You are quite corect in your statement. Connectix's Virtual product maps your
physical RAM to a virtual memory space. Thus, you aren't getting 14M ADDED to
the 8M of physical RAM... the extra 6M of address space is simply being used
to make it appear as though you had 14M ALTOGETHER. (Thus, only 8M of the 14M
can be present in physical RAM at one time.)
