    No. You can have earlier versions of the OS installed. (Or no OS installed: Snow Leopard will do a full, "clean" install.)

    Following are the steps I took to upgrade from OS 10.4.11 (Tiger) to Snow Leopard. (Some people install Snow Leopard directly on top of their old OS. I prefer to use the following method.)

    1) Do a clean install of Snow Leopard to a new partition. If necessary, clone your old OS partition to a temporary, bootable external hard drive.

    2) All Snow Leopard disks can do a "Clean Install". But with the $29 disk you need to follow some extra steps, since "Erase and Install" is not part of the automatic installation... but the tools to do so are provided on the DVD.

    Basically, when you put the Snow Leopard DVD into your Mac, you will be presented with two options: 1) to "Continue" with a standard upgrade, or, 2) go to "Utilities". Select the "Utilities" button (there will be a reboot in order to run from the DVD). In the new screen that appears, under the "Utilities" menu, select Disk Utilities to format your hard drive (or partition) that Snow Leopard is going on to. When you have finished formatting, QUIT from Disk Utilities, and the installer will then complete the installation of Snow Leopard. (Note: be prepared to wait several minutes when the system reboots during installation as it copies and sets up all the files.)

    3) At some point during the installation, the installer will search all other partitions for an older OS, and if found, the installer will ask if you want to import the OS Settings, Files and/or Applications from that partition. Do this for a very smooth transition.

    4) All my apps from OS 10.4 continued to work in Snow Leopard, but some of my printer drivers and scanner utility needed upgrades. Until I could find the upgrades, I was still able to Start Up from my OS 10.4 partition (press Option during start up) in order to use my printers and scanner in the meantime.
