UPDATE 5: Now GPU and sleep work perfectly! See first topic for the instructions.
Thanks to mmon for the suggestion.

Hi, I have an Acer 7741G laptop (ATI Radeon HD 5470m, 1600x900 resolution, i5 sandy bridge), I installed iATKOS L2 (OSX 10.7.2), and I need help getting the proper video drivers for it.

When I first turn it on, it doesn't display video properly until I turn off GraphicsEnabler.  Once off, I can see video in 1024x768 only, the video is slow performance (as expected with non-proper/generic video drivers), and the OS says my graphics card is "display 3mb".


I tried following the two pieces of instructions in this link: http://www.osx86.net...on_hd_5470.html (editing instead "org.chameleon.Boot.plist" because that appears to be the OSX lion version of "Com.Apple.Boot.plist"), and it didn't seem to do anything, except for turning 'GraphicsEnabler' back on, which I afterwords disabled via boot loader options.

Good, so You need to find the correct configuration for the LVDS.


I never got EDID picked up without editing connector info for LVDS in ATI6000Controller.kext + GE=Yes / DSDT (PEGP) Patch


Changed:
Framebuffer name, because i'm using Ipomoea in ATI6000Controller.kext, bux_booga is using Osmunda, also VRAM size need to be changed accordingly and some other, you can compare below. (Crucial from here is the "Dual link" Patch, to have proper sleep function) Without the Dual Link Patch i am using transmitter 20 for LVDS (No sleep/wake), with the Dual Link Patch, i use transmitter 10 for LVDS and i get the sleep/wake function.

Added:
- A lot, but most of it it's just cosmetics. As i said, "ATI,bin_image" was crucial. Adding it to my PEGP + ATI6000Controller.kext with modified Ipomoea (LVDS transmitter 10) I got OS X to recognize my 6650M without GE=Yes and i have proper sleep/wake on my 7750G (and others, nai22, P.Gpunkt, E.Miller) on 10.7.0, 10.7.2, 10.7.3, 10.7.4, 10.8. with my kexts and my PEGP patch.

You need to find the right connectors info for all of the connectors: LVDS, HDMI, VGA.
Here is mine for 6650M:

0000000 02  00  00  00  40  00  00  00  09  01  00  00  10  01  00  03 --- LVDS
0000010 00  08  00  00  00  02  00  00  00  01  00  00  11  02  04  01 --- HDMI No audio
0000020 10  00  00  00  10  00  00  00  00  01  00  00  00  00  01  05 --- VGA
0000030

You can find some useful links in my OP and here http://www.insanelym...7042&st=120


You can choose between this or  GE=Yes (If your GC's SubsystemVendorID and SubsystemID are included in Chimera or Chameleon) after you find the correct connector info for LVDS
