Microsoft PixelSense (formerly called Microsoft Surface) is an interactive surface computing platform that allows one or more people to use and touch real-world objects, and share digital content at the same time. The PixelSense platform consists of software and hardware products that combine vision based multitouch PC hardware, 360-degree multiuser application design, and Windows software to create a natural user interface (NUI).
I have gotten my hands on a unit with a defective hard drive. In the process of reviving it, I learned a lot, but I also found out that resources and related web pages are slowly disappearing. Therefore I decided to write down my notes so at least some knowledge of these big machines stays preserved.
Put the calibration data into the registry: Copy the files from TableParameters to %PROGRAMDATA% and run Calibration.reg.
Microsoft does not support this unit any more. The support phone number is answered by a robot putting you on hold, and is disconnected after 5 minutes. Chat support does not work, since you'll get connected to the Microsoft Surface tablet support department. Renaming a product is a horrible decision.
The P5LD2-VM motherboard is made by Asus, but Microsoft provides a custom ROM. Installing a generic ROM for this motherboard is discouraged and will likely not work (as stated by an Asus support employee).
The edges of the Surface glow in different colors: Purple means starting up, Blue means shutting down and cooling down, Yellow and Red mean that something is wrong, most likely some cable isn't properly connected. Check especially the 5 LAN cables that go from the IR cameras into the Microsoft Hydravision pci card.
