How to: modify NVIDIA drivers for VAIO

Guys,

I'm really interested in finding out how to modify NVIDIA drivers to be usable on a VAIO?

Which inf file has to be edited (nvszf.inf I believe...?) and how?

The modified drivers need to:

1. Be installable on a Vaio machine (which the original aren't)
2. Allow auto dimming of the brightness of the screen!

I know some of you have been so kind to do that in the past. In my case ver. 266.58 is now due and I would like to learn what needs to be modified in general.

I think a small instruction will be highly appreciated by everyone here!

Thank you in advance!

 

what is your nvidia card is?give the id from device manager..

 

Where do I find that ID... Under device properties I find several Hardware IDs...!?

 

do to device manager\display adapters\nvidia\properties\details\hardware ids

then copy all.

 

It is an Nvidia 310M

PCI\VEN_10DE&DEV_0A75&SUBSYS_9069104D&REV_A2
PCI\VEN_10DE&DEV_0A75&SUBSYS_9069104D
PCI\VEN_10DE&DEV_0A75&CC_030000
PCI\VEN_10DE&DEV_0A75&CC_0300

 

hi there try this inf for nvidia 266.58 64bit

 

Thank you very much!! Would it support auto-dimming!?

 

yes i think so,did you try it??

 

No, wanted to ask first. As far as I know something additionally has to be added/edited in order for that to be possible. I had installed older drivers that were modified - they installed successfully but auto-dimming did not work.

Does anyone have a clue?

Will try it soon and let you know.

 

I remember making a modded inf for Vaio S. I will post the instructions later.

 

Exactly you You were one of the neat guys to modify a driver Didn't know you were still around!

Would be great if you can create a small manual.
My main concern and question is what needs to be modified in order for the driver to allow auto brightness dimming....

Haven't yet tried the one samozen, if anyone already has - please share how it works?

 

I will make a modded inf and post the instructions by tomorrow.

 

Thanks in advance Rajesh!!

 

Here is the attached modded inf. Download the 64-bit Nvidia verde notebook driver, extract it using 7-zip or Uniextract.

Copy and replace the attached "nvszc" inf in the "Display.Driver" folder in the extracted driver package. Make a copy of the original "nvszc" inf, so that you will know what had changed in the modded inf.

I will post the instructions to mod later. Try the modded inf and let me know how it goes.

The modded inf contains Sony specific settings from the latest 197.91 driver supplied by Sony.

Uninstall the existing GPU driver before trying this driver. Choose "Custom Install" at the set up screen, and check the option "Perform Clean install".

 

Installs and works perfectly!! Auto-dimming works as well! Thank you very much once again! +1rep!!

You are very helpful!

 

You are welcome.

Do you have any delay when logging off?

I get a log off notification (waiting for background processes to close) with this driver in my FZ. The process NvXDSync.exe might be responsible for this delay.

 

Hmm, will keep an eye on that. Didn't notice anything when restarting... Or only when logging off?

 

The notification comes up during Restart/ Shut down/ Log off (all involve logging off), but not everytime, only sometimes.

Edit: Gracy123, I forgot to add an existing "entry" in the inf, so re-uploaded the inf. This shouldn't affect your install.

 

Ok, will keep an eye on that and let you know if I notice a delay.

Are you sure I don't need to reinstall? So far no issues.

 

Gracy123, You don't need to reinstall the driver.

 

Roger that.

Thanks once again!

 

You can get the attached instructions for modding the Nvidia driver INF. Questions are welcome.

 

Awesome!! Thanks a lot on behalf of everyone here!!!

I will have to study it and will let you know if any questions come up

Thanks once again!!

 

I just made a modified nvszc.inf for my vaio CW2S1E (VPCCW2S1E) if anyone wants/needs. its for DEV 0A2B SUBSYS 9072104D. the nv_miscBase_addreg's were taken from the original official 188.67 driver from sony's website, aswell as the nv_commonDisplayModes_addreg. As there were no nv_timingRestrictions_addreg's in the original, i got these from laptopvideo2go's modified 197.01 which has added compatibility for the 9072104D subsys along with others. anyway the rest is 266.58, so just download that from nvidia and copy over the inf if you want to use this. brightness buttons working fine, all games working on my windows 7 home premium SP1 machine.

windows vista 64 bit (section041) and windows 7 64 bit (section042) should both work.

 

I'm looking for specific modded inf files for my Vaio VGN-SZ650N.

At the moment im running the latest NVidia 275.33 (32bit) drivers with the modded inf files from laptopvideo2go and i keep getting crashes (no bluescreens, only restarts graphic driver) while watching videos online (youtube for example). But this seems to be happening only while using my docking-station/external monitor.

nevertheless i would appreciate it, if someone (maybe coolguy?) could provide me the needed files for the drivers mentioned above. Both, 32 and 64bit version would be cool though.

Hardware-ID
PCI\VEN_10DE&DEV_0427&SUBSYS_9008104D&REV_A1
PCI\VEN_10DE&DEV_0427&SUBSYS_9008104D
PCI\VEN_10DE&DEV_0427&CC_030000
PCI\VEN_10DE&DEV_0427&CC_0300

Maybe i can get rid of the crashes with the right modded inf files for my Vaio.

Thanks in advance!

 

Try the attached INF. Download the notebook 32-bit 275.33 driver from Nvidia and replace the attached INF in the "Display.driver" folder, run the setup.

 

hi coolguy i have a vaio vgn-cs21s with a nvidia 9300m gs running win 7 64
i tried following your guide on the 280.26 verde drivers but didn't make it
could you be so kind to create a modded inf to get brightness control enabled?

 

Try the latest driver from laptopvideo2go. If that driver gives problems, I can make you one.

 

I tried them this morning,despite the fn brightness keys do not work the strange thing is that even from the windows mobile control panel i do not any brightness control at all,it disappeared,no option at all
on second hand the brightness is set to its maximum and there is no way to lower it
the installation bytheway went fine without given any errors,i don't get how brightness control can suddenly disappear,my gpu is listed as supported

the only driver provided by vaio for my vgn-cs21s are the forceware 186.40 win 64 as stated by gpu-z,hope this can help ( http://support.vaio.sony.eu/computi...0208301.exe&m=VGN-CS21S_R&ip=EP0000208301.htm)

 

this should be the configuration file of the setup

 

Could you clarify what you are doing?

e.g. your VGN came with Vista preinstalled and you are doing a clean install of Windows 7 and the brightness control is not working.

 

i did a clean install of win7 and the vaio driver works fine.
unfortunately it's a very old driver and i wanted to install the newest one to get dxva on photoshop,adobe flash etc since my sister uses these programs.

when i install the latest with the modded .inf of laptopvideo2go i do not have any brightness control at all,nor through the windows mobile control panel or through the fn keyboard keys,so i was wondering how to have brightness control enabled
moreover the brightness is fixed to the maximum

 

Try the drivers in this thread:
http://forum.notebookreview.com/sony/342947-my-discoveries-vaio-z-s-hybrid-graphics.html

Remember - yours is a VGN, so don't go for the VPCZ1 drivers.

 

He doesn't have a Z, but a CS laptop.

 

Could you post the hardware details of your GPU from device manager (only the first line). - not needed.

Edit: Just saw your prev. post. I will make a modded inf for you.

 

That would be very kind of you!Thank you

 

Copy and replace the "nvszq" inf from the attached zip file in the Display.driver folder of the 280.26 Win 7 64-bit notebook driver. This modded inf only supports Windows 7 64-bit and has all the OEM GPU settings preserved.

 

rhanx gonna give a try now!

 

works perfect!fantastic work coolguy!

 

Will that modded 280 inf work with a vaio VGN-AW310J? I have the Geforce 9600M-GT card. Tried updating with the modded infs provided by laptopvideo2go and I just keep getting BSODs when I start. It seems to install alright, just can't avoid the BSOD. Running Windows 7-64bit

Edit: The BSOD always shows up right after start up and always involves nvlddmkm.sys

Thanks

 

Get the driver from the guide in my signature.

 

hi ,
i'm using VPCZ115GG
Display is GT-330M
HARDWARE ID: PCI\VEN_10DE&DEV_0A2B&UBSYS_905A104D&REV_A2

I want to update 285.62 for play Battlefield 3

Any brother can help me mod?

Thank you very much.

 

What OS? Do you have BIOS hack?

 

I'm using win7 Pro 64Bit,
And the BIOS is not hack.
THX shurcool

 

shutcool

I have hack the BIOS by paul3000h's post

Then try ComuputerCowBoy's post to update the display driver and install it.
Now it is work. But the brightness can not control. haha.

need time to search how to fix it

 

Try steberg's advice, it seems to fix the brightness issue people are having:

I have tried you way.
And reinstall again.
But no effect.
Thx

 

Back again, trying to update to 285.62 using the modded inf file from laptopvideo2go.com, but like the last time I just get BSOD after a little while with nvlddmkm.sys as the cause. Was able to get 280.26 with coolguy's modded file.

Mostly I just don't understand why that worked, but laptopvideo2go.com do not work (tried asking over there, but never got an answer last time either) Thanks for any answers.

Running windows 7 64-bit. Geofroce 9600M GT

Edit: Saw CoolGuy had updated inf's used those and I'm up and running successfully. Still curious why laptopvideo2go.com's modded files cause BSODs

 

Dear coolguy
I have nvidia 310M GPU, however I tried to replace the inf file with the one you attached but I still get the message "This graphics driver could not find compatible graphics hardware" when I try to run the setup file... is there something I'm doing wrong? I'd be grateful if you could help. Thanks.

 

sorry for digging this up, adding an INF for driver 301.42 for dev 0A2B subsys 9072104D - I cant be the only one who bought a VPCCW2S1E for gaming...or whatever other laptops use that gpu. anyway here it is
