A. After a successful installation, all you need to do to mount an ISO image is right click on the ISO image file and select the option 'mount image' from the context menu, the image should then show up as a CD in 'My Computer', from there just treat it like any other CD. To remove the image, just right click on the mounted image CD in 'My Computer' and select Eject from the menu.
A. Due to major enhancements and changes in Mac OS X 10.2, it is far better to use this OS or a newer version over previous version of OS X, also making it backward compatible with 10 and 10.1 was just too time consuming. As for OS 9, it is our intention to concentrate on OS X only. Therefore unfortunately it will not be available for systems below 10.2. Sorry.
