Hello Jordan, I have not tried all the possible combinations myself, and there are caveats, e.g. you have to choose between VirtualPC XP mode Win7 or VirtualPC 2007 64-bit (a complete uninstall of XP mode is necessary if you try VirtualPC 2007), VirtualBox and VirtualPC 2007 64-bit can coexist, but cannot be run at the same time, if hardware virtualization is enabled. I am running Win2000 with hardware virtualization enabled in VirtualBox and MS-DOS and Win 3.1x in VirtualPC 2007 with hardware virtualization disabled concurrently without problems. I very much like VirtualBox W2K which has great additions and seamless windowing support in Win7, I use the shared folder approach for information sharing between systems which is very good in VirtualBox, and I have a HP Jetdirect network printer attached (there is no LPT1 support in VirtualBox). VirtualPC 2007 download 32-bit and 64-bit versions available: http://www.microsoft.com/en-us/download/details.aspx?id=24439 more links at: http://www.essjae.com/virtualization/default.htm VirtualPC 2004 additions that can be installed from a DOS command line, see my page: http://www.lexitec.fi/xywrite/utility.html under: DOWNLOAD http://www.lexitec.fi/xywrite/dosadd.zip Installing MS Virtual PC and Virtual Machine Additions for MS-DOS. Includes installation instructions and a modified DOSADD.BAT compatible with MS-DOS.
