First off, i would recommend downloading files for linux from within linux.
You need to look for files with the following extensions:
the tar.gz and .gz files are linux zip files.
for the .tar.gz files type man tar
and read how to untar files.
for the .gz files type man gz
(not sure which one)
the .rpm files (which stands for Redhat Package Manager)
can be done from redhat with a nice gui'd program,
just look for it in the menus.
Also be sure to always read the readme files that come with
the drivers. Hope this helps you a bit
