Oh?  Are you referring to "real mode limit", or 32-bit  
implementations with
more than 32 address lines, or something else?

Either way, RMO is a really bad name for this, since that name is  
already
used for a similar but different concept.

Also, it seems you construct the physical address by masking out bits  
from
the effective address.  Most implementations will trap or machine  
check if
you address outside of physical address space, instead.
