The one time it happened to me, this did not work.  I can't find the 
details, but I think I had some other option set and I could not get 
into this.  I seem to recall the problem was the video option and driver 
for the DecTop that had the Anode chip.  For install, I even had to 
build a special iso with the proper drivers in.  But for a couple years, 
those DecTops were fun to play with.  One of the first fanless 
affordable systems; at the time I was working with a small group that 
was looking into a home server.  Something that is commodity now.

But I will remember this for the next time!

Oh, I recently pulled one out of the dustbin to put XP on it as a client 
test system.  Around here, I need to watch my pennies and I try to use 
what I have...
