Hi: Sorry for the confusion. Virtual PC 2007 works fine with Win 95. However, Virtual PC (or Virtual PC 7), the latest version that only works with Windows 7, does not have a floppy interface. You need to open Windows Powershell and run either a VB script or Powershell script: http://blogs.msdn.com/virtual_pc_guy/archive/2009/10/01/using-floppy-disks-with-windows-virtual-pc.aspx http://social.technet.microsoft.com/Forums/en/w7itprovirt/thread/62f8eaf1-23f9-497e-a431-f4a1ad643d38 You can install Virtual PC 2007 in Windows 7, but not concurrently with VPC 7, so you lose XP mode. I am NO virtualization expert, but from my understanding, Virtual PC 2007 does not use hardware virtualization. One possibility is that the CPU speed is sensed to be lower than the patch cutoff, so you do NOT need FIX95CPU (another is that running in ring 1 avoids the problem altogether). Since Virtual PC 7 requires hardware virtualization, perhaps having the raw code in the correct ring 0 position with a faster speed makes the IOS protection error occur. This is a problem in VMWare as well, but I believe that the program has the option to turn off hardware virtualization, thus avoiding the error. I am going to try to current patch in VMWare Workstation, and I will e-mail them if it works. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=817
