[ Extenden to expanded memory ]
 
Well, with expanded memory there is a page of memory (mostly 64K) that
is paged into a certain location (below 1MB) with system calls. So to
use extended memory as expanded memory, you only need a driver which
switches do protected mode and copies 64K blocks from and to the
extended memory with the specified system calls.
 
Most RAM board manufacturers supply such a driver with their boards.
