You may need to update /etc/fstab of course, and any other settings that need to change along with the motherboard change, but other than that it should just work. > Or do I need to do a complete re-install/upgrade to the AMD64 > platform version of FreeBSD? If you want to run the AMD64 version, yes the BKM is a re-install. But you need not install the AMD64 version, the i386 version will run fine on the X2. > I'm not worried about memory usage past 4 GB (that's all we're installing), > or the slight (possible) increase in speed from using the native 64 bit > stuff. Then stick with i386. Your existing installation (assuming you've not used processor-specific CFLAGS to build world and/or ports) should work fine. Regards, Josh
