Possible NVidia 8xxx/9xxx Solution for 10.6.3
Many people have had difficulty with getting their NVidia GPUs working with 10.6.2 and now 10.6.3. The issue seems to revolve around HDCP compatible displays. This would be all HDMI monitors and possibly newer DVI monitors. One workaround was to use two NVidia kexts from 10.6.1 along with EFI strings to enable the 8- and 9- series cards to work. Another simple solutions is to just use VGA monitors (no need for new kexts). See my previous post for our earlier solution for 10.6.2:http://www.insanelym...p...t&p=1346933
Many are now reporting issues with 10.6.3 with their 8xxx and 9xxxx series NVidia cards using HDMI/some DVI monitors with no solution. Others seem to have DVI monitors working, but have not confirmed to be HDCP DVI monitors. I have found one option I know to work with both HDCP-compatible DVI monitors and HDMI HDTVs.
Essentially, the solution is to use CruiSar's method with the latest AsereBLN bootloader. See his wonderful instructions on setting up an install using only fakesmc.kext and Realtek1000SL.kext with the new bootloader here:http://www.insanelym...p...t&p=1416253
Once you have his install method setup, it is important to remove any EFI strings for your GPU in your com.apple.boot.plist file. You also need to setup the "GraphicsEnabler" option. I would also recommend using the "EthernetBuiltIn" option as well. Here is the relevant snippet from com.apple.boot.plist:<key>GraphicsEnabler</key>
There is no need to use any older NVidia kexts anywhere, and you do not need to add your device IDs to any of the existing kexts. The magic happens with the CruiSAr's new method using a new bootloader (based of Chameleon RC4) that provides automatic EFI string injection and seems to offer better support for the NVidia GPUs in both 10.6.2 and 10.6.3.Once you have this setup, I can confirm that these setups work:
Single DVI monitor (HDCP capable)
Dual DVI monitors (both HDCP capable)
Dual monitors with one DVI monitor (HDCP) and one HDMI Sony 1080p HDTV (HDCP)
Single Sony 1080p HDTV (HDCP)
My current video card in an NVidia 9600 GT 512MB with Dual DVI outputs. To get HDMI, I used a DVI --> HDMI converter cable.
For anyone not using the Gigabyte EX58-UD5 but experiencing the same problem, I suggest using the GraphicsEnabler option from the AsereBLN_v1.1.9 Bootloader available here:http://github.com/as...eleon/downloads
Hopefully that helps alleviate some frustration. Please let everyone know if this method does or does not work for you.
