rhl-ig-x86(EN)-9-HTML-RHI (2003-01-16T18:24-0400) rhl-ig-x86-en-9/s1-trouble-after.html#S2-TROUBLE-NVIDIA refers to an old version of the nvidia driver. You should probably not link to any version specifically A word a two about why you aren't bundling the drivers would probably be good too otherwise people are going to wonder why the installer didn't do the job for them.

Thanks for the feedback. This is a great suggestion. I have changed the URL so that it points to the driver archive, rather than a specific driver. The correction will be made available in future revisions of the documentation. Cheers!
