I just checked my "universal install disk for most systems" for Tiger and verified that there was only ONE DVD disk in the box for installing the OS. Maybe you are referring to the CD version of the OS installation of Tiger? If so, you should make this information more clear. The CD version was not universally available in retail stores. Anybody needing the CD version because of their lack of a DVD drive in their Mac had to first purchase the DVD version and then return it to Apple and pay extra to get the multiple disk CD version set.
