8400gs/nvinject restart works, fails after shutdown
 
with my 8400gs I have been having mixed luck (mostly bad). Sometimes I can get nvinject to work... and usually I can survive a few restarts. So I think I finally have it working...and shut down.

But when I start back up later.. I always(?) lose the success and boot to a blue or black screen?

What's the difference in the restarts working and shutdown/boot failing?

I've been flushing the kext caches and restarting with -f.

EDIT: on one of my bad restarts I found that if I disconnected my DVI>-HDMI cable and reconnected, I suddenly had a screen.... in case that is a clue.

I've tried.. I've not been able to get any EFI strings to work.. I've tried EFI studio and osx86tools. Nothing but black screen from both :(

As I said, this card seems cursed :(

Assuming, This is only your nvidia problems here are some possible ways.

Try booting into safemode and then
1. EFI string with Custom. (Dont select the readymade card)
2. Any of the patched nvidia Kexts (Remove NV* abd GE*), Freshly install the patched kexts. You can get here in downloads section or search for 9f23
3. If yours is 512MB..it might need ROM Modding. search for "Nvinject"+ "512"


If its not a problem with Nvidia..then you can try
1. Use different kernel
2. Use different AppleSmbios kext

How does one know if its an nvidia problem or not? :) (ie. trying a different smbios)

for the download section.. where is that? (I looked under the Wiki/Software and did not see any 9f23 gfx kexts?

My card is 256M, PNY link: http://www.newegg.com/Product/Produc..._-NA-_-NA-_-NA

I've tried doing EFI custom already, but maybe I did not do it correctly... I selected custom, chose 256M, might have had a choice for VGA/DVI vs DVI/VGA, and installed. Did I need to add my card ID to the gfx kexts as well? (does one change the mask values to all FF's, or is that card-dependent?

sorry, I know these are basic questions. I have been trying to read and learn but so much of what "just works" for other folks in their guides is not working for this card.
