I posted this originally in the Windows section but to no avail, so I'm trying here.
I have a mac pro 1,1 and recently installed a 9800GT, which I flashed with an 8800 Mac bios. Things work great in OS X, but when I boot into windows 7 everything goes dead immediately, all video output dies.
However, if I plug in the x1900XT (original card) at the same time, install the nVidia drivers, and remove the X1900XT it will work fine during the boot, shows the windows logo, but dies when it gets to the login screen.
Also it boots perfectly in safe mode.
Any ideas?
