Thanks Karel
I do have a USB drive attached.

It's a point which I think needs clarification on the web document I 
mentioned in another post.

When I started this, I actually thought I was writing to someone who had 
the power to fix the problem.

I've rechecked the page and now see I clicked the wrong link. I'm ccing 
doc in the hope the content of the page will be clarified.
