As I mentioned, I tried the 2 modules both ways round
(in banks 1 and 2).

Yes, I did try this.
Actually, it had a rather frightening effect,
as I got a message telling me to press F1,
and when I did that I got the same message again.

However, pressing F2 got me back to the same situation as before.

I think my warranty has just run out,
so I can't ask Dell for an official explanation.

It's rather puzzling, but not really worrying,
as the machine appears to be working fine,
and the chance of it failing during my 3 weeks in Italy
seems fairly small ...
