul>\n</li>\n</ul>\n<h2>Credits</h2>\n<ul>\n<li>The <a href=\"https://mamedev.org/\" target=\"_blank\" rel=\"noopener noreferrer\">MAME emulator</a> is an open source project hosted on <a href=\"https://github.com/mamedev/mame\" target=\"_blank\" rel=\"noopener noreferrer\">github</a> developed by MAMEDev and contributors</li>\n<li>The disk image used above was taken from <a href=\"https://winworldpc.com/\" target=\"_blank\" rel=\"noopener noreferrer\">WinWorld</a>.</li>\n</ul>",

It was only available to OEMs. In this tutorial we use the Columbia Data Products OEM that works well on IBM PC clones.</p>\n<p class=\"msg msg--success\"><strong><span style=\"text-decoration: underline;\">Note</span><br></strong>This tutorial uses DOSBox-X. It is not compatible with DOSBox, DOSBox-SVN or DOSBox-Staging. For DOSBox/DOSBox-SVN, see <a href=\"https://old.virtualhub.eu.org/how-to-install-ms-dos-125-on-dosbox/\" target=\"_blank\" rel=\"noopener noreferrer\">how to install MS DOS 1.25 on DOSBox</a>. For DOSBox-Staging, see <a href=\"https://old.virtualhub.eu.org/how-to-install-ms-dos-125-on-dosbox-staging/\" target=\"_blank\" rel=\"noopener noreferrer\">how to install MS DOS 1.25 on DOSBox-Staging</a>.</p>\n<h2>Creating the Virtual Machine</h2>\n<p>If you have not already installed DOSBox-X, you can install it from its <a href=\"https://dosbox-x.com/\" target=\"_blank\" rel=\"noopener noreferrer\">homepage</a>. On Linux, you can also install it from your distribution's repositories or other third-party repository for your distribution.</p>\n<p>Create a folder to store the files related to you VM. Make sure that the path to the folder does not include a space. Extract the MS DOS 1.25 archive and open the extracted folder. Go to the images folder inside it and copy the file called <code>CDPDOS.IMG</code> to that folder.</p>\n<p>Now copy the default DOSBox-X config file to this folder. You can see <a href=\"https://dosbox-x.com/wiki/Home#_dosbox_xs_configuration_file\" target=\"_blank\" rel=\"noopener noreferrer\">this page</a> to know where the file exists on you system or you can download it from <a href=\"https://raw.githubusercontent.com/joncampbell123/dosbox-x/master/dosbox-x.reference.conf\" target=\"_blank\" rel=\"noopener noreferrer\">here</a> ( You may need to right click and click on Save As to save the file). Rename it to something suitable such as <code>msdos1.25.conf</code> and open it in your favourite text editor.</p>\n<p>Add the following line to the end of that file:</p>\n<pre>IMGMOUNT a CDPDOS.IMG<br>boot a:</pre>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/24/MSDOS1.25-DOSBox-X-1.png\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-1-xs.png 300w ,https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-1-sm.png 480w ,https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-1-md.png 768w\" alt=\"Changing the DOSBox-X default config\" width=\"724\" height=\"545\"></figure>\n<p>Save and close the file. Open a terminal/command prompt and navigate to that folder. Now run DOSBox-X:</p>\n<pre>dosbox-x -conf msdos1.25.conf</pre>\n<p>On Windows, you may need to add the path to DOSBox-X before this command if you have not added it to the PATH environment variable. So the command would likely become:</p>\n<pre>\"C:\\Program Files\\DOSBox-X\\dosbox-x.exe\" -conf msdos1.25.conf</pre>\n<p>The DOSBox-X program will open and boot MS DOS 1.25:</p>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/24/MSDOS1.25-DOSBox-X-2.png\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-2-xs.png 300w ,https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-2-sm.png 480w ,https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-2-md.png 768w\" alt=\"MS DOS 1.25 on DOSBox-X\" width=\"740\" height=\"465\"></figure>\n<p>When asked for Date and time, just press enter. Do not enter anything. MS DOS 1.25 has problems with dates later than year 2000, so it is best to leave the default date set. You can enter the <code>DIR</code> command to see the list of files:</p>\n<figure class=\"post__image post__image--center\"><img decoding=\"async\" loading=\"lazy\" src=\"https://old.virtualhub.eu.org/media/posts/24/MSDOS1.25-DOSBox-X-3.png\" sizes=\"(max-width: 48em) 100vw, 100vw\" srcset=\"https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-3-xs.png 300w ,https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-3-sm.png 480w ,https://old.virtualhub.eu.org/media/posts/24/responsive/MSDOS1.25-DOSBox-X-3-md.png 768w\" alt=\"List of files on MS DOS 1.25 on dosbox-x\" width=\"740\" height=\"465\"></figure>\n<p>You can now close that window. Now we will create a script to launch the VM. On linux create a file called MSDOS1.25.sh with the following lines:</p>\n<pre>#!/bin/bash<br>dosbox-x -conf msdos1.25.conf</pre>\n<p>Then make the script executable by running the following command in terminal after navigating to that folder:</p>\n<pre>sudo chmod +x ./MSDOS1.25.sh</pre>\n<p>Then we can right click on that file and click on Run as Program to open the VM. Some DEs and distros may have other methods of running shell scripts.</p>\n<p>On Windows, create a file called MSDOS1.25.bat in that folder with the following contents:</p>\n<pre>\"C:\\Program Files\\DOSBox-X\\dosbox-x.exe\" -conf msdos1.25.conf</pre>\n<p>Then double click on that file to launch the VM.</p>\n<p>That's it.

DOS 1.x was very limited in what it could do. It could start applications (.COM and .EXE), and process batch files (.BAT). MS DOS 1.25 worked with 320KB floppies and did not support folders (all files had to be in the root). The command interpreter supported the following commands:</p>\n<ul>\n<li>DIR, TYPE, COPY, ERASE, RENAME</li>\n<li>PAUSE, REM</li>\n</ul>\n<p>No pipes, redirection, or device drivers were supported. The DOS API in 1.0 was very limited. MS-DOS 1.25, the equivalent of PC-DOS 1.10, was the first version licensed to OEMs beyond IBM or Seattle Computer Products.
