Let's suppose your executable requires 33 Mb of memory to run.  When the
stub tries to allocate that much memory on the 48Mb system, it works.  When
it tries on the 32Mb system, it fails in the initial block allocation in
the stub and prints that error message.  Since W95 DOS boxes also may 
limit the DPMI memory, you can get the same failure message.

How much memory does the image require?  Does go32-v2 run ok on those systems?
You could pre-load cwsdpr0 before running go32-v2 to see how much memory
you have ...
