ttrainor - thanks.
I've done the uname -r and I got "2.4.20-8" as a response, so I see where I have the wrong RPM.
Now you mentioned an upgraded, athlon optimized kernel. Would that be something I would achieve by applying all the RPMs on that Stanford website you send? There are quite a few RPMs available there.
It seems the alternative is to download the tar.gz file from the nVidia site. I'm sure I can download it, I'm certain I can burn it onto a CD... but what then? Is it as easy as a double click? Should I do an "rpm -d NVIDIA_nforce-1.0-0261.rh90up_2.4.20_6.athlon.rpm" ? (I think it's -d to delete an RPM...?)
Would it just be easier to upgrade to 2.4.20_9 since there's an nVidia provided driver for that? (I'm assuming that'd just be a download from the RH site?)
Thanks again for your help, I'm sure this is simple stuff for quite a few people out there, but I sure am struggling!
