nVidia 8400 GS 256 Mb

I guess I have this problem for a while now and tried many different approaches to fix it. So the problem is:

I have 8400GS and monitor connected via VGA port (not DVI, as I have no DVI monitor at this time). Problem is that once a while OSX (IPC-10.5.6) show me blue screen instead of login screen at startup and fullscreen game are turning videocard off too. I think problem is that it tries to take DVI port instead of VGA or something. Also same problem if I try to change resolution - I have to change it few time blindly for it to show me desktop instead of plain blue screen. I'm using nvinject at the moment, but I had same problem with EFI strings too. Had anyone meet same problem with it? Is there any solution, for example to tell via EFI string to use only VGA port and nothing else?

P.S.
QE/CI works fine with both NVInject and EFI strings though... if I playing, say. WOW in windowed mode it work quite fast and I have no problems at all. But if I go into fullscreen by mistake monitor turns of like VBLANK.

I have a XFX 8400GS 256Mb id 0x06e4 working fine on games and everything else with the VGA port, as I don't have a DVI monitor. Right now I'm using EFi string but I've tried every injector out there and they all work fine at stock config, no edit needed.
What you may try is to create a custom EFI string and see what comes out.
To do that I've used OSX86Tools but I think EFIStudio should work too. Just make sure to select VGA/DVI-I as your output.
Hope it helps.

Ok, I gues I'll give it a go, as I don't really have a choice, although I think I've already tried that, but I'll recheck it for sure. It just I bought 8400GS when I fried my 8800 GTS 512Mb, which worked just fine with EFI strings (by OSX86Tools), so now I'll have this card for a while, till I'll buy new

use NVkush or efi string

MX1333 · #6 04-14-2009, 01:09 PM

thanx. have tried that. not wrkg. dunno what seems to be the problem.

NVKush had earlier wrkd - on my 10th reinstall of iATKOS 10.5.5 but i wasn't aware of EFI strings - applied those via EFI studio+the 9f23 installer - voila. no QE/CI

i'm bak with NVKush but still can't get QE/CI. don't wish to go+reinstall everything again.

hi

i removed the EFI strings from com.apple.boot.plist & now i've QE/CI with NVinject

woo hooo. took me three miserable weeks including a fatal crash which i somehow recovered(always backup your extensions via OSx86 tools!!!) to figure this one out...

i have attached a few NVinject kexts with this - i don't remember which one worked for me - i don't even know why i installed EFI strings in the 1st place...all the very best for you QE/CI...yes, you can do it...

here's how to remove the EFI strings:

Code:

sudo -s
    [enter password when prompted]
    nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

This will take you to a text editor showing you the contents of your com.apple.Boot.plist. Look for these two lines:

Code:

<key>device-properties</key>
    <string>YOUR LONG EFI STRING HERE</string>

Using your arrow keys, navigate the block cursor down to each of those two lines and hit CONTROL+K on both. This will cut the corresponding line out of the script (quicker than hitting the delete button, trust me).

When you're done, hit CONTROL+X and then Y, and ENTER to save the file. Now simply restart OSX, and you should boot up again without EFI strings.

Hi,

Thank you for posting these.

I've installed these kext's but I've having a problem running Front Row.
All I get is a black screen. I can hear the sounds of the interface when pressing up/down etc..
but nothing on screen. Also I've noticed that even though the kexts seem to be detecting the card,
the graphics are still slow to render on Dashboard transition and Expose.

Is anyone else having a problem like this or can offer any advice??

Thanks In Advance

Working Now.

Thanks Again MX1333!!

I tried the kext in Folder I (overlooked it), and removed the EFI strings as described.
(Apologies, I know it was in prev post, but only gettin to grips with this

)

So all seem working fine.

Until 10.6
