HOw would they do that? Do you think that they have the windows driver source code they can look at and fugure out what is going on? If they did, development of drivers would be trivial. They also have no idea how to get the information. It would really really really help if the manufacturers gave infomation.

Each incarnation can totally change the registers, their content and the meaning of their content. ------------------------------------------------------------------------- Using Tomcat but need to do more?
