MacPro4,1 crashes after GraphicUpdate with PC 5870

[Elphiel]

Hi there!

I have a Problem after installing the recendly released Snow Leopard Graphics Update. I own a 2009 quad Mac Pro and use the default GT120 for my everyday OS X and a additional PC Sapphire 5870 for Bootcamp gaming. Runs great normaly but after the Graphics Update i cant boot into OS X anymore with both Cards installed. While booting i get a greyed out screen and a Message that i schould hold down the Power Button and restart the system. No problems at all in Windows and if i uninstall the 5870 i can boot into OS X without any problems.

I never tried to flash the Card or manipulate anything about the graphics on OS X. I also completly reinstalled the Update without the 5870 plugged in. Still cant boot with both cards into OS X anymore.

Any ideas besides a complete reinstall of OS X?

Thanks for your help!

flash the card

looks like the best solution now. Just used the last 2 hours reading around about flashing and joined the netkas forum crew. Think i give it a try in the evening.

Use the latest Zeus Tool Flasher and run the patch, reboot and voila.
