I've followed instructions from two different helpful threads to set up a Virtual Machine that has an MS-DOS 6.22 environment. I'm using a trial version of Parallels desktop 6 for MAC. I found threads telling me how to set up the environment, create a virtual hard disk, format it to be bootable. I've done all that successfully. I'm stuck, however, on getting files from the MAC environment into this virtual machine. I read several threads about renaming the *.hdd file to a *.dmg file, and then using Finder to copy the files to it. I've tried that. When I double click on the renamed file, I receive this error message: THE FOLLOWING DISK IMAGES COULDN'T BE OPENED. DOS_VM-0.dmg (Reason: not recognized). I also tried connecting the VM CD-ROM virtual drive to a disk image of the folder that contains the files that I wish to copy to the virtual hard drive. The VM boot messages tell me that the CD-ROM virtual drive is letter "R". I can change to drive "R", but when I execute the DIR command, I receive this error: CDR103: CROM not High Sierra or ISO-9660 format reading drive R Abort, Retry Fail? The files that I want to copy are a Clipper application executable, and its associated dbf and ntx files. If I can get this to work, I will buy a copy of Parallels desktop. Thanks for any help you can provide.
