Yes, that was how I started when getting the box working - it proved that 
basic NTP and the network were both OK.  I actually synced with internal 
servers first as I hadn't got the gateway IP address configured on the 
FreeBSD box.

Oh, that's tiresome!  I haven't seen that problem, but as it happens on 
that box the GPS feed is simply a parallel RS-232 feed from a separately 
powered GPS puck.

Oh, that's quite nice.  I've not really tested that - I recall the power 
button really does kill the power, but next time I need to add a display 
to that box I can check.  It's very handy that the board powers up with no 
mouse, keyboard or display attached.

Enjoy your weekend!
