Problems with Graphics Card -- Ati Radeon

[SniperVishal]

Hi, I just finished installing a Fedora Core 4 distribution on my computer. The problem is that I was unable to install it in graphical mode, so I had to go for the text mode installation. Now I am able to boot into Linux from the root, the system loads with a screen that is covered with thin and vertically aligned white, green and yellow stripes, with an inch by inch square box instead of the mouse pointer).

I have a pentium 4 with an ATI Radeon 200 (RC410) graphics card. I read some articles and found out that the problem is with the drivers of the graphics cards. where can i download the drivers and how can i setup it from root without startx?

Any help will be appreciated..
Thanks,
Vishal
