djfremen Posted December 6, 2012 Share Posted December 6, 2012 Hey everyone, I have a fully functioning xw8400 running 10.7.5 with full graphics support / LAN / Audio and even SAS controller. However, this one thing has been plaguing me: I can't boot without "arch=i386" thus making everything in Lion run in 32-bit mode. I have the Quadro fx 1500 and latest nVidia drivers. Anyone figured a way to boot 64-bit with older GeForce cards?
