Need Settings Instructions for RealTek AC97 Audio Configuration and AVRack

where can I find instructions in the use of the settings for AC97 Audio Configuration screens. What they mean and how/why I should set them.
Also a guide to the buttons on the AVRack recording screens would be good.

I am a complete novice at this using pc's and music together although I do know my way around computers and the internet. I have managed to get my tape cassette deck recording to the pc without any noises or problems using the AC97 but I am stumbling about a bit with the configuration settings.

Is there somewhere I can see a tutorial ?. cannot find any readme or online information anywhere.

thank you for any help you can give me ..
