First Thanks for you reply.

Yes, i tried EFI Studio and i choosed GeForce 8600 GT 512MB from the list and after that i restarted the laptop and booted with -v(and-f) and also started again normally and in all cases what i got is just black screen. the computer is running but with black screen (no mouse pointer shown).

so unfortunatly EFI studio did not work with me.

Also i tried to use ox86 Tools Utility by trying to add EFI and i choosed my card but when i tried to save i...t it gave me this message:
/bin sh not exist

any thoughts.
You may end up having to get your NVCAP info, you dump the
Video ROM under windows or dos and run it threw NVCAP Maker
on the mac, I use GPU-Z under Windows to dump Video ROMs

The NVCAP info, its info on the video output ports on you video card,
you will get a set of numbers like this

"04000000 00000300 0C000000 00000007 00000000"
or
"04000000000003000c0000000000000700000000"

Now go into EFI studio and select your video card, click "Add Device"
now click "Save XML" now open that file with ether "PlistEdit Pro"
or "Property List Editor" and add your NVCAP info and save the file
now open EFI studio and click on File then Open XML File, and install
like you would normally with EFI studio,

Or if you are worried about it not working, just edit your
com.apple.Boot.plist file in the /Extra folder, and use Empire EFI
Boot CD or the The myHack Installer installed to a thumb drive
to boot with if you unable to boot after the changes

This way is almost the same as before

Go into EFI studio and select your video card, click "Add Device"
now click "Save XML" now open that file with ether "PlistEdit Pro"
or "Property List Editor" and add your NVCAP info and save the file.

Now copy com.apple.Boot.plist from the /Extra folder to the desktop
open it with TextEdit and add

Code:
<key>device-properties</key>
<string>PASTE YOUR HEX HERE</string>
Like this

Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Kernel</key>
    <string>mach_kernel</string>
    <key>Timeout</key>
    <string>5</string>
    <key>Kernel Flags</key>
    <string>arch=i386</string>
    <key>EthernetBuiltIn</key>
    <string>y</string>
    <key>Graphics Mode</key>
    <string>1024x768x32</string>
    <key>device-properties</key>
    <string>PASTE YOUR HEX HERE</string>
</dict>
</plist>
now open EFI studio and click on "File" then "Open XML" File, now click
on "Hex String to Clipboard" and paste were "PASTE YOUR HEX HERE"
was.

</plist>
And now copy it back to /Extra folder

I found some NVCAP numbers for you to try
