I am currently running 10.2.8 You will need to have a DVD drive to install from the Tiger installation DVD. If you have a FireWire box with a DVD drive in it, you could use it as the startup drive and do the installation. If not, you might be willing to spend the extra $29 or so to exchange your DVD for a set of CD installation discs from Apple and do it that way.
