This one is one of them.

Are you using latest Chimera Bootloader?
Are you using GraphicsEnabler=Yes ?

Starting Chimera 1.40 8400GS is listed

I have exactly the same card I have been struggling with every waking hour for days. I can't change resolutions.

I have used the latest Chimera and set GraphicsEnabler=Yes

After a lot of playing around I managed to upgrade to 10.7 by using...

"-x -v PCIRootUID=1 npci=0x2000"

I think installed the Kext (http://www.kexts.com/view/1534-download.html). All seem to be fine, but now when it reboots it halts on the Apple Logo screen. If run "-x -v PCIRootUID=1 npci=0x2000" i can see that it loads the kext, but when loads the grey apple screen.

Any ideas as to the problem?

Cheers

Always run System Utilities in Multibeast after making kext changes.

I am using Snow Leopard 10.6.8.

From another thread:

This is how I got my 1GB Zotac 8400GS VGA/DVI/HDMI working under Snow Leopard 10.6.7:

1. Added Device-ID to NVDANV50Hal.kext in SLE
2. Added GraphicsEnabler=y to Boot.plist in Extra
3. Boot via VGA or HDMI (DVI is usable if you boot VGA then swap)

Some notes:

1. The booting order is important (boot via either VGA or HDMI, but not DVI - you'll get a black screen at the desktop)

2. DVI is junk on my Zotac. You can use it if you boot up to VGA and then swap to DVI, but it "forgets" that setup every time you reboot. Fortunately, an HDMI to DVI cable works just fine.

I don't know how much of this will apply to your particular card, but this is what worked for me after much tinkering. It works and it's cheap!

Hi,

Thanks for this information but will the VGA option get me past the part where I'm stuck at the apple screen?

It is crashing on startup because there is something wrong with a kext file. If you put your original files back, remove NVEnabler.kext, and run System Utilities in Multibeast, that fix that. Then try full functionality solutions again.

Hi,

Thanks for all the help, i didn't have to do anything apart from go out and buy a VGA cable. It boots fine now without any problems and works flawlessly. Very strange.

Cheers for all the help.
