I don't know if this will help but when I had exactly the same problem with
an IBM PS/2 Model 80 I was told that as soon as installed memory exceeds a
certain level (2M for me) the system starts ROM shadowing.  This could be
what's happening to you people.  Shadowing isn't much use to me as I run 
SCO Xenix which ignores most of the system ROM.
