Dear Netters,

Does anyone know how much DPMI support there is in Windows standard mode
with EMM on?  I'm interested in accessing extended memory, possibly even
beyond the system physical memory (some I/O device memory that I have to
grab), and I use DPMI to get a selector to the extended memory.  Under
386 enhanced mode I have no problem accessing said memory, but with
Standard mode and EMM active Windows complains of a Page Fault at
the point where I dereference the selector.

Does anyone have similar experiences of what I had just described?
Anyway I can get at that memory without Windows coughing up and throwing
my program out?

Thanks in advance for any help you may have.

Regards,
C H Tan
