Greetings, I've been trying to install fc3 - 64 bit on a Gigabyte GA-K8NPRO motherboard, with athlon 64 3000. It is, at best, not good. I keep gettin hangs at different places in the boot process. I was just wondering if anyone else on the list has installed 64 bit on with this motherboard? I've had the 32 bit version running on it with no problem.
