HARDWARE INSTALLATION
The
DOS Conventional
Memory is a linear memory which can be recogniz
ed
by DOS. The Extended Memory is also
a linear memory, but it is possible
to
run in protected mode from IM to 16M. The Expanded Memory is a “pag
ed”
memory mode, designed to
support EMS.
There
are
3 switches designed to set the on board RAM bank and memory
partition.
