Using this info having looked at the following segments of the NVAM.INF file, for the closest matches The folder is named as such as these are the latest drivers for my card namely GeForce 8600M GT Ĭard information and type is found in HardwareDeviceID under Windows Device Manager ĭEV_0407&SUBSYS_9016104D “NVIDIA GeForce 8600M GT”
Using your guide, unpack the driver files, back up a copy of the NVAM.INF file found in the unpacked folder Ģ66.58_notebook_winvista_win7_32bit_international_whql\Display.Driver I have additions specifically for the SONY VAIO VGN-AR61ZU which sorely needed an update due to games like WoW and Rift gfx changes. This is an old thread a but a good resource for people needing to update their mobile gfx drivers due to an ‘inability’ by the manufacturers of the laptop to just do the paperwork…so cheers for starting this topic. Then run setup.exe or install the driver manually. If you look in the INF file it will be quite obvious how to proceed. In my example the lines I am adding looks like: NVIDIA_DEV.0426.01 = "NVIDIA GeForce 8400M GT (Sony Vaio FZ38M)" %NVIDIA_DEV.0426.01% = Section012, PCI\VEN_10DE&DEV_0426&SUBSYS_9005104D Note that the “0426” part in the beginning of the first and second line is derived from “DEV_0426” part in the hardwareID which is unique depending on what graphics card it is. Then I opened nvam.inf and added the below two lines where there are similar rows in the INF file. Then I went to C:\NVIDIA\DisplayDriver\186.03\International\Display (the path might differ when using a newer driver) which is where the files are unpacked when you run the downloaded driver. In my case I looked up the hardware ID for my Nvidia GeForce 8400M GT in device manager and found out that is has the hardware ID “PCI\VEN_10DE&DEV_0426&SUBSYS_9005104D”.
May I mention that this solution is not support in any way, but the important thing is that it works. The solution to install the Nvidia driver anyway is to download and unpack the driver from and then modify one of the INF files to make it support your video card. If you did not already know it Nvidia offers drivers for many of its mobile graphics chipsets on but unfortunately these drivers do specifically not work on SonyVAIO machines. In all releases of Windows 7 up to RTM there has been a driver available via Windows Update for the Nvidia mobile card but this driver seems to be pulled from Windows Update (and Microsoft Update Catalog). The problem is that drivers for the video card for Nvidia mobile graphics chipsets is missing which means running with the feature lacking and slow Standard VGA driver. When I installed Windows 7 RTM on my Sony VAIO laptop I discovered the same problem as when beta testing WindowsVista some years ago.
