6990m QE/CI, but no LVDS; need help with personality

12 posts in this topic

Recommended Posts

I have DVI fully working, but LVDS is not recognized. I am almost positive that it is assigned to port 0, and the senseid is correct. I've tried changing the control flags, but any changes and none of the graphics work. This also happens when I change the last two entries.

 

This is what I am currently using:

 

02 00 00 00 00 01 00 00 09 01 00 00 12 04 05 05 <-- LVDS, not recognized

00 04 00 00 00 02 00 00 00 01 00 00 10 00 03 03 <-- HDMI, not working, but it doesn't matter to me

04 00 00 00 14 00 00 00 00 01 00 00 11 02 01 01 <-- DVI, fully working as far as I can tell

00 04 00 00 00 01 00 00 00 01 00 00 21 03 02 02 <-- Not used/not sure what it is

00 04 00 00 00 01 00 00 00 01 00 00 22 05 04 04 <-- Not used/not sure what it is

 

Is there anything I'm doing blatantly wrong?

I forgot to mention, I had that, but the kext I was editing had them out of order and the ports matched the senseids so I thought maybe they had to match for this one. It is still recognized as being the correct port.

 

Since then, I've been working with Fanwort. LVDS is now recognized, but remains blank. av-signal-type is 0x0 if that means anything about the issue.

I've been messing with the transmitter and encoder, but so far no luck.

Just one thing,can you use your laptop screen?

The offset in the first post is taken from Elodea?

The only thing that I know is that with theese offsets(one of theese) you can use hdmi:

0000030	00  08  00  00  04  02  00  00  00  01  04  00  12  04  03  03
0000000	00  04  00  00  04  03  00  00  00  01  00  00  12  04  03  03

Can you upload your Ati6000Controller.kext?

Thanks

I'm now using:

 

02 00 00 00 40 00 00 00 29 05 00 00 10 00 00 05
00 08 00 00 04 02 00 00 00 01 04 00 12 04 01 03
04 00 00 00 14 00 00 00 00 01 00 00 11 02 02 01
00 04 00 00 04 03 00 00 00 01 00 00 21 13 03 02

 

DVI/HDMI working QE/CI but tearing occurs on both.

The LVDS does not work. It is recognized as a 17-inch spdisplays_display. Which is correct, but it stays blank.

Using Juncus Framebuffer & AtiPorts = 3

 

Edit:

I've looked at your other post now. I think our best bet is Osmunda. It seems to match quite closely what our cards are. Also where did you get the program that told you what the encoder, etc. was (the one you used before radeon_bios_decode)? Nevermind, I found it on a russian site. Unfortunately, it only confirms that what I had for the LVDS was actually correct so there must be some other issue. Maybe there just isn't any support until new framebuffers come out.

 

Chameleon does not seem to support Osmunda yet though. At least it doesn't appear in the source and I get an error when I set it.

I didn't understand one thing:can you use your laptop screen?

Probaly the transmitter value isn't correct,try with '51'

Nope.

It is recognised, but stays blank. LVDS is the type of connection the internal screen uses.

Why 51?

 

According to this bios decoder, it should be 10. I'll try it once I boot Lion back up. I've been using Windows the past few days.

I used moninfo on windows and the LVDS id was 51...also all the combinations with 10 that I have tried didn't work...

Hi,

 

I had the same issue with my LVDS. I solved it by installing dual link patch in my DSDT.

But you have to copy the code from GFX0 to PEGP and I had to set the decoder to 01 instead of 00.

 

This should work with all ATI 6XXX cards.

Please check your DSDT. search for PEGP and install the Duallink patch there.

should look like:

 

Scope (_SB.PCI0.PEG0.PEGP)

{

Method (_PRW, 0, NotSerialized)

{

Return (GPRW (0x09, 0x04))

}

Method (_DSM, 4, NotSerialized)

{

Store (Package (0x02)

{

"AAPL00,DualLink",

Buffer (0x04)

{

0x01, 0x00, 0x00, 0x00

}

}, Local0)

DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))

Return (Local0)

}

}

 

Then use your edited Kext and add the following to your Bootloader

 

GraphicsEnabler=Yes

AtiPorts=3

Aticonfig=%Your edited Framebuffer%

 

I Used Ipomoea

02000000 40000000 2901 0000 10 01 00 05 <-- LVDS

00080000 00020000 0001 0000 12 04 01 03 <-- HDMI

04000000 14020000 0001 0000 11 02 02 01 <-- DVI (not tested)

      Please help me with this 10.9.5 system. Motherboard: Gigabyte 965p-s3 rev3.3, gpu: Ati Radeon HD6450 (dvi/hdmi/vga). 
      Using any of the 3 ports on the 6450 (dvi, hdmi, vga), I see all the white letters on black background during boot but when they complete and it's time for the graphics to start I get a black screen and sometimes a restart after that. Using Clover 4411. Is there any way to get past this?

      Hi there.
      I'm new to this site but not totally new to hack. I've had a hack since 10.4 and the latest version I ran was 10.9, not totally fixed but it worked to what I needed. Now I want to make the machine run as good as it can. I can see there has been a lot of changes/upgrades/new solutions since I installed my hack and I have a hard time to catch up.  
      I've been able to boot and install macOSX and now I need the POST installation.
      I tried to install the clover EFI boot loader with these settings:
       
      and found the DSDT.aml and SSDT-0.aml from HERE
      found the apfs.efi
      and placed it in EFI -> EFI -> CLOVER -> driver64
      and these kext in here:

       
       
      But when I boot it up this is the first bootscreen I have. No partions, no mouse control, no nothing.

      if I exit clover this screen appear.

      and now everything works. 
       
      What is wrong?
      Cheers

      Hello,
       am running sierra on a optiplex 780 with a pny gt 710. I followed a step by step guide here. My machine boots fine and actually shows that the pny 710 is recognized I have attached a link with proof. My issue is when I am doing anything that relates to video it artifacts and slows alot. I understand that this is a cheap graphics card but from what I read online it seems like the other hackintoshes dont have this issue with this card. I am wondering if you have had any similar problems or solutions to this. I  also have attached my config file. I asked around on reddit and they said this could be related to the qe/ci. I am pretty new at this so I don't know how to enable this. I have installed the web drivers for 10.12.6 and that hasnt changed anything.
