9.1 Where to get the driver
You can either download them from www.ati.com
(and in that case follow the RedHat guide), or use RPMDrake/urpmi to get them. Note that you can only get the drivers via urpmi if you are a paying Mandrake Club Member.
9.2 Steps to take before installing the drivers
The only step to take before the installation is to make sure you have the kernel sources installed. You can get them by using RPMDrake.
9.3 Installing the drivers
Use RPMDrake to download the drivers. They will get configured automatically. You only have to run fglrxconfig to configure X Windows.
