Actually, installing a bootable copy of 9 into X is pretty easy. You don't have to install 9 first. The problem is that Apple doesn't make it easy. This is understandable, as they want to wean people into using OS X, and rely upon Classic to run any older programs. You really just need to take the OS 9 System Folder, and drop it on to your OS X bootable disk. The Classic controls and the Startup Disk preference pane both look for it in this location. So (Since OS 9 discs are bootable), just pop in the disc, and copy the System Folder straight to your OS X installed hard drive. Don't worry about the OS X folder called "System", as the system has come to expect both "System" and "System Folder" on the same drive.
