If something loads in upper memory with the NOEMS option and not without, 
it means that the EMS page frame eats up too much upper memory.  Although 
upper memory totals may look large enough in a memory report, the EMS page 
frame often makes the amounts discontiguous.    You need sufficient 
contiguous upper memory to load a single application.

Moving the EMS page frame to a different block of 64K upper memory may also 
work, although it has rules about the alignments allowed.
