The HIMEM.SYS which came with DOS6.2 and earlier was limited to
64Mb of memory.  Later versions with Win9x have an extended API
that will support it all.

What version of CWSDPMI do you have? (cwsdpmi -u should say)
How much memory does GO32-V2 report?  How did you determine how
much memory was available (if it was small allocations, read the
FAQ and/or CWSDPMI documentation to increase internal stack).
