Hi.
RedHat 9 doesn't come with drivers for the fx5200.
The first thing you'll need to do is get into 'single user mode'
When GRUB loads (and you get a list of the available operating systems to boot) highlight redhat and hit 'e'. This allows you to edit the kernel commands. Add the word 'single' (no quotes) and then boot.
You'll then have to download the drivers from the nvidia site, and install them (the drivers come as a file called NVIDIA-Linux-x86-1.0-4496-pkg2.run)
They're at
http://www.nvidia.com/object/linux_d..._1.0-4496.html
Hope this makes sense.
Dave
P.S. The readme for the drivers is at
ftp://download.nvidia.com/XFree86/Li...496/README.txt
You'll have to read this to configure the XF86Config file.
