Sorry for my english.I have a asus M50Vn notebook with Nvidia 9650M GT .When I update my graphics card drivers to 186.81,I can see some pixel errors and some little stripes on the screen and my computer get freezing after a while.However,one of my friend has a asus N50Vn notebook whose graphics card is also Nvidia 9650M GT and his notebook works fine with Forceware 186.81.I decide to use MMTOOL(a software used to edit AMIBIOS) to extract VGABIOS of Nvidia 9650M GT from BIOS of M50Vn and BIOS of N50Vn,so that I can use NiBitor(a software used to edit Nvidia VGABIOS) to see the difference between VGABIOS of M50Vn's Nvidia 9650M GT and N50Vn's. I find that voltage setting in VGABIOS of N50Vn's 9650MGT is 0.01v higher than M50Vn's VGABIOS setting.So I use MMTOOL to replace VGABIOS of M50Vn with VGABIOS of N50Vn's 9650MGT,then reboot and press F4 to flash this modified bios.Now my notebook works fine with Forceware 191.07 and graphics card can work in a lower clock when it is idle.I hope this can help those who have the same problem with me.
Modified BIOS of M50Vn and N80Vn is in the Attachments.Some guys in another notebook forum have tried and scuceeded to solve the problem of N80Vn in the same way.

You don't need to load it...I load it because I need to modify it.The file which I upload has been modified.All that you need to do is to flash your bios with the file(the file is a bios rom file).

[KaZo]

first copy this file on c:\ . restart and go into bios setup. open this file in bios easy flash. start flash and wait! =)

(for german users: ladet euch die datei runter. die datei muss unter c:\ liegen. danach geht ihr ins bios setup rein. dort findet ihr easy flash. öffnet die datei, start flashin, warten.. fertig) ^^

Hi at first i wanna thank you for the bios...its working for the fact that there are no more freezes...but now is the problem that the colours are unreal, to intensiv the red fpr exemple is a kind of orange...its very hard fpr the eyes...hope someone can help me to solve the problem...all coloursettings are right

I think you should uninstall your graphics card driver completely and reinstall it.If that doesn't work,you can try to reinstall your Operating System. The color issue is usually related to unclean install of driver.

you may try to reboot your notebook and when you see ASUS logo,press "F4" button to flash your bios.you can use winflash to do this,too.
I've tried 212 and it does work.

I find that M50Vn's Bios 212 have fixed this problem,so I update N80Vn's VGABIOS version to that of M50Vn's bios 212(version 62.94.75.00.0C).Anyone who want the new modified BIOS of N80Vn can use this link to download it:

Thank you for your efforts.

Test result comments:
- Not as stable as N50's Video Bios 62.94.75.00.07 on the "cold start-up" test.
- Stable on the "Warm start-up" test (reboot).
- Stable running of "Heaven Benchmark" and other various software products (see below).

Assumptions:
- Flash N80VcASlic.208 (Video Bios 62.94.75.00.0C) into ASUS N80VN notebook.
- Windows 7 RTM (all driver and security updates applied).
- nVidia Forceware version 186.81

Cold start-up test, steps are:
1. Shutdown N80VN notebook.
2. Unplug AC + Battery.
3. Wait for 15 minutes.
4. Plug battery + AC power.
5. Turn on notebook.
6. Windows 7 may produce BSOD (2 out of the 5 test runs) before the login screen. Next reboot/restart of Windows 7 (warm start-up) is ok (boot into Windows 7 desktop and running various software products).

I'm went back to using the N50's Video Bios 62.94.75.00.07.

Software used for testing:
- Crysis
- Heaven Benchmark, from http://www.unigine.com/download/
- Street Fighter IV
- Windows Media Center

Disclaimer: Different test results may occur in various variants of nVidia GeForce 9650M GT (different Video Bios version + chip stepping/revision + board design).
