X configuration ordeal

["Claire Marshall" <claire marshall mailcity com>]

The first time I installed RH 5.1 a couple of months ago, installation was a breeze. I was able to configure  and run X at 800x600 at 75 Hz which was pleaseant.
After messing up my system trying to configure LILO, I re-installed RH 5.1. I lost the ability to use my soundcard along with the ability to run X at a decent resolution. At present I can only run X at 800x600 and the flickering is giving me strong headaches!. To make matters even worse, I am in "scrolling mode" meaning that my screen is too large. When I first installed RH 5.1 I was able to run X at 1024x768 at a very pleasent resolution along my 800x600 default.

Can anyone help me achieve my goal of running X at 
800x600 (16 bit colour) at 85 Hz  as a default WITH the option of having 1024x768 (16 bit colour) at 85Hz???. Moreover, I want to say goodbye to "scrolling mode"!.

NOTE: I don't know whether this is relevant but I am able to use 1024x768 85 Hz 24 bit colour in Win95.
And that's a very nice and comfy resolution.
