I believe you have already read my article about How to install MS-DOS 6.22 in virtual box. Now, I will guide you how to install CD driver in MS-DOS 6.22.

Below are the steps:

1.Download the CD driver.
2.Create an floppy disk image.
3.Create a virtual floppy disk drive.
4.Mount the image file to the floppy drive.
5.Copy the driver.
6.Unmount and remote the virtual floppy disk.
7.Run DOS in the Virtual box.
8.Edit AUTOEXEC.BAT file.
9.Edit Config.sys file.
10.Reboot the DOS system

Step 1. Download the CD Driver
First, you have to download the CD/DVD driver.
The driver is oakcdrom.sys. You can get it from http://www.scriptco.net/rr/cdrom_info.htm
Then you have to copy it into a floppy disc image or a CDrom.
The easy one is just create an floppy disc image and copy the driver into it.

Step 2. Create a Floppy disk image
Open your Linux terminal.
Change your access to root.
Create a 1.44 MB floppy disc using linux command “mkfs.msdos“. It will create an MS-DOS file system under linux.
-Option “-C” is used to create the new file system in a file instead of a real device.
-Option “1440“ is the size of the floppy disk image.

$ mkfs.msdos -C myfloppy.img 1440
mkfs.msdos 3.0.9 (31 Jan 2010)

option -C means, create the file given (myfloppy.img) as device.
1440 means, the size is 1.44MB.

Let’s check the result.

$ ls -l myfloppy.img
-rw-rw-r-- 1 darklinux darklinux 1474560 2019-05-16 05:07 myfloppy.img

Good, now you have a floppy disk image.

I will explain to you how to install MS-DOS 6.22 (Microsoft Disc Operating System version 6.22) in virtual box. This version supports cd/dvd driver, usb and network.

If you want to play the old DOS games or old DOS applications, it will easier for you.

Before we start, few things you have to do:
1. Download the MS-DOS installation images from the link below:

There are 3 images files that represent 3 floppy discs. The extension file is .img.

Rename it to .dsk.
So, it will become:

There are few process that need to be done.

-Create the virtual hard disk
-Create the hard disk partition
-Format the hard disk

Now, we can start to install this operating system in VirtualBox. MS-DOS doesn’t need much space. So, 100MB hard disc space is enough to play around. But if you want to add the networking on it I suggest to provide 200MB hard disc space. For memory you can use the default 32 MB.
