3.3.2 EMS Mode Configuration
You
can
configure
the
RAM
3000 Deluxe
for
up
to
three
megabytes
of
RAM
memory
under
the
Lotus/In-
tel/Microsoft (LIM)
Expanded
Memory
Specification
(Version
3.20).
This
EMS
memory
is a special
type
of
memory
that
allows specially-written
software
to
access
program
data
far
larger
than
the
640KB limit imposed by
DOS.
To
configure
the
RAM
3000 Deluxe
for
EMS
mode, you
need
to
perform
the
following three-step process.
Step
One: Enabling EMS Mode
Before
enabling
the
EMS
mode
on
the
RAM
3000 Deluxe,
make
sure
the
contiguous
memory
space
defined
in
Section
3.3.1: Memory Configuration (Part
Three)
is less
than
the
amount
of
memory
chips installed
on
the
RAM
3000
Deluxe.
The
RAM
3000 Deluxe has two 110
ports
available
for
EMS
data
transfer;
since
each
EMS
I/O
port
accesses up to two
megabytes
of
EMS
memory,
enabling
both
EMS
110
ports
will allow access
of
up to
three
megabytes
of
EMS
memory
on
the
RAM
3000 Deluxe.
To
enable
the
EMS
I/O
ports, switch
OFF
either
SWl
position
5
(EMS
I/O
Port
1)
and/or
SWl
position
10
(EMS
I/O
Port
2).
(See
Figure
1
for
location
of
the
SWl
dipswitch).
