Does anyone here have the EFI string/code, or the PC-bios, for "ASUS GF 9800GTX+ DK TOP PCIE 512MB DDR3 2XDVI"? I found one bios at MVKTech, but only the "Dark Knight" version without the "TOP" (overclocked version 775/2360). Does it matter at all which version I use for creating EFI strings?

You don't need the bios for GFX strings as the NVCAP is the same for all 9800 GTX/+. The difference comes with the PCI address of your motherboard. You will probably have to change that from the one that I provided as many motherboards differ.

Noob needs some help. I understand about 1/3 of what is discussed here.
I built a system using the Gigabyte GA-EP45-UD3P and E8500 with a BFG 9400 Video card. I wanted a somewhat low wattage system with decent performance. My system is nice and quiet, and I would like to keep it that way. I feel very fortunate in that I had a very simple (in my eyes) install. Used iAtkos 5i to install Leopard, upgraded to 10.5.6. Used KextHelper b7 to install drivers found using Google search, as well as audio files. Everything works great with about 3-5 hours building and finding and installing appropriate kexts (however, not including the research before I began)
Now I want to possibly screw it up. I realize that I have a relatively low power graphics card and was considering a 9800GTX+ like the Asus above, or possibly these two:
My questions are : Am I correct in understanding that I do not need to install EFI strings if I am running 10.5.6? Also, could someone give some guidance as to the cards. I don't really do much gaming, but I may dabble. I will be mostly encoding video. This is a secondary computer made to run most of the time, hence the lower power draw. The cost isn't a huge factor between the cards, but I would like to balance power with silence. Do I even need to upgrade?

Hi smilesforlife, welcome to aquamac forums.
Firstly of the two cards, I think I would plump for the GTX. It has a very quiet fan with a lot of performance. This is helpful in OSX for general computing as it helps with Quartz Extreme and Core Image. Power in this area gives a increased feel around the desktop too.
If you are using OSX on a PC, you will have to use some form of injector! Whether that is GFX Strings or NVInject or NVDarwin or Natit. With 10.5.6 you will not need to install any drivers for the 9800 GTX as they are already in there, provided by Apple.
What GFX Strings (or any of the injectors I mentioned) do is tell OSX about your graphics card, they are not drivers, which is a popular misconception. On a real mac with a real mac graphics card, this same information is stored in the graphics cards bios. This is twice the size of a PC graphics cards bios, so we have to provide the information in a different way, hence GFX Strings. You can use GFX Strings OR an injector but never more than one at a time. A real mac motherboard bios is built to read this extra info from the graphics card's bios but a regular PC bios cannot, that is why you cannot just stuff a real mac graphics card in your PC and boot!
I hope this explains why we need GFX Strings or an injector such as Natit etc.

Thanks Aquamac!
I ended up with the XFX 9800GTX. I installed it per you instructions at the beginning of this thread using KextHelper b7. However, now I only have 1024x768 resolution, down from 1920x1200. Here is my system profiler.

Thats because Quartz Extreme and Core Image are not working. From the information above there are no display kexts loaded so you have just basic VESA resolution.
Delete NVInject and install GFX strings. If you want to try the easy way to start with, download and use OSX86 Tools to create the string. OSX86 Tools

Well, now I've gone and done it. I followed the directions for installing GFI Strings but noticed when I replaced the com.apple.boot.plist with the new .plist it was saved as a text file instead of a .plist file. I figured it might reconfigure in startup. Wrong. Now when I boot up it says it cannot find the com.apple.boot.plist file. The old one is in the trash but not emptied. Is there any way I can recover that from the terminal via the iAtkos installer?

Oh Dear,
Well here is my single apple.com.boot.plist, so you can use this. Hope you have another computer you can connect your hard disk to, then you can navigate to the folder and drop this into the correct file. You decided not to use OSX86 Tools? Do you know what your pci address was, if so I can make the correct plist for you. It may be that the one I am supplying here will work fine, but at least it will let your computer boot with it installed.

Good grief, I didn't even think to take the hard drive out! Thanks for pointing it out. So the proper .plist is in the proper place. I put the string in with OSx86 Tools, and the resolution is fine but still don't have QE enabled. Here is the info.

Are you running a DSDT.aml file. If so please delete it. Do you still have all the apple drivers installed from 10.5.6? You will need all of these. Don't delete any. You could also try installing NVDarwin. Leave your com.apple.boot.plist in place.
Re: NVIDIA 9800 GTX Working in OSX86 « Reply #59 on Apr 20, 2009, 7:17am »
Not sure what a DSDT.aml file is or where it is found. I just tried to install kexts from reply #29 and repair permissions, now when I boot I get a black screen after the gray apple screen, and every other time it will go into the normal boot cycle. However, Rotation is now supported.
