Obtain the Fedora Core 6 cd images or DVD image from a Fedora mirror (or use the torrent) and burn to CD's or DVD. If you select Fedora Extras, this will give access to MANY more applications than included on the CD's or DVD.(For more information on how to download Fedora Core CD's or DVD). However this requires a high-speed internet access that is detected by the Fedora Installer.I am assuming you are using Fedora 8, so just click on the link on the Livna page for instructions on how to get our driver.You may have to ramble around the site a little to find what you are looking for.
There used to be some advantage in terms of certain files not getting crapped on by the n Vidia install action too, not sure if that is still true.
Fedora Core 6 is the first Fedora distribution that allows you to add repositories other than the official Fedora ones at installation time (if you have read the installation notes you might have noticed something about that).
However, if you installed with only the default ones, It is easy to add repositories after installation. Go the the FAQ page and proceed from there: Lots of these packages include proprietary (binary) video (and other) drivers that Fedora will not include in their distribution (it's policy).
Livna maintains a repository of packages that lots of Fedora Core installers use to get "better" video and/or wireless drivers and certain other programs.
The recommended update mechanism for Fedora (since about Core 3 or 4) is yum, and there are various sources that tell you how to add the livna repositories to the places that yum will use to obtain (and keep current) whatever things you are interested in.
