sax2 problem

How do I get more than 8 bit resolution? And how do I save the info I but in sax2? It seems that it is not able to save to the XF86Config file, it is not that I am unable to write in the code, but it should work. Also Can someone give me the correct name and spec of my video card I have a Powerbook (bronze) G3 400 (no firewire, but I have DVD) I think it is ATI rage (something) 8 Mb ram that should be able to run 32 but. I have been looked around at the Apple site, and it is informative as always. I have concluded that they only give their writers a picture of the product, then ask them to write the technical spec's.
