This might just be a new question or an old one regarding FreeDOS, but I hope someone can help. I am trying to setup a VM running FreeDOS in Parallels Desktop 12. I already have a WindowsXP VM running and it's working fine. I need this old stuff for some work programs that will not run above XP and thought, rather than buying multiple XP licenses I would set up several FreeDOS VM's with different configurations for my old software. I downloaded the FreeDOS image file (fd11src.iso file - 40.8 Mb) and have it in my downloads folder. In Parallels I select NEW and it brings me to the New Virtual Machine window. Since FreeDOS is not listed in the "Free Systems" section, I selected "Install Windows or another OS from a DVD or image file". Doing that brings me to the next screen where it asks for the Installation Image. When I locate manually my FreeDOS file (fd11scr.iso) the Parallels Wizard returns the message "Unable to detect operating system". So what am I doing wrong? I have downloaded the ".iso" file twice and both do the same thing. The FreeDOS site shows the file to be 40 Mb so I think I have a good file. Other discussions talk about setting the boot order to CD, HD then Floppy but when I go into the Parallels tools section to do this it's all grayed out. I did set up a VM without an operating system, but now it tries to boot from the IDE drive and fails. I see on other threads that others are running FreeDOS so I am hopeful. Any ideas would be appreciated. Thanks.
