in this folder there will be SLI mods for XP, Vista, Win 7 32bit & 64bits, i could not find the site i found it off of.

*install the newist Nvidia drivers (older drivers seem to be buggy as hell)

1. Download proper tool version for your Windows OS in bottom of this guide.
2. Unpack it to some directory on harddrive. For Windows Vista or Windows 7 disable UAC.
3. Run command prompt with administrator rights ("Run" menu in Windows Start menu and type cmd there)
4. Go to directory with patch and run InstallSLI.cmd.
5. If everything ok, tool will report "SLI patch installed" and exit.
6. Reboot.
7. During boot there will be "extra OS" selection, marked "SLI enabled". This is one to use with SLI patch active.
8. Select SLI enabled system and boot it.
9. System should run SLI now, until BIOS or motherboard changed.

(Note: do not uninstall this SLI mod, only way to re enable the SLI mod is to reinstall windows if you uninstall SLI) i made this mistake and i could not reinstall the SLI mod.
