Subject:	Getting pre-interrupt registers under a DPMI hw interrupt?

I need to save all of the register values and the flag values that 
were their before the hardware interrupt occured.

Under real mode, I could just save all the registers, then get the 
correct values for flags, cs, and ip off of the stack.  Under DPMI, 
everything changes.  From the code that I have seen from CWS's DPMI,
the stack is changed (4k locked stack?) making ss and esp invalid, cs
and eip are obviously invalid, and some of the segment registers are
changed. (ds and es?).  I'm new to protected mode, and to DPMI, and
I have no idea how to get the values I need.  Do I need to use the
DPMI save-state functions?

p.s.  Sorry if you have seen this before.  I'm not sure if it get's posted
or not.  This news server seems a little flaky.
