What does go32-v2 print when invoked with no arguments?

This might also be due to what BIOS reports.  Charles, can it be that the 
value in CMOS wraps around at 64MB and therefore CWSDPMI thinks it has 
fewer memory than actually available?  This is about a machine that has 
128MB physically installed.  Did you ever happen to run on such systems?
