Not what oscdimg is supposed to do. I did the following,
1. Download any of the above versions
2. Open the ISO file with UltraISO
3. Delete ie.cfg from \source\ folder
4. Save ISO
5. Burn with your favourite ISO burning program
When you install, you'll prompted for which version you wish to install.
Then select option to activate later on the serial number screen
Either use your own key or daz loader or which ever hack you want to
