Corona688,
Thanks for the useful info. I'm researching my system' drivers now. It is interesting!
When I mentioned Windows, I had in mind a different chain
. In Windows from device manager you can clearly identify all hardware and follow the chain to a driver, its resources etc. Apparently Windows uses a different design. The point is, that in windows it's all very visual, so it is easy to follow, even if its internal design is flowed. It is amazing how much I learned about system at this point!
