>>From looking at the code it seems to me that StartImage is called from
TPL_CALLBACK.
According to the Spec StartImage can only be called from <TPL_CALLBACK.

If the current code actually works it means that there are at least 3
problems that should be addressed:
- call StartImage from TPL_APPLICATION
- ASSERT the tpl in LoadImage and StartImage
- ASSERT the tpl in ExitBootServices

Thanks
Michael
