Hi Chris, 
Thank you very much for the screenshots!!!

On the host there is a 1MB LoaderData memory range, which splits
the big Conventional Memory range into a small one (15MB) and a
big one: the small one is too small to hold the staging area.

I'm going to post a patch shortly.

For people who are interested in the details: please see

Thanks,
