I'm new to writing assembly lang. programs on ms-dos machine and was wondering
if someone could answer a question.  Int 11 is supposed to return the
equipment configuration in the AX register.  However I can not seem to get
anything into this register.  When I write a 2 line debug routine as folllows:
-a100
-int 11
-int 20
and then look at the registers, AX is 0000.  Can someone give me some indication
of what I'm dong wrong?

I should mention that this program is being written on an IBM PC/AT, but it doesn't
work on an AT&T 6300 or 6300+ either.
