Compaq Presrio CQ50-215nr Windows XP driver

Please read the instruction carefully before installing the drivers. Install according to the order given. Install patch below because windows installer needed for Intel wireless and netframework needed for HP Quicklaunch Button Installation.
I try my best to find a direct file installation for conextant audio but still not available. Maybe the original file was no longer available on internet.
