The default drivers that comes with the C204tmi made the users very happy, especially if they want to play Source Engine games (HL2/CS Source). After you start up the game a beautiful blue screen of death appear followed by a system reboot. To solve this you have to install the latest nvidia official drivers, but since the official drivers don't have support for our tablet pc neither geforce go cards, we have to make some modifications in the setup config file to make them work. Here are the steps: 1. Download the official drivers from Nvidia download page (81.98) 2. Try to install, It will fail, but at least they are extracted in the C:\NVIDIA folder. 3. Enter in this folder and find the file nv4_disp.inf , open to edit it (Notepad). 4. Add a line in the [NVIDIA.Mfg] section: Code: %NVIDIA_NV44.DEV_0167.2% = nv4_NV3x, PCI\VEN_10DE&DEV_0167&SUBSYS_007B1025 5. Add a line in the [nv_SoftwareDeviceSettings]: Code: HKR,, NvCplEnableRotatePage, %REG_DWORD%, 1 6. Change the line in the [nv_SoftwareDeviceSettings], from: Code: HKR,, RotateFlag, %REG_DWORD%, 4 to: Code: HKR,, RotateFlag, %REG_DWORD%, 16 7. Add the line in ;Localizable Strings : Code: NVIDIA_NV44.DEV_0167.2 = "NVIDIA GeForce Go 6200" 8. Save the file and run the setup.exe Now we can play Source! Have fun!
