How To: Enable SLI on pre-i7/i5 hardware

[oiluj]

I'm going to try new method under Windows 7 x64 (already succeeded enabling SLI with HALmod and 191.07 drivers) but... I don't wanna mess up with boot.ini and boot options, as I already have a custom boot menu with XP x32, Vista x64, W7 x64 and Ubuntu 9.10, so...

What about if I replace original "ntoskrnl.exe" and "hal.dll" files with "ntoskrnp.exe" and "halsli.dll" (renaming them to "ntoskrnl.exe" and "hal.dll", of course) ??? Will that be enough??
What does "osloadw7.exe" do? I don't see any similar original file in "%SYSTEMROOT%\system32\" folder, so in this case... I don't know what to do with this file.

Thank you!!

The "similar original file" you're missing above is 'winload.exe'.

And what you just described is, pretty much, what InstallSLI.cmd does anyway, but without you using the automated installer to coerce bcdedit into making a new entry, if your renaming scheme doesn't work, you broke your Win7 install.

if your renaming scheme doesn't work, you broke your Win7 install.

Yeah, but prior to replacing, I can "backup" original 'ntoskrnl.exe', 'hal.dll' and 'winload.exe', simply by renaming them to 'ntoskrnl.exe.bak', 'hal.dll.bak' and 'winload.exe.bak', for example.

OK, so, what i should do if I don't wanna mess up with 'boot.ini', boot options and so on would be:

1.- Rename original 'ntoskrnl.exe', 'hal.dll' and 'winload.exe' files to 'ntoskrnl.exe.bak', 'hal.dll.bak' and 'winload.exe.bak', for example. Or copy the 3 original files to any "spare folder".
2.- Copy modded 'ntoskrnp.exe', 'halsli.dll' and 'osloadw7.exe' to my Win7x64 '%SYSTEMROOT%\system32\' folder, and rename them to 'ntoskrnl.exe', 'hal.dll' and 'winload.exe', replacing the original ones.
3.- If system doesn't boot, undo the changes, so system uses original files again and "nothing happened here".
4.- If system boots, just enjoy.

Is that correct?

ok. about x32 system. you should do next:

did you ran installsli.cmd as administrator?

run as usual windows:

run cmd.exe as administrator
type bcdedit.exe and hit enter

make a screenshot that the command showed

post to me

Yes I ran as administrator

But surely the fact that this has happened on both Windows XP and Windows 7 means something isn't right?

[MikeTyson]

one of them will work

Yea because it never uninstalls properly

Ok I'll try them both now
