it should have come with a utility to build and format a backing store file. last time i used it (1.0) it was called VPC HD util or something like that. the options menu that specifies which disks will be mounted to which VMs should launch it as well.
See, I am trying to install Windows on it. Do I have to install DOS first? Whenever I insert the Windows 3.1 disk 1 and start the comp, it gives me a non-system disk error. I have no idea how to do this... :lol
