Found myself in a situation where I needed to get DOS installed in a VM for a legacy application. Found the post below on the Parrallels forum very usefull
Wiki; Email Lists; Bugs; Source Code; Links; Contribute; History; Home; download; FreeDOS 1.2. FreeDOS is a complete operating system. For new users, we recommend. These are the ISO boot disk images available from AllBootDisks. Download the ISO image you need, and if you need assistance creating a bootable CD from.
I just install a brand new VM with MSDOS 6.22. Here is what I did:
1. Download MSDOS 6.22 installer, as an ISO file, from here: http://www.allbootdisks.com/download/iso.html
This is the trick, because trying to use floppy images was a nigthmare.
2. Create a new VM and configure it for MSDOS. In my case, I created a new VHD with 250 Mb and assigned 4 MB of RAM.
3. Configure the boot sequence to: CD, HD, Floppy
4. Connect the CD to the MSDOS 6.22 ISO image
5. Startup the VM. If Parallels ask you to connect an image file to the CD, do it again in that dialog
6. After the VM starts, you will end with an A: drive, wich is actually the CD with the MSDOS 6.22 ISO image
7. Execute FDISK and create a primary DOS partition with all the size of the disk, or do whatever partition scheme you want.
8. Restart the VM. At A: prompt execute FORMAT C: /S
9. Stop VM and change boot order to HD – CD – Floopy
10. Restart VM
11. Execute all these commands:
C:
MD MSDOS
COPY A:*.* .MSDOS /v
COPY A:CONFIG.SYS
COPY A:AUTOEXEC.BAT
COPY A:HIMEM.SYS
COPY A:CD1.SYS
12. Restart your VM and you are ready to go!!

DR-DOS/OpenDOS Enhancement Project – the OpenDOS 7.01 source code based operating system develops by Udo Kuhnt between 2005 and 2011.
DR-DOS (DR DOS up to version 6.0) is an operating system of the DOS family for IBM PC personal computers. It was originally developed by Gary Kildall from Digital Research and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. After changed the ownership of the system, later versions was produced as Novell DOS 7.
In 1996 Novel sold the system to Caldera, who changed the name to Caldera OpenDOS 7.01 and released the source code of the kernel under an Open Source license. The name of the system has been changed back to DR-DOS and the model has been changet to closed source. Caldera Thinclients, a subsidiary of Caldera which later renamed itself to Lineo, continued the development of DR-DOS as an OS for embedded systems, before they abandoned its development in favour of Linux.
DR-DOS has been bought by Devicelogics company in November 2002.
In March 2004 the Devicelogics released DR-DOS 8.0 for the embedded systems market.
In March 2004 the Devicelogics released DR-DOS 8.0 for the embedded systems market.
In July 2002, Udo Kuhnt used the source code of DR-DOS 7.01/OpenDOS as a base and started to write his own set of patches for it under a new the name of DR-DOS/OpenDOS Enhancement Project.
The last version of DR-DOS 7.01.08 was released on July 21, 2011.
