Something puzzling with nVid GeForce 210.....?

[Jimmiegin]

Hey you all! 

I have at the moment, three desktops in front of me. 2 of which have GeForce 210 nVidia graphics cards in. To my right is an Asus A88XM mobo with A10 AMD APU and a EVGA 210 graphics card. The AMD is running Mavericks and upon completion of install the graphics card was fully supported with absolutely no bother at all! Great!

 

To my left is a Dell Optiplex 760 that is running mavericks.... or was, i am now reinstalling after a F**** up. When i install on this optiplex i have to remove all NV kexts and enter strings to get video out. Then reinstall all NV kexts WITHOUT NVEnabler.kext, remove graphics controller kexts and generally faff to get resolutions and QE/CI. 

 

When i then install yosemite over mavericks, one time i got full working graphics, the rest of time.....too many to count now.... no support on my 210 card at all. I am using kext-dev-mode=1 as i have seen that for some reason yosemite has at times not liked loading those NV kexts and comes up with something about 'unsigned kexts'. I could be wrong I am using kext-dev-mode=1 so that Yosemite loads the kexts, is this correct? So now I am on a mission to Yosemite fully working by way of dirty install on my Mavericks SSD as I had success one time and got full support no problems but messed it up trying to use one of the "beasts" to install a boot loader (I might add that I shall not be using such methods again since I have read, and seen, evidence of untoward shenanigans!). In short, how can I install Yosemite on my Dell 760 and maintain full graphics? Anyone with any ideas of what i need to do to get things back to fully working please lend some knowledge.

Thanks for reading

I have an Intel CPU, I use the Boot Flag: GraphicsEnabler=Yes to get my card to work. Thats all you should need to do.
