How many video ports you have on the laptop and which connectorinfo you have tested for LVDS?

Have you tried some of the framebuffers in AMD7000Controller?

I have one VGA(D-SUB) and one Display port on my laptop. Still couldn't get correct screen.

What is the impact of having device id and subsystem id in Chameleon boot?

Not sure why but if I put my device id and subsystem id and use compiled boot file, it does not pickup the GPU even though I use GraphicsEnabler=Yes. It boots up just like GraphicsEnabler=No.

If I remove by device id or make it 0x000000 then it is showing white striped screen.

Thanks!

freeuser16 · June 22, 2013

If you have device id and subsystem id in Chameleon, theoretically GraphicsEnabler should work. If it still doesn't, you can try DSDT injection from the first post. Then device id's in Chameleon won't have any impact at all then, since you will boot with GraphicsEnabler=No.

Device id 6841 is in ATI6000Controller, so really no point in trying ATI7000. My card is also 7 series with device id in ATI6000Controller and it's working perfectly with it]

Thanks freeuser16,

Could you please share your ATI6000Controller.kext and boot file? Are you using boot+kext method for your 7670M?

freeuser16 · June 25, 2013

I'm using original ATI6000Controller (Clover bootloader patches it automatically) + DSDT injection (transferred to device-properties string to keep DSDT clean) to enable the card. But judging by your video BIOS, your card is much different.

What OS X version do you have? Could you post original ATI6000Controller from your system? I could patch it for you. Also post your original DSDT. There is something wrong with the one you posted before, it does not compile at all (> 200 errors).

ghajini08 · June 25, 2013

I need some help. I cannot dump my vga bios in GPUz. Here is my screenshot. I have been trying like mad to get this working. Is there any other way to dump the bios?

Trucker MK · June 25, 2013

Of course there is, but no one even bothers to read 5-10 posts back, it is already explained at least 3-4 times in the last 5 pages.

Trucker MK · June 25, 2013

@ deschutes

You said that with my kext you have working HDMI. This is confusing because i have senseID 0x1 for HDMI and you have SenseID 0x1 for LVDS in your VBIOS. I can't tell from your VBIOS which SenseID is for HDMI cause all other ports are Display Ports (SenseIDs 0x5 0x2 and 0x3 ) and one VGA (SeneID 0x8). Reinstall the vanilla ATI6000Controller.kext and try some of the framebuffers (Pondweed, Pithecia, Lotus, Ipomoea) with GraphicsEnabler=Yes and w/o AtiPorts=3 ( connect if you have VGA and HDMI) and use whatever boot file works for you. Find out which framebuffers works for VGA and HDMI so we can patch the right frambuffer. I'll patch one kexts for you with SenseID 0x1 for LVDS in different frambuffers so you can test all framebuffers with one kext. I also tried to compile your DSDT but it gives too many errors. In theory you should create Device (DGFX) in Device (PEGP) for your AMD, that's where the card is located.

Trucker MK · June 25, 2013

ATI6000Controller.kext.zip Here, if you are still on 10.8.3

Try these fraamebuffers:

Ipomoea

Cattail

Fanwort

Pondweed

P.S Sorry for the delay, I am enjoying my short vacation.

Oh man, @Trucker MK no need to get worked up. I have read every single post in this thread as have I read most of the other threads relating to the AMD 6490M. The problem, is in order to move ahead with it, I need to able to dump the bios, which as you can see from the screenshot.... does not happen. Nothing detects this card. GPUZ did not, neither did RBE. Neither did ATi Flash. I don't know if there are other methods out there, I am willing to try.

I have everything working on this laptop including Audio using the hd 3000 controller (the nodes are different than the probook series and that needed editing).

I just can't get it to work. I mean it shows up in system profiler, but no QE/CI. That is what I am aiming to do.

Please help me out ... am more than willing to do the needful work here. Any way I can dump using Linux?

This card relates to the fb Nomascus.

PS: Enjoy your mini vacation.

Trucker MK · June 26, 2013

Have you tried with AIDA64?

Or this way http://www.insanelymac.com/forum/topic/277042-ati-radeon-hd-6650m-graphics-enabler-dsdt-hdmi-audio-acer-aspire-7750g-2674g50mnkk/page-6?do=findComment&comment=1845018

Aida64 was the first thing I tried. It does dump a 64kb file. Upon using it with redsock bios decoder i get an error "ATOM signature not found". Obviously then the dump must be from the hd 3000.

I will try Phoenix and the RWeverything tonight itself and post the results here. Thanks for the info.

Trucker MK · June 26, 2013

Can you disable the HD3000 in the BIOS, cause if not, you probably wont be able to use the 6490M in OS X

ghajini08 · June 26, 2013

Sort of. I have options "Dynamic" and "Fixed" in my BIOS. I selected "Fixed" last night to test it out and Catalyst CC shows my "in use" card as AMD 6490M aka High Performance graphics card.

I am dumping my vbios using phoenix tool right now. However, I could not use the 1.42 version which is attached to your post. My hp bios file is a .bin file ...for eg mine is named as 01658.bin. It does not open with the 1.42 version. Did some digging and now I have version 2.14 which does the job just fine.

Here is the funny part. I end up getting 2 video rom files in the dump folder and an error saying I am using 64bit ..... will post a screenie in a while.

Trucker MK · June 26, 2013

Share the BIOS here, i wil try also to dump it.

ghajini08 · June 26, 2013

I found 3 files inside the dump folder that gave me a return on RBE. 2 of them came back as Whistler and one of them was Seymour. However all 3 of them gave me these 2 errors. The screenshots are attached. Am also attaching my bios to this post.

Ok, that is bad. What do I do now? Any ideas

Trucker MK · June 26, 2013

Well, since this option is not working, i am out of ideas too.

ghajini08 · June 26, 2013

Dang, I was so hoping to get this working. Thats the only thing missing. I got the card to even recognisse under system profiler by editing the ati6000controller.kext. Even got Clover to show it up with a firmware version.

The only problem is that it wont work with phoenix1.42. If only that bin file had been a .fd file.

Trucker MK · June 26, 2013

Try downloading older version of the BIOS.

ghajini08 · June 26, 2013

No problem, I will try that. I have all the older versions of this bios.

I'm using original ATI6000Controller (Clover bootloader patches it automatically) + DSDT injection (transferred to device-properties string to keep DSDT clean) to enable the card. But judging by your video BIOS, your card is much different.

Hi freeuser16, actually that was the reason why I couldn't try dsdt injection method. When I extract and just compile it without any modification, it gives me too many errors.

Not sure why pure dsdt extract cannot be compiled. I don't have dsdt loaded currently.

I am down to 3 errors with your DSDT, maybe i'll fix it after all.

Edit. Fixed it DSDTFixed.dsl.zip
