Figured it out.  The main problem is not the DPMI, but the Win95 DPMI host.  
You can get up to 64 megs under Windows 95, but you have to do one thing, and 
remember one thing:  Do this: Set the DPMI memory settings for your DOS 
program to 65535 (You'll have to type it in manually).  Remember this: Windows 
won't let you allocate more than half of what's left (e.g, your largest memory 
block is limited to 32 megs, and after that, things keep getting cut off at 
the knees).
