Thanks for the confirmation, nna2. I didn't have a USB around so I put the .ROM on a DVD and copied it to my computer, then just set the .ROM at the root drive. From there I was able to load it to the EZ Flash utility and it updated without an issue. When the system retarted after the Flash, I was greeted with the old, ugly looking AMI screen that said something about entering setup. That put me back in the UEFI BIOS. I just saved changes and exit, forcing a second reboot. That time the computer booted to windows.
