Custom fabrication project: Extract and install Win7 drivers btwn PCs?
I'm sure you all agree one of the toughest parts of finding an answer online is to find the right forums to ask the question. After much thinking, asking, and researching, I figure your forum is the right place for my questions.
Foreword: Constructive comments are welcome, but "can't be done" or "I think so" or posts like that are unwelcome. Respectfully, answer if you actually know what you're talking about. Thank you.
I am planning to build a fully functional Windows 7 PC in my vehicle complete with wifi, cell phone internet, and enough power to do anything entertainment-related. The PC itself is easy to build, but the display is why i come to you today. I want a touchscreen display mounted in my vehicle's dash to eliminate any keyboards etc...
I've looked EVERYWHERE for a touchscreen display of decent size, contrast, brightness, and sensitivity to use for my primary display, but i have found ZERO candidates. So the easiest way for me to get a beautiful, HD, multi-touch display is to rip one out of a tablet.
After much thought, I have decided to use the display and touch digitizer from an Acer Iconia W500. This display has multi-touch, HD res, and a beautiful look. Furthermore, documentation from the popular website TechRupublic (and others) have shown that the LCD controller and touch controller are SEPARATE from the tablet's motherboard... this is good news because I have already found the necessary parts to make the LCD a "DVI-output monitor" and the touchscreen a "USB-output digitizer". What does this all mean? It seems I have all the HARDWARE to make the Acer tablet screen usable as a multi-touch monitor for any regular computer.
I need some help with drivers. I need someone of decent intelligence to comment on my method for monitor recognition. Since the Acer tablet runs Windows 7 Home Premium 32-bit, I figured it would be possible to find the drivers in the tablet's OS and extract them for installation in my car PC's OS.
If you go into Windows 7's Device Manager, you can navigate to the monitor and touchscreen. Then if you click on Drivers and then Driver Details, you can see the exact name and location of the drivers in the windows filesystem. At that point, you can go to
and find the exact driver labelled as "example.inf_loc". If someone were to extract that .inf_loc file and rename it as .inf, then technically they could install that driver onto a Windows 7 car PC. So hopefully I could use the above process to locate the TABLET TOUCH AND LCD DRIVERS to install them into the CAR PC FILESYSTEM. If everything works as planned, then I should have a car computer using the exact drivers from the Acer tablet to power the multi-touch display.
What does everyone think of this? Personally, I feel like i've created a viable solution for myself. All I need is to mess around with a W500 tablet to find the drivers, at which point I could copy the drivers and voila!
Are there any holes in my reasoning? Any oversights? Remember, everyone, I want POSSIBLE. If I wanted things to be easy then I'd have settled for a crappy touchscreen a long time ago. Even a touchscreen notebook isn't as nice as my tablet idea. I'm willing to make this a project, and more and more I think it is doable. Any advice on this project is much appreciated. Just ask me for any clarifications. I'll leave some info about the A500 tablet below.... it IS A DIFFERENT TABLET because it's running Android and the Tegra 2 processor, but the W500 should really only differ in the C-50 processor and Windows 7 OS.
