NVIDIA Driver - Convert from Desktop to Mobile (Laptop)

Hey, I'm a bit confused as to what you are asking in step 6. I found my hardware ID's:

PCI\VEN_8086&DEV_27A2&SUBSYS_81E6104D&REV_03
PCI\VEN_8086&DEV_27A2&SUBSYS_81E6104D
PCI\VEN_8086&DEV_27A2&CC_030000
PCI\VEN_8086&DEV_27A2&CC_0300

Not sure what to do after this. This is what I have in the String section of the .inf file:


[Strings]
; Non-Localizable Strings
REG_SZ = 0x00000000
REG_MULTI_SZ = 0x00010000
REG_EXPAND_SZ = 0x00020000
REG_BINARY = 0x00000001
REG_DWORD = 0x00010001
REG_SZ_APPEND = 0x00010008

; Localizable Strings
NVIDIA = "NVIDIA"
NVIDIA_G84.DEV_0407.1 = "NVIDIA GeForce 8600M GT"
NVIDIA_G84.DEV_0407.2 = "NVIDIA GeForce 8600M GT "
NVIDIA_G84.DEV_0409.1 = "NVIDIA GeForce 8700M GT"
NVIDIA_G84.DEV_0409.2 = "NVIDIA GeForce 8700M GT "
NVIDIA_G92.DEV_060C.1 = "NVIDIA GeForce 8800M GTX"
NVIDIA_G92.DEV_060C.2 = "NVIDIA GeForce 8800M GTX "
NVIDIA_G92.DEV_060B.1 = "NVIDIA GeForce 9800M GT"
NVIDIA_G92.DEV_060B.2 = "NVIDIA GeForce 9800M GT "
NVUninstall.desc = "NVIDIA Display Driver"
DiskID1 = "NVIDIA Windows Vista Driver Library Installation Disk 1"
NVSVC.name = "NVIDIA Display Driver Service"
NVSVC.desc = "Provides system and desktop level support to the NVIDIA display driver"

Thank you.

Hello Marko8, and welcome to Windows Seven Forums! Torrentg is unavailable, and even though I am not the video driver Guru he is, I will try to help out.

The objective is to take a "desktop" video driver and alter it so it will work for a mobile device, ie laptop. The list shown above is the Nvidia video cards supported by this driver package. We need to know what Nvidia hardware your laptop is using. The first step would be for you to fill in your computer specs in your user "control panel" of the forum so we can nail down what is in your mobile device.

When I Googled your device ID: PCI\VEN_8086&DEV_27A2&SUBSYS_81E6104D&REV_03

I get a Sony Viao with a GeForce Go 7400 or 7700?

DriverPacks.net Forum / Let's do the HDA-Thingy!

GeForce Go 7400 disappeared from device manager

If so, you are trying to mod drivers for 8000. The tutorial instructions say get the driver closest to your card so I would think you need to be moding drivers for the 7000 Nvidia chipset?

Please verify this information before we proceed.

Cheers!
Robert

Ok I filled in what I could for computer specs.

Excellent!

Now, step one is to download the latest Nvidia driver pack for the 7000 series cards.

Then when you get to step

6) In the .inf, scroll to the bottom [Strings] section. Again, look for most similar desktop model. Change the beginning part to match what you found in last step 5. For example:

NVIDIA_DEV.0421.01 = "NVIDIA GeForce 7400 GT"

and you have 7400M GT, change it to

NVIDIA_DEV.0426.01 = "NVIDIA GeForce 7400M GT"

OR what ever you find closest to work with.

Then continue to adapt the steps of the tutorial to your 7400 Nvidia chip and let us know how it goes?

Cheers!

Ok it seems I'm getting slightly closer. In Device Manager under Display Adapters, it shows NVIDIA GeForce Go 7400 however, under details I get: "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)".
Now when i try running the installation, this time it actually goes through instead of giving me an error but, the installation never completes and asks me to try at a later time. Now once again I have hit a dead end and I'm not sure what to do.

The driver package is for a desktop computer, not a laptop, so it is not likely it will install. However, since the INF file as been modified to work with a mobile device, we should be able to manually install it.

You should have your Nvidia driver package in a folder on your C drive:



Open Device Manager (type it in the search box, for example)
Select the Properties for the Nvidia device:



Select to "Update Driver":



Select to "Browse":



and browse to the C drive, the Nvidia folder with the INF you modified:



This should install the modified driver for your laptop.

If there is a problem, open the INF file and post the changes you made so we can analyze it.

Cheers!
Robert

Here are the .inf original files and changes:

As well as my hardware IDs:
PCI\VEN_8086&DEV_27A2&SUBSYS_81E6104D&REV_03
PCI\VEN_8086&DEV_27A2&SUBSYS_81E6104D
PCI\VEN_8086&DEV_27A2&CC_030000
PCI\VEN_8086&DEV_27A2&CC_0300

Marko8, did you try the GeForce Go 7000 Notebook drivers from Nvidia?



Are you using the 32 bit Windows 7 or the 64 bit?

I've tried the NVIDIA driver that your taking about but I haven't tried modifying it manually. I have been modifying the driver that my computer downloaded automatically for me. I guess I can give the other one a try. But was what i sent you correct? Did I modify the .inf files properly? And I am using 32bit.

Well ... I will have to take some time to check it out, but I do not think drivers for the 8000 series will work for a GeForce Go 7400?

The driver package available from Nvidia for the GeForce Go 7000 is already modded for a mobile device. Please, what did not work for you. Did you try to install the INF manually for your 7400? Or did the Installer fail?

I will have to do some research and get back with you tomorrow.

Cheers!
