It still doesn't work. I get a quick grey flash, then a black screen. I think it may have something to do with port detection......I am not sure. I need dev input here.

I booted with both IGP and ATI enabled, by default it uses IGP, so I ran BDMESG. log attached below:

sorry nope, i'd need a boot of just the ati and not on the igp. but 6990 in general isn't supported via the ati6000 controller. Some have gotten it working. I dont' know if the 6990m is a totally different beast or not.. but you'd have to boot into -s using the 6990 and not the IGP to get teh correct bdmesg

Ok I will be getting you one immediately in just ATI mode. Just to clarify some things: 1.This is a MOBILITY 6990, not a desktop 6990. The cores are different. The Mobility 6990 is like a desktop 6850/6870 2. The device ID's for 6970m and 6990m ARE EXACTLY the same. Thus, theoretical support should exist natively in ati6000controller. I have seen the device ids myself in there. The 6970m is in the current imac, the 6990m is not. however, both cards are the same dev and vendor ids. again, I will get you an ATI-Only bdmesg ASAP.

OK. I managed to get a BDMESG of just my ATI card, with graphicsEnabler=no Attached below. please advise.

If using the intel, probably the problem is this http://www.tonymacx86.com/viewtopic.php?f=15&t=28851 Try to patch it as it state. Carefull. if you have already that method, you need to change it and update it.

Hi everyone, @Cosmosis Jones Possible add in chameleon 2 cards ? Only chimera 1,7 detected out of box the 2 cards same time Video Card : Intel(R) HD3000 Mobile Dev ID 0116: Ven ID 8086, Ati HD6770m 2GB Gddr5 Dev ID 6740:Ven ID 1002. Because now impossible update bootloader,use the old version of chimera 1,7 1459. Other problem for me 17 inch screen boot chameleon résolution is bad :1024*768 the résolution correct is 1600*900 this problem is bootloader ? Possible resolved this problems ?

So the dsdt patch just adds the "AAPL00,DualLink", .. gma.c could include .. but the issue still is 2 cards booting.. thats why the dsdt patch works, but chameleon won't.. i think netkas got something working by trying to do this: in chameleon use graphics enabler for intel. set intel as boot display. use AtiROM for the ati card.. i dunno

Comment 15 by Applehacker, Feb 22, 2012
Ok I post the full results of my experiment: ATI GPU only results in only black screen, regardless of ATI.rom or ge=yes. Something is wrong with the way the LVDS is encoded in the ATI6000Controller.kext I don't think chameleon will be able to solve this, only a DSDT to kext mod will do it. Intel IGP works with GE so long as we have dual-link patch in the DSDT. This is an LVDS issue i'm pretty sure. If I hook up my HDMI in to my HDMI out, we get a display on the laptop screen. Something is not sending properly to LVDS. Any more ideas?

Comment 16 by Cosmosis Jones, Feb 22, 2012
well open a new issue w/ the intel IGP for adding that dual link. dual link is added for device x3100 what is the device id pci id/ venid for yours. we need to add that to gma.c but that isn't part of this issue.

Comment 17 by Applehacker, Feb 22, 2012
This thread is for 6970m/6990m only. IGP is easily fixed, just add dual link patch.... its literally copy and paste. Any thoughts on 6970m/6990m?

Ok, But new version chameleon detected intel hd 3000 "intel unknown"i boot with graphicsenabler=yes i assume the DevID and VenID not insert totally in chameleon. Possible insert Definetely the DevID and VenID of the 2 cards please ? HD3000 Mobile Dev ID 0116: Ven ID 8086 HD6770m Dev ID 6740:Ven ID 1002. Thanks advance Cosmosis.

Comment 19 by Applehacker, Feb 22, 2012
Intel is auto detected...... as of version 1.6, so I have no idea what you are talking about. I get Intel HD 3000 when using chimera 1.7, so unless you have weird dev ids, it should definitely work for your, or your BIOS settings are wonky.

What fix was applied, and where can we download the fixed bootloader?
