@ neomatrix125: I'm,having the same problem, I can't seem to figure out what info i need from my bios either. I have read a dozen threads and can't seem to understand exactly how they derive the proper info. I too have spent a lot of time on this, especially read and learning as I am new to this. I am pretty new to Mac in general. Anyway hopefully some one can help us. I'm not asking for a hand out per say maybe just some guidance in the right direction. Thanks.

mucha already explain it at first post:-
B- Getting the ConnectorType, ATY,ControlFlags,Features, HotplugId and SenseLineId Values:
and
C- Getting the Encoder & Transmitter ID Values:

You can obtain SenseID from VBIOS, using radeon_bios_decode.0.2 tool which is available at bcc9's thread.

Per-"C- Getting the Encoder & Transmitter ID Values:", you can get Encoder & Transmitter using Dong's RadeonHD.kext.

Some experience dificulty when using Dong's RadeonHD.kext. So, I did explained here how to get RadeonHD dump using a simple script:-

and how to read RadeonHD dump:-

Thank you so much, as I said I'm very new to this so I'm trying to learn a lot at one time. That you for you quick reply, I know you do this in spare time. Thanks.

[neomatrix125]

When ever I load the RadeonHD.kext I get a KP
I tried removing the ATI drivers but it still KP's I managed to get it loaded once in Single user mode using various flags.
I just need a fairly descriptive way of how to load it properly and get the info that is provides!
When I fully understand I'm gonna be writing a full tutorial with script etc so it's easier for others!

EDIT: I've got my VBIOS already but I can't really find anything but the SenseID
EDIT2: Trying the RadeonHD.kext but it keeps stopping me from booting... Trying to load it post boot...

[kizwan]

When you get KP, it should tell you which kext causing it. Then you can remove that kext for a while. For RadeonHD.kext to work, boot with 32-bit mode.

[neomatrix125]

Ok, well I have been trying to boot with RadeonHD.kext and it hasn't crashed but I keep getting HFS Very Low Disk blah blah and it won't go ahead...
I've reinstalled and it just won't stop doing that -.-

Is the info I posted in post #536 not what I need? I can't get that script to give any info. It creates a file with nothing in it. Thank you

[kizwan]

Your log in post #536 doesn't contain any useful information at all. If the file is empty, that means RadeonHD.kext is not loaded.

[dajerm119]

I installed the kext and it let's me do my native resolution so I know it was loaded. But I will try again, and again and........ Until I get it. Thank you again

[neomatrix125]

I've been messing around with mine tonight and I've got somewhere different. I know pretty much most of the variables...
But my LVDS internal display stays with the apple logo and spinner still spinning! But the system is running as I can connect via LogMeIn! I don't know what to do O.o it's strange, what do I need to change to get that working properly???

[Lordadmiral Drake]

Can you post your dumps and the values you're using?

---

For my part, I now updated my OS X to 10.6.7 (non MBP 2011 update) and repatched ATIFramebuffer.kext. I still get corrupted screen with correct colors. I tried again to change feature flags from 09 to 00 but no luck. With that setting OS X crashed when switching to desktop (Black screen and CapsLock + NumLock LEDs blinking on my HP DV7)

Don't assume. Use "kextstat" command in terminal to confirm. If you can boot with RadeonHD.kext (meaning you can see the GUI), you don't need my script. It only for those who got blank+white corrupted screen. Did you use RadeonDump tool included with RadeonHD.kext to obtain the log?

[neomatrix125]

These are the values I am using and I've tried different things as well they all come up with the apple logo and spinning bit and it just sits on that. It's like the screen hasn't connected to the GUI part but it is stuck connected to the boot screen O.o
I am using the Uakari Personality and I have a 5650M and my laptop is a Dell 1749 with the 4 ports specified.

Boot in verbose mode -v
And tell us where it hangs

[neomatrix125]

It doesn't hang it boots and I can access it on LogMeIn...
Hmm i tried it now and the screen went black with no backlight -.-
I'll mess around with it later as I have to go out

Yes, i used the RadeonDump tool to get the log, that is the info I posted in #536. It didn't look like the dump info others were using that's why I asked if it was correct or not. With the RadeonHD.kext loaded I actually have a lot of choices for resolution, before I loaded it I was stuck on 1024x768. Now at native 1366x768. I will confirm it is loaded ,   Thank you.

[dajerm119]

I did "kextstat" and can confirm it is loaded.

[boombari]

Hi to all,

i need a help with my configuration.

I have an HP DV7-2215el with an ATI 4650 (94801002).

1) Installed Snow 10.6
2) Combo update 10.6.8
3) Mod of ATI4600Controller.kext and ATIRadeonX2000.kext to insert the 94801002 string in info.plist
4) Modify shrike personality in ATI4600Controller.kext with:


02 00 00 00 40 00 00 00 11 01 00 00 12 01 00 07
10 00 00 00 10 00 00 00 00 01 00 00 00 10 01 06
00 08 00 00 00 02 00 00 00 01 00 00 20 01 02 01


5) Patch my DSDT with Duallink patch, because my native resolution is 1600x900


Method (_DSM, 4, NotSerialized)
{
Store (Package ()
{
"AAPL01,DualLink",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}



6) Delete ALL ATI file except ATI4600Controller, ATIRadeonX2000(GA/GL/VA), ATIFramebuffer, ATISupport
7) Install Shrike Chameleon boot
8) Insert ATIROM dumped from Everest in EXTRA
9) Boot with GraphicsEnabler=Yes UseAtiVideoROM=Yes

RESULT:

LVDS show image with vertical white lines, colours are not correct, see flashing in some areas. As u can see in the attached files.
HDMI works good and show the secondary desktop
VGA works good and show the secondary desktop
In VNC the desktop is set to the correct resolution 1600x900 and works good ...without artifacts.

I try to extract EDID information from Windows, and put them into Overrides, but nothing changes

Can u help me ?

@Boombari, You have the same Encoder of 01 on port0 and port2.
This causes the display artifacts, try changing the encoder and experiment with different ones.

I have a problem with my Dell 1749, I have tried absolutely everything and I can't fault my info.

[Lordadmiral Drake]

I have the same setup as boombari. I noticed that unlike LVDS the image on HDMI is flawless. Nevertheless i'll try out changing HDMI to 00 and report back

EDIT: Changed encoder. Still corrupted screen
