Owner`s manual
If
you have a CS8220-based A T motherboard with 512KB base
and 512KB extended memory installed:
You
choose
the
"640K"
option
from
Table
12;
switch SW3
positions 6
and
8 ON.
This
will upgrade base
memory
from
512-640K
(BOOOOH-9FFFFH)
and
upgrade
extended
memory
from
1536K (180000H).
If
you have 7680KB
of
extended memory already installed in your
system:
You choose
the
"512K"
option
from
Table
12
and
the
'7
Mil
option
from
Table
13;
switch SW3 positions
3-6
ON.
This
will upgrade
extended
memory
from
7680K (780000H).
NOTES:
1.
A void configuring SW3 so it will result in starting ad-
dresses
of
768K
(COOOOH)
and
896K
(EOOOOH);
these ad-
dresses
are
reserved for system memory use. The
"640K"
position from Table
12
is ONLY
for
CS8220-based AT
motherboards
that
split
S12KB
base
and
S12KB
extended
memory on the motherboard.
2.
Make sure you have
at
least
S12KB
of base memory in-
stalled in your system,
or
your system will not
be
able to
access extended memory space.
