Same issue as others.
I have managed to install 10.6.8, get audio working and get network functionality following a user guide. I even managed to run the userDSTD and reboot. Woo!
My card too was only appearing as n140 with Gigabyte 6870. I then found post suggesting to change my PCIRootUID to 1.
I restarted and then got black screen of death after white apple load window. Its seems like the system boots but I lose my screen functionality, im using the top DVI-I port with apple DVI to vga converter. Is this something anyone else has resolved. My card is in PCI slot 16x (first slot on board).
Does the card being seen as n140 actually matter? im confused as there is conflicting info on this post. Some say yes others no.
Experience so far:
Please help!
