First, your best bet is to read and understand the 3d driver associated with whatever hardware you're looking at. Most of the questions you are asking can be most easily answered by examination of the code. Second, it is easiest to answer your questions if you refer to specific lines in specific files. There is no variable called "AGP Offset" anywhere in the drm. Maybe there are some with similar names, but I can't tell which one you're talking about. Thirdly, nobody's got the time or patience to explain the entire workings of the drm to you. Make an honest attempt to read and understand the code. Ask a few questions and you'll get a few answers. Ask a thousand questions and you will be lucky to get any at all. Keith _________________________________________________________ Do You Yahoo!?
