I've Tried Everything

[mark1984]

Hi,

 

I'm hoping someone can help me, i've installed iDeneb Mac OS X 10.5.6 and managed to get everything working apart from the graphics card.

 

My Spec;

 

Processor - Intel Core 2 Duo E8400 Socket 775 3.0Ghz

Motherboard - Asus P5KPL-AM iG31

Graphics Card - PowerColor HD 3850 512mb GDDR3 256bit PCI-E (id 9509)

Memory - 4GB Crucial RAM

 

I cant boot into normal mode as i get a scrambled picture, it shoulds like its working but i just can view the screen as its white and black squares all over it. I've tried all the methods i can find - Natit.kext method here and radeon hd pkg installer here. When i try these methods it prevents my system from loading, even into safe boot, so i end up doing a fresh install...

 

I havent tried EFISTUDIO_EXTNEDED method here as i cant find the files required.

 

I can currently boot into save mode using flag -x "Graphics Mode"="2560x1600x32" but this gives me limited usage.

 

Has anyone got any other methods that I can try?

 

Display Details:

 

Type: Display

Bus: PCIe

PCIe Lane Width: x16

VRAM (Total): 256 MB

Vendor: ATI (0x1002)

Device ID: 0x9505

Revision ID: 0x0000

Kernel Extension Info: No Kext Loaded

 

Any info or help would be fantastic.

 

Many thanks in advance.
