Xeon e5450 3ghz mod 771 to 775 LGA and Nvidia GeForce 9400 GT High Sierra Problem!.. I need help for edit my DSDT

[x_sirius]

Hi, I would like to know if you can help, I have a problem with my old system, I have tried to install High Sierra, but I have not managed to make the acceleration of graphics work on my video card NVidia Geforce 9400 GT, eh intendo a lot of methods without Any success, the system recognizes my card and all its data correctly but the acceleration of graphics does not work, this problem is due to install a processor Xeon e5450 3.0ghz Mod 771 to 775 LGA, since installing this peocesador the graphics stopped working and what appeared was a glitch on the screen that shows absolutely nothing, to enter the system I had to enter with bootflags nv_disable = 1 in clover configurator, I have managed to see in other post information to this problem and say that it has been solved with the bootflag npci = 0x2000 and npci = 0x3000 to solve the Glitch on the video card, in my case the boot system is restarted, after a lot of frustration for wanting to start with the graphics, delete all the kexts of graphics cards ATI, Nvidia, from the folder System \ library \ Extensions \ and success !! .... the glitch of the graphic card disappeared completely, the problem of the glitch on the screen was generated by the kexts nvidia, now I can start with Inject Nvidia, but e peoblema is that now the graphics do not work with acceleration, I do not know what to do with this peoblema, my motherboard is Intel DG41TY. another person suggested modifying my dsdt.alm but I could not compile the code provided to me, I get an error in DSDTSE. please maybe you can help me with this problem. I will leave you the link where is the information to compile the code of my nvidia geforce 9400 to my dsdt.alm...... I am the user X_SIRIUS https://www.tonymacx86.com/threads/nvidia-geforce-9400gt-on-sierra-not-works-ok-kernel-panic-nvdastartup-kext.206208/page-2#post-1793409 

 

 

I'm trying to install the code in the dsdt.alm I copy the respective code to my Geforce 9400 GT 1024MB nvidia card.

But when I want to compile the file, the DSDTSE program tells me that I have 1 error, 3 warnings, 1 remarks, 49 optimizations.

I try to find the file dsdt.alm that the program saved and I can not find it.

My Motherboard is Intel DG41TY.

here I will upload my dsdt of my current mother card, maybe you can help me compile the code without errors, please

 

This is my DSDT from my Motherboard Intel DG41TY acpi_dsdt.aml

this is the procedure to follow, but I can not compile the code to my DSDT, please be eternally grateful if someone can help me with this, because I get errors in the DSDTSE editor, I attach an image of the errors that the Program. 

 

And this is the Glitch, kexts Nvidia error whit Xeon E5450..
