Hello everyone, i have been trying to follow the guide (I have a HP nx9420) with an ATI mobility x1600. Trying to trick it into think it is just a regular ati card. I have gotten stuck @ step 3. I modded the drivers of the one i downloaded but i don't know how to install them through the control panel I can't see a way to do that. Every i uninstall my old driver and wipe clean of it and restart, the computer automatically reinstalls the driver so it is a mobility card again. I don't know what to do at this stage to unlock the card. I appreciate all the help!
