ATI Raedeon HD 6870 seen as RaedeonHD NI40 on 10.6.8

[bangkok]

Mine is XFX Radeon HD 6870

I have the same problems

When cards show up as NI40 it means that there isn't a card specific ID in Chimera/Chameleon.

If you follow the directions in this topic: viewtopic.php?f=119&t=19330 and post your information I will add them to Chimera when I update it.

I just posted on that thread about my ASUS HD 6670. My device ID is in the 6xxx kexts, but I get the NI40 issue with framebuffer problems. I hope I posted enough info. Let me know

Thanks in advance MacMan

Do you use DSDT?

 

[kmmxracer]

Yes I use the DSDT from the database for my board

 

[Mr. Meoff]

as did I.

you can put

{
0x09,

{

}

Device (HDAU)

}

under Device (PCI0) in your DSDT
Name (_ADR, 0x00030000) Maybe the “3” is “1”?or others

I have exactly the same problem, but it seems to be working fine. I have the Sapphire HD6870 and I managed to update to 10.6.8 after 4 days of struggling!

If you guys find a solution please post it!

I was messing around, trying to fix my not being able to sign into the App Store issue when I discovered what makes this happen for me. If I have the following in my boot.plist I only get one DVI:

<key>PCIRootUID</key>
<string>1</string>

But if I don't have that in there the App Store doesn't work for me.

Also, having Graphics Enabler set to No will also give you the NI40.

Is there a guide to changing video cards on a working system?

I did a change from Geforce 8800 GTS to Sapphire ATI HD 6850 Toxic:

I just swapped the cards and boot up with chimera with GraphicsEnabler=No which starts
with 1024x 768 on both dvi's. Install new drivers with Multibeast.
Reboot and be ready!

Has anyone resolved this? I'm having the same issue. I boot with the option "GraphicsEnabler=No", but this results in my XFX Radeon 6870 showing as ATI Radeon HD NI40.

I unfortuntely don't have a 2nd monitor to (yet) to test if both DVI ports are working.
