Aha - OK, thanks.

When I last saw this it did have RUNNING in about the middle.

I tried putting them in and it worked - I sent an earlier email
describing this.

I have no idea either! It's like it just started working in the last
of several 12.04 boots. Is there some kind of repair/fix process at
boot time? I've had this kind of thing happen on win boxes - after a
couple of boots, it starts working.

Now running 14.04, continuing the prep. It's looking pretty good - may
change over even if 12.04 gets running well. I have 12.04 on one disk
and 14.04 on another. Is there a way I can put both in the box and
easily [not via the bios :-) ] select which one to boot from?

I'll try the above suggestions and send the above when I boot 12.04...

Many thanks for the help!
