    *update: Feb 9th 2010*
    Instruction guide hiding behind here:
    Modification tools described here can be used to force the NVIDIA graphics driver to detect supported chipset «Intel X58», regardless of what the real hardware chipset present in system. After receiving the identification of a "X58" chipset, videocard driver checks for the correct certificate from BIOS to check "compatibility" with SLI tech, which should be located in the system table DSDT, which is a part of ACPI. Initially, the data tables are loaded from the computer's BIOS, but later, if BIOS wasn't changed, used from the regular OS registry entry by Windows.

    For today, after long time of tool development and research, we got latest version of patch available in beta-status for public testing. These modifications are for education purposes and are provided "AS IS", without any warranties. We (xDevs.com project and developers of SLI patch) cannot be held responsible for any errors, failures or data loss during this procedure, make sure you have backed up all critical data before trying this mod.

    Because of difference of OS kernels and HAL library in every os, every SLIpatch tool hardcoded and dedicated only for specific operating system type and version. Using wrong SLIpatch will cause OS unstable or even damaged. Be aware to use only proper tool version.

    This method and tools has been successfully tested and implemented for following operating systems:

    Microsoft Windows XP 32-bit
    Microsoft Windows XP 64-bit
    Microsoft Windows Vista 32-bit
    Microsoft Windows Vista 64-bit
    Microsoft Windows 7 32-bit
    Microsoft Windows 7 64-bit
    Microsoft Windows 2008 R2

    Install and usage

    Using patch for operation system is very easy now. There is no need to mess with strings, decrypting values, and modifying windows registry to run SLI now. All these work done in background automatically by SLIPatch software tool. All that is needed :

    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.

    If you want to run SLI patched system always - just set default os and delay in System Properties >> Advanced >> Startup and Recovery >> Default operating system and Time to display list of operating systems.

    If you don't need SLI patch anymore you can uninstall patch with next:

    1. Download or use previously downloaded same version proper tool version for your Windows OS in bottom of this guide.

    2. Run command prompt with administrator rights ("Run" menu in Windows Start menu and type cmd there)
    3. Go to directory with patch and run UninstallSLI.cmd.
    4. If everything ok, tool will report "SLI patch uninstalled" and exit.
    5. Reboot.
    6. System should boot in native state now.

    **NOTE: THESE DRIVERS DON'T WORK. THEY WERE AN UNSUCCESSFUL ATTEMPT. THREAD ONLY PRESERVED FOR ARCHIVE PURPROSES**

    Started a new thread. Branched from Solaris17's original thread that I kinda sorta hijacked. We're working together on this now so its cool :D. These drivers are an attempt to get SLI working on XF boards on these newer drivers.
    ---

    Finally they're here! That took way too damn long.. Thanks for your patience everyone! Cross your fingers! In order to develop these, since neither I nor Solaris own a CrossFire board, please provide feedback on the following:

    1) GPU-Z says if SLI is available.
    2) If NV CP shows if SLI is available.
    3) If you can run: rundll32.exe nvcpl.dll,LaunchMultiGpuApplet and what this does.
    4) Also please tell me your motherboard brand and model as well as graphics card pairs and if you 1) have a SLI bridge and 2) if you are attempting to use it or not.

    NOTES:
    1) Don't apply any of Solaris patches. I am working with him on this set.
    2) Uninstall current drivers, restart, then install these like I said before. Otherwise you may have to install twice.

    **NOTE: THESE DRIVERS DON'T WORK. THEY WERE AN UNSUCCESSFUL ATTEMPT**

    *EDIT* Date: 5-22-08 @ 11:56AM
    Version: v2 (Last was v1)


    **NOTE: THESE DRIVERS DON'T WORK. THEY WERE AN UNSUCCESSFUL ATTEMPT**


    Vista (32-bit) v175.16: http://www.megaupload.com/?d=DUS5K8XJ
    Windows XP/2K (32-bit) v175.16: http://www.megaupload.com/?d=YQNVA830 (this is mislabelled - says its Vista but its not)

    EDIT (5-22-08 @ 1:40AM): I think there is something wrong with this set on my card or something (even the unmodded ones don't work) so I'm going to try modding another set I think. Perhaps 175.70.

    EDIT (5-22-08 @ 11:56AM): Download links back up. Problem preventing driver installation should be fixed now. Please test!
    (12:54PM): Removed old text saying drivers didn't work. Whoops.

    EDIT (6-25-08 @ 5:20PM): Added:

    well i'm excited :p i'm on vista x64, but if 32 bit gets working x64 isnt far behind.

    After that, i'd finally get to run SLI :D

    Yeh I'd really like to get an X38 to get some of its virtualization features but it doesn't support SLI :p. So it'd definitely be great if we got this working :).

    *subscribed* I for one would LOVE to see these develop. May not get an HD4k card later if these are confirmed working. 8800GS/9600GSO in SLi on a 975x board anyone? :D

    Are these for Intel based board's only, cause I have a MSI K9A2 Plat (AMD 790FX) that's not in use I would be willing to run tests on, then again that would require a set of NVidia cards (feel free to donate :p).

    Haha. No It should work with any CrossFire board (in theory - if they work .. LOL).

    :)

    Sorry I don't have any spare cards though :p.

    Hey Sinister you should just try running the Setup.exe program to install them. If they don't work when running Setup once try running it again and installing them again after it reboots.

    the original instructions went like this:

    1. uninstall old drivers. reboot.
    2. run setup to install modded drivers - manually install if that fails - reboot
    3. run the command line prompt (may require UAC disabled/admin rights)
    - rundll32.exe nvcpl.dll,LaunchMultiGpuApplet

    Hmm. These don't seem to be working at all actually =/. I'm not sure why. Whatever problem appears to be affecting the Vista version as well as the XP version as well...

    *sigh*.

    I already did a lot of work on these today so I won't be uploading new ones until tomorrow. Sorry guys.

    LOL. Well. The version I did for Vista 169.35 worked fine on my machine. I ported the changes to the 175.16 XP and Vista versions. So I'm not sure what the deal is here.

    But the 169.35 version should in theory work but it doesnt work for 9XXX cards since those were released in 174+ I think. So I'm still looking at it.
