I have spent a long time trying to figure out how to get my Intel video chipset working properly on my X40. I tried many different methods, and this is what worked, with one modification: before running any of these steps, go to Computer / System properties / System protection / Configure and select “Turn off system protection”. After you have completed the steps below, re-enable system protection.

Install 8XXGM Series Video Driver on Windows 7 – Tutorial
Tested with 855GM Chipset
By Lexxion
Problem
When installing 855GM Series video driver Windows 7 reverts back to Standard VGA adapter after restart. The problem is that 855GM Series video driver is not native for Windows 7 and it will always choose Standard VGA Adapter as native video driver. A lot of older laptops have this video chipset. I read a lot of tutorials on the net and nothing worked for me. So I figured out a UNIVERSAL way to get it to work, I think :)
Solution
The only driver that worked for me is: Intel(R) Graphics Controller 6.14.10.3722 . The reason why is that Standard VGA Adapter (Win7 native) is the same version (6.14.10.3722) but it has newer release date. Newest Intel driver 14.19.50 did NOT work. So get yourself the working video driver below. After Windows 7 install you will see that Standard VGA Adapter is installed and there is an exclamation mark on the “video controller”. In order to install the driver we need to get exclamation mark on “video controller (vga compatible)”. This spot is occupied by Standard VGA Adapter. Even when you unistall Standard VGA Adapter and install new driver after the reboot Standard VGA Adapter comes back. We need to disrupt Standard VGA Adapter from being installed. My way of disabling the adapter is to edit the driver file for it “c:\windows\system32\drivers\vgapnp.sys”. There might be another way for letting Windows stop installing Standard VGA Adapter but I did not find it.
Intel(R) Graphics Controller 6.14.10.3722 (Windows)

Instructions
STEP 1
Make sure you unistall video drivers that do not work. If you see exclamation marks on your previous drivers in Device Manager, unistall them. Your Device Manager should say that you have Standard VGA Driver installed under Display category and exclamation mark on “video controller”. Make sure you restart PC when asked.
STEP 2
We will need to edit “c:\windows\system32\drivers\vgapnp.sys” file now, but there is a problem. Windows Vista and Windows 7 will NOT allow you to edit system files even when you are the admin. Changing security attributes of that file did not work either. The file is owned by “TrustedInstaller” service. We will need to own the file and give ourselves the full control to edit it.
Click ‘Start’ and in ‘Search’ type ‘cmd’. The result will show on top. Right-click on ‘cmd’ and choose “Run as Administrator”. If your account does not have admin rights you might be prompted to enter username and password. I used account that already has administrator priviledges. You should have a command prompt with administrator priviledges.
STEP 3
Lets say my logged in username is peter
First command you do is:
takeown /f c:\windows\system32\drivers\vgapnp.sys
This will give ownship to the current user. You should see a message saying SUCCESS etc..
Second command you do is:
cacls c:\windows\system32\drivers\vgapnp.sys /G peter:F
There will be a confirmation message so type ‘y’. This will change the security attributes to give you ONLY all the permissions for the file. If you are paranoid as me and want original permissions restored, I will show you how to restore the permissions to the previous step later on in this tutorial :). If ‘cacls’ command does not work you can try using ‘icacls’.
STEP 4
Open c:\windows\system32\drivers\vgapnp.sys in any text editor. Just add any character to the begining of the text. Let’s say we will add character x . So the text should start with xMZ and the rest of stuff. Save the file. This edit will render that file unusable.
STEP 5
In Device Manager uninstall Standard VGA Adapter. It will prompt you to restart so do it. After install you will see a message saying that certain devices did NOT installed successfuly, which is GOOD :). Go to Device Manager and you should see the exclamation point next to “video controller” and “video controller (vga compatible)”. Right-click on “video controller (vga compatible)” and do update driver. Choose “Browse for the Driver” (or something like it :) ). Point to the driver directory that you downloaded and extracted (win2000). Click “OK”. Wait for the driver to be installed. It might hang for a little (It will say that window is “not responding”). Do not worry as this is still installing the driver. It will prompt you to restart so do it. (If it does not prompt click anywhere and wait for message). After restart it will finish installing the driver.
Congratulations!!! You should have a working video driver!!! :)
STEP 6
Open c:\windows\system32\drivers\vgapnp.sys in any text editor. Remove the first character you put there which was x. Save the file. Your file will be usuable again :). You can stop here if you want, but if you want to restore the permissions for the file to original state go to next step.
STEP 7
Right-click on any other file in the c:\windows\system32\drivers. Choose “Properties”. Go to “Security” tab. Now compare that security tab with the security tab of c:\windows\system32\drivers\vgapnp.sys. Just make sure the security tabs of those two files look the same (all tabs and advanced options). In order to add “TrustedInstaller” it is not the same as regular usernames because it is a service.
You will need to type “NT SERVICE\TrustedInstaller” (without quotes) when adding it to own the file and to have all permissions. Once you done editing you can delete your account from c:\windows\system32\drivers\vgapnp.sys, because it was not there from the beginning. We took control over and the previous commands added it by default.

Unfortunately, bit drivers are not available at this time.
Cheers for that, in the end , without that I would never have gotten the video driver to install..
only leaves me with the 82801dbm controller to go….
Well done !!
It worked for me on a Thinkpad X40.. Many thanks!
PS. For me, the video driver was the only driver that the Windows7 didnt recognized after Windows Update. All other drivers are working properly.
thanks for all
Thank you so MUCH!!!! You are my HEROE!!!!!!
nov 2012/ playing around with the old x40. now scoring better than 1.0 in windows experience thanks to your guide. Worked great and well explained.
We should fire up Windows 8 on these old soldiers and see how they perform!
Instead of the part off Cmd and cacls or icacls i think that we can browse to the file, right click,and at the tab of security just give your user full control.. am i right?
That didn’t work at all FYI for Windows 7
Um, yes, it did work, at least the last couple times I tried it. What part didn’t work for you?
I absolutely cannot modify the SYS file following your instructions to the T. I can even see that I have granted access to the file via the cacls command but still getting access denied. Oh well.
Thanks a lot your method gave me insight as to what is blocking my older driver from working, so having that in mind instead of uninstalling the standard vga driver from win 7 i simple right clicked on it and disabled it then i seached for the new driver where i had downloaded my new unzipped driver and wholaa my mate’s computer is working perfectly, dankie san
Thanx bro!I encounted an obsticle at ‘STEP 4’ coz i used Office WORD do edit but i couldn’t save afterward, i then used ‘WORD PAD’ which came standard with window7 to edit, typed ‘x’, clicked save icon on top left & didn’t even get ‘file unusable’, then uninstalled ‘VGA’ then updated & installed successfully without any ‘windows not-responding’, clicked ‘restart now’ problem solve.Thanx a million PAUL!
Glad it worked!
Hi Paul, it’s April 14, 2014 – After spending hours trying to figure out how to solve the problem with the resolution on a Dell Latitude D505, I came across your site and after following your instructions, ‘- Voila’- Everything is working perfectly.
