vvimp MEGAUPLOAD - The leading online storage and file delivery service

2.drag cmd prompt on to the desktop . start run as adminitrator >type Bcdedit.exe /set nointegritychecks ON
3.u can check in dxdiag>display for conformation

OK. I finally have this working on my dell 700m after using a mix of this solution and another that I tried with the beta build and got BSOD. Turn off integrity checks as described in step 2 above then download the drivers. Reboot in safe mode and install the drivers as decribed above. Click the "Scan for hardware changes" button at the top of the device manager and let it whirr away until it gives you a dialogue box saying the 855 drivers are ready to use. Reboot.

When you reboot the screen will display as before in VGA mode, but when you log in the new drivers will be detected and installed. The screen will go black. Reboot when the hard disk has become idle. You should now be running with the intel drivers. If you right click on the desktop and click screen relolution, then click advanced settings and then list all modes, you should be able to change to 1280x800 32bit true colour mode.

Hope this helps somebody.

This worked like a charm for me with build 7100 on my Dell 700m!! Thanks gopinndn and BigJimmy

Thanks everyone for lots of useful information. I have eventually got my Sony Vaio VGN-T2XP working with windows 7. I had trouble using the basic procedure outlined by Frustrated (post 42) above. However, adding two ingredients into the mix worked for me:

1) Follow Arathranar's (post 74) to disable the start up screen which forces a certain resolution and default graphics drivers ("running msconfig and checking Boot->OS boot information. Instead of the animation you now get text showing driver loads and the 0x7E STOP blue screen")

2) For some reason the "bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS" command seems a bit unreliable. Another way of disabling these checks is "Use gpedit.msc and navigate to: User Configuration -> Administrative Templates -> System -> Driver Installation and enable the "Code signing for drivers" and then choose "Ignore"." For more details see here.

Very pleased, this will give another lease of life to my laptop.

My Samsung Q30 has become a second life with windows 7 RTM and full resolution 1280x768. Thanks to everyone for the helpfull tipps. I followed the same procedure as flyingfurryfigs and sushah23 in the last 2 posts with final sucsess after month of trying different things.

Using instructions in this link

Install 855GM Series Video Driver on Windows 7 - Tutorial

I've gotten my Dell 700m running Windows 7 Ultimate RTM going at 1280 x 800, 32-bit. I couldn't use the DriverMax solution, the notebook was running factory XP

A note that when you install the new driver in step #5, the screen blanked out for me. Had to wait a bit for the hard drive to stop spinning and performed a hard reboot. Didn't bother restoring security on the vgapnp.sys file after step #5

Flaming Homer,

I am the author of that tutorial. I tried to post it here for all to use but it said that administrator has to evalutate it. I guess someone deleted it!!!!

Anyway,

It is nice that the tutorial worked for you

. It took me a while to figure this mess out.

I would advise you to do STEP 6 to bring the vgapnp.sys to usuable state.

Thank you very much, I will continue with the rest of the steps - I actually copied vgapnp.sys to vgapnp.sys_ after disabling file security, so I'll just copy it back. None of the other solutions listed here worked for me.

Lexxion,

you da man!

I just followed your instructions precisely to get my Sony T1XP up and running in glorious widescreen. Thanks so much for taking the time to pass on your expertise.

Lexxion,

Thank you for your walkthrough on getting the Intel 855 driver going on Windows 7.

Your procedure worked perfectly on my Sony VAIO PCG-TR3AP (with Intel 855GM Video)

I am now writing this using a beautiful 1280x768 resolution under Windows 7.

This machine has never been faster, Window 7 definitely seems to be more efficient than Windows XP.

thanks,

Larry

Lexxion,

I followed the walkthrough on getting the Intel 855 driver going on Windows 7 but i don´t understand this:

cacls c:\windows\system32\drivers\vgapnp.sys /G peter:F

my pc name is Vaio and i put this:

cacls c:\windows\system32\drivers\vgapnp.sys /G Vaio:F

and it says: Invalid Parameter "Vaio:F"

what i do wrong?

i have a Sony VAIO VGN-T2XP/S (with Intel 855GME Video)

i want to put 1280x768 resolution under Windows 7.

thanks,
