New to PCLOS w\ATI X800GTO......needs help

[Pagan Wizard]

See my sig for system details. I just installed PCLinuxOS on a USB HDD. I also have WinXP on an IDE HDD, everything works flawlessly, but I cannot get drivers to work for my video card in Linux. For now, I am stuck with 800 X 600. I should also add that this is my first time trying Linux, and I know nothing about it. I tried asking about this on the ATI pages, but couldn't find the help I needed there.

Here is the link to PCLinuxOS if you don't already have it and would like to check it out for yourself. http://pclinuxos.com/news.php
