Does anybody have any experience in using Virtual PC to run legacy MS-DOS programs? I have a 20 year old controller I need to access that uses an MSDOS editor, which needs to get to the serial port to communicate.
I cannot seem to create a virtual CD to install the add-ons; is this an inherent limitation of DOS under virtual PC? I am using 2004; 2007 purportedly doesn't have as much support for DOS.

Are you having problems with the serial port? Why are you trying to create a virtual CD? Why not burn the install files to a cd then capture it? I have successfully gotten several DOS games to work in both 2004 and 2007. Just takes a little tweaking.

I was trying to use a virtual CD because I was not able to get to the physical device - it does not seem to be mapped to anything under the MS-DOS operating system. I suppose it is possible that I need to add a device driver for it in my CONFIG.SYS in virtual DOS, but it's been so long I don't even remember what the name for a generic CD drive is or all the syntax to install it. I doubt I could get a DOS device driver for the CD in my laptop...

as well. Also, a clean install of DOS into the VM may help too.

Should work just fine.

Alternate, win98 installed and booted into DOS mode would have the driver aleady installed.
