HOW TO MOD WINDOWS INF FILES - INSTALL DRIVERS FOR UNSUPPORTED HARDWARE - Sony Vaio VGN-SZ3HP - Nvidia GeForce Go 7400 Windows 7 64bit

### HOW TO MOD WINDOWS INF FILES - INSTALL DRIVERS FOR UNSUPPORTED HARDWARE ###

Example: Install Nvidia GeForce Go 7400 Windows 7 64bit driver on 2006 Sony Vaio VGN-SZ3HP

- Windows 7 -> Device Manager -> VGA-Adapter -> Details -> Hardware-IDs:
  PCI\VEN_10DE&DEV_01D8&SUBSYS_81E6104D&REF_A1
  device id = DEV_01D8            = the device (Nvidia GeForce Go 7400)
  subsystem id = SUBSYS_81E6104   = more or less the oem specification, e.g. for the sony vaio
  If the subsystem id does not match, windows won't install the driver.

- Download original driver
  https://www.nvidia.de/Download/driverResults.aspx/9026/de

- Extract 179.48_notebook_winvista_win7_64bit_beta.exe
  In my case it contains a folder "Display"

- There are multiple .inf files which contain important information
 
- Search through the .inf files for your device id, and idealy for the subsystem id.
  I used    grep "DEV_01D8" *   on Ubuntu linux for that.
  The inf files are name-coded after the vendor. E.g. the correct file for my Sony was

- Open e.g. "nvsm.inf" in text editor
  Search for the device id.
  Example:
     %NVIDIA_G72.DEV_01D8.2%  = nv_G72,    PCI\VEN_10DE&DEV_01D8&SUBSYS_C026144D
  Replace the SUBSYS id of the first match with your SUBSYS id
  Example: replace "SUBSYS_C026144D" with "SUBSYS_81E6104D"

  Additionally I had to change the windows version from Vista to Windows 7
  Replaced "NTamd64.6.0" (Vista) with "NTamd64.6.1" (Windows7)
  https://docs.microsoft.com/en-us/windows-hardware/drivers/install/inf-manufacturer-section

- To limit the number of available driver options, I deleted all other .inf files

- Finally got to the device manager and install the driver by disk method
  Windows 7 -> Device Manager -> VGA-Adapter -> Install driver -> Manual -> by disk -> select modded .inf file

 


### ADDITIONAL NOTES FROM RECHERCHE

 

NVIDIA_G72.DEV_01D8.1 = "NVIDIA GeForce Go 7400"
DEV_01D8
NVSZ.INF
From windows device manager: PCI\VEN_10DE&DEV_01D8&SUBSYS_81E6104D&REF_A1

NTamd64.6.1 = Windows7
