 System is a fresh install on a 2008-Server Hyper-V VM. The /boot/loader.conf
 file setting for 2008 Hyper-V had not been loaded, because that is further
 down the script, and its only purpose is to turn off the fastide device.
 Pulling that in by hand and rebooting made no difference.
 I need to leave for awhile, but I will try to get a screen capture when I
 get back.
