Hi there,

 

I recently installed Mac OS X from my Retail Leopard DVD. I've got most(I think) things working.. previously I had Kalyway installed.. with NVKush for my Graphics, which gave me QE & CI Support.. I've tried using EFI Strings for my GeForce 8400m GS 128mb, which give me a clean display, but I have lost the Quartz Extreme, and Core Image (is now only Software, not Hardware Accelerated).

 

I've tried using MacGirls boot.plist, which has given me the same thing as what I already had.

 

Does anyone have any tips I can try? or a solution for me?

 

Many thanks,

Chrisdarl

I think Chrisdarl is trying to get graphics back in 10.5.5 which at this point nvinject and other forms of inject will not work =[

 

efi strings would in theory fix the problem but I'm not quite sure how to make it work I've always used nvinject. I have an idea that mite make it work and its not risky to try either but try using this code in your com.apple.boot.plist it should recognize the graphics on startup using EFI strings. I would try this myself but for some reason my efi boot loader is not working rite I'm having to boot from the dvd.

Yes, you have to use the 10.5.2 kexts. I have been unable to get QE/CI to work with anything higher than 10.5.2 while using an EFI string. v1.0 of the graphics update is the only one available.

 

Shiftedx, that EFI string will allow the graphics card to be detected but will not enable QE/CI.

I tried copying :

Geforce.kext

GeForce8xxxGLDriver.bundle

GeForceFXGLDriver.bundle

 

From LeopardGraphicsUpdate v1.0 (10.5.2 kexts), into my Extensions folder....

When I boot back into Leopard, I get a messed up display, multicoloured pixels in blocks.

 

btw. I'm using macgirl's com.apple.Boot.plist

i solved the problem on mine downloading the whole leopard graphic update and reapplying it, then using only Macgirl's efi string. i'm not sure but it seem to me that the latest nvidia driver package (10.5.5 beta?) change another kext too, not only nvidia related,try to open the pkg with pacifist (i erased it sorry). i can confirm on mine too the latest package recognize the card but don't enable qe/ci (8400m gs)

For what it's worth, Apple is offering the download here:

 

http://www.apple.com/support/downloads/leo...csupdate10.html

 

I have a 7800GTX running iAtkos v4 and I have had zero luck getting it to work. I have working graphics and dual monitors but I do not have QE/CI.

 

I have tried NVInject and an EFI string w/o NVInject and get the same result either way

 

I am going to attempt this update this evening and see if I can restore graphics. Without CI, I can't play any games!

 

Aside from that, my system is 100%.

 

Current setup:

 

Gigabyte GA965

2 250gb drives

1 500gb USB 2.0 drive

Realtek 883 audio

BFG GeForce 7800GTX card

iAtkos v4 (10.5.4)

 

Wacom tablet, CF card reader, a few hubs, and more...

Okay! IT WORKED.

 

Here was my procedure:

 

  1. After the iAktos install, Go get Leopard Graphics Updater 1.0 from Apple.
  2. Run in through Pacifist and unpack it someplace, say, on the desktop in a folder called 'lg'
  3. Open up Terminal. Do the following:

  cd ~/Desktop/lg
 for i in *;  do rm -rf /System/Library/Extensions/$i;  cp -pR $i /System/Library/Extensions; done
 rm /System/Library/Extensions.kext*

 

Now, reboot. This should fix the Nvidia issue by replacing all of the newer kexts with the old 10.5.2 ones.

Unnecessary. Just go download the Leopard Graphics Update from Apple. Open it up using Pacifist. Right click on the package in Pacifist and choose "Install to default location". Use OSx86 Tools to delete the extensions cache and repair permissions. It should work.

 

Doesn't the above command remove ALL of the kext's in the Extensions Folder? Not only the Graphic's ones.. Wouldn't that sort of defeat the point of me upgrading to 10.5.5? I may as well stay with 10.5.2?

 

Just do what I said above and you'll have it working.

So, I've got my 8400m GS card working in 10.5.4 via NVkush.kext but now I'm trying to find out what is the EFI string in order to update to 10.5.5 and get QE/CI working...

 

I've already tried the following strings: (with no success)

i know this is an old thread, but i too am looking for an efi string for an 8400m gs 128mb.

 

My card is in a dell vostro 1500,and i've had no success with strings so far...

 

i used to have an 8600m gt, and i had the same problem....

 

 

works fine with nvdarwin, nvkush, nvinject, natit, etc etc etc,,,,but not with efi strings......

 

 

 

has anyone ever had an M graphics card working with strings?
