Ati HD6770m 6740:1002

@rohit11,


I enclose patched dsdt.aml to try.

There is also smbios.plist to put in extra.

Try GraphicsEnabler=No or Yes


Make copies of your own, if something goes wrong

We're screwed, :
with the rom .....!

is not your problem, but we can not do anything
would be useful to derive a custom connector framebuffer!

nVIDIA .....? You can post that too?

No matter now the framebuffer, I added the info to the dsdt, to see if it works INTEL HD3000

However, you can remove from your o.c.b.p AtiConfig and give these commands when you start Chimera:

-v AtiConfig=Cattail AtiPorts=4

Obviously you have to change the framebuffer, and the port number to test
To do this you must have in any case GraphicsEnabler=Yes in o.c.b.p

This is tedious , but it's the only way I know, I , I understand you had not tried to change the port

hey guys.If you have access to a macbook that comes with 6770 can you add the boot rom version,model identifier,SMproductname to your smbios.plist and try the switchable graphics?

 

[Micky1979]

In the meantime, I rebuild Chimera
(in Terminal for source, 1914 is a revision, change for new!)

svn co -r 1914 [url]http://forge.voodooprojects.org/svn/chameleon/branches/Chimera[/url]

,
with my subsystem id, and yet I'm trying.
To do this, I'm trying to knock out the Intel HD3000 in dsdt:

from this:
Name (_ADR, 0x00020000)

to this:
Name (_ADR, 0x00090000)

Change the address, one that does not exist, and obviously the HD3000 does not work!
I also added an false ID (0x17, 0x01, 0x00, 0x00) for added security (that does not work)

Trying different for ATI Framebuffer did not get a desktop, but many squares that change color if using Duckweed........................no idea

hope that Osx find available only Ati video card..........

Please, run this in Terminal:

ioreg -l | grep Mac

You can see our video card in some model identifier?

I think ....... iMac 12.1 or 12.2
(I'm in Windows now, I'm doing a job and can not get into OSX)

I think that's the right model identifier!

The iMac.rom is located on page 1 of this topic on Netkas forums link, but I do not know if this is OK, anyway here is attached

Another 6770m.rom, you can find on TechPowerUp,
but it is different from that of iMac
