i put together a post on my blog including a link to my full double driver backup.
the touch screen driver is included, however i believe there is some sort of missing calibration tool from the vendor that is missing. if anyone can help post here!
i have the audio drivers backed up, but i myself can not get the touch screen to work even with the backed up drivers. i suspect there is some kind of utility that goes along with it. i will try and post it later.
