Maybe you have chosen some inconvenient addresses. Does the
application work if it does not access the saved memory sizes, just
uses the CMOS values? You mentioned previously that you were putting
the sizes at 1Mb and that it worked, what have you changed since then?
Make sure that your debug outputs are not corrupting things

I'm not sure what else I can suggest.
