The

is a 32-bit
CPU
with
a
16-bit

and
a

external

2-3
GENERAL
FEATURES
capability
of
the
386SX
CPU
allows
simultaneous
execution
of
applications
from
multiple
operating
systems
such
as
MS-DOS
and
UNIX.
80386SX
is
not
only
an
enhanced
version
of
80286,
but
designed
to
overcome
the
deficiencies
of
80286.
It
allows
you
to
make
use
of
application
software
that
a
286
just
can't
handle.
For
example,
a
very
important
attribute
of
any
multi-tasking/multi-user
operating
system
is
its
ability
to
rapidly
switch
between
tasks
or
processes.
The
386SX
Microprocessor
directly
supports
this
operation
by
providing
a
task
switch
instruction
in
hardware.
The
386SX
Microprocessor
has
two
modes
of
operation:
Real
Address
Mode
(Real
Mode),
and
Protected
Virtual
Address
Mode
(Protected
Mode).
Real
Mode
has
the
same
base
architecture
as
the
8086,
but
allows
access
to
the
32-bit
register
set
of
the
386SX
Microprocessor.
The
complete
capabilities
of
the
386SX
Microprocessor
are
unlocked
when
the
processor
operates
In
Protected
Virtual
Address
Mode.
Protected
Mode
vastly
increases
the
linear
address
space
to
four
gigabytes
and
allows
the
running
of
virtual
memory
programs
of
almost
unlimited
size.
In
addition,
Protected
Mode
allows
the
386SX
Microprocessor
to
run
all
of
the
existing
386DX
CPU,
80286
and
8086
CPU's
software,
while
providing
a
sophisticated
memory
management
and
a
hardware-assisted
protection
mechanism.
(J
Protected
Mode
allows
the
use
of
additional
instructions
specially
optimized
for
supporting
2-4
multitasking
ol)crating
SystClll.
The
380SX
Microprocessor
also
urrers
ruur

are
optimized
to
support
a

the

GENERAL
FEATURES
MATH
COPROCESSOR
The
demand
for
sophisticated,
number-
crunching
scientific
and
business
applications
has
rapidly
increased
in
recent
years.
80386SX
features
an
integer
Arithmetic
Logic
Unit
which
only
handles
simple
integer
operations
such
as
addition
and
multiplication.
Floating-point
operations
which
are
actually
utilized
by
applications
must
be
accomplished
through
software
routines.
To
overcome
this
obstacle,
external
Math
coprocessor
is
necessary.
The
Math
coprocessor
contains
complex
hardware
and
la~ge
data
registers
for
floating-point
numeric
operations.
The
387SX
Math
CoProcessor
is
an
extension
to
the
Intel
386
microprocessor
architecture.
The
combination
of
the
387SX
with
the
386SX
Microprocessor
dramatically
increases
the
processing
speed
of
computer
application
software
which
utilizes
mathematical
operations.
This
makes
an
ideal
computer
workstation
platform
ror
applications
such
as
financial
modelling
and
spreadsheet,
CAD
IC
AM,
or
gra
ph
ics.
The
387SX
Math
CoProcessor
adds
over
seventy
mnemonics
to
the
386SX
Microprocessor
instruction
set.
Specific
387SX
math
operations
include
logarithmic,
arithmetic,
exponentional,
and
trigonometric
functions.
The
387SX
supports
integer,
extended
integer,
floating
point
and
BCD
data
formats,
and
fully
conforms
to
the
2-6
GENEHAL
FEATUHES
ANSI/IEEE
floating
point
standard.
The
math
coprocessor
offloads
the
complicated
math
functions
from
the
CPU.
Therefore,
it
handles
in
one
instruction
what
would
have
required
many
steps
with
the
CPU.
So
you
can
save
time
on
your
favourite
spreadsheet,
database,
engineering,
scientific
and
graphics
packages.
The
387SX
CoProcessor
is
object
code
compatible
with
the
387DX
and
upward
object
eode
compatible
from
the
80287
and
8087
Math
Co-processors.
In
real-address
mode
and
virtual-8086
mode,
the
386SX
Microprocessor
and
387SX
Math
Coprocessor
is
completely
upward
compatible
with
software
for
the
8086/8087
and
80286/80287
real-
address
mode
systems.
In
protected
mode,
the
386SX
Microprocessor
and
387SX
Math
Coprocessor
is
completely
upward
compatible
with
software
for
the
80286/80287
protected
mode
system.
In
all
modes,
the
386SX
Microprocessor
and
387SX
Math
Coprocessor
is
completely
compatible
with
software
for
the
386
Microprocessor./387

Coprocessor

Interleave
Operation
Two-way
interleaving
is
automatically
enabled
whenever
both

If
all

four-way
interleaving
automatically
occurs.
If
the
four

are
not
populated
with

DRAMs,
two-way
interleaving
occurs
on
pairs
that
are
of
the

In a system

I/O
SlJBSYSTEl\1
It
IS
vcry
important
that
a
high
speed
system
should
be
compatible
with
existing
peripherals
without
downgrading
the
perrormance.
The
Panther-II
system
is
exactly
designed
with
this
capability
in
mind.
To
be
compatible
with
the
existing
add-on
cards,
user
has
the
option
of
defining
the
I/O
speed.
If
for
example,
the
peripheral
card
is
not
capable
of
operating
at
high
speed,
user
can
define
a
slow
speed
for
I/O
slot
operation

CONFIGURATION
Four
DIP
memory
banks
and
two
SIMM
memory
banks
are
available
on
Panther-II,
these
memory
banks
arc
designated
as
BANK
0
to
BANK
3
in
the
Illotherboard.
User
has
the
option
or
either
uSing
DIP
type
DRAM
or
SIMM
type
memory
modules.
Still
if
the
user
prefers,
he
could
usc
both
types
together.
That
means
you
could
make
usc
of
DIP
and
SIMM
type
memory
simultaneously.
Please
note
that
however,
you
cannot
install
both
memory
types
marked
with
the
same
bank
reference.
For
example
if
you
had
already
installed
DIP
memory
into
'BANK
0',
you
can
no
longer
install
SIMM
into
the
memory
modules
referenced
as
'BANK
0'.
One
bank
of
memory
rerers
to
2
SIMM
modules
or
6
DIP
memory
chips
(4x44256
+
2x41256).
For
the
SIMM
memory,
user
can
install
256K,
1M
or
4M
SIMM;
therefore
it
has
a
maximum
memory
capacity
of
16
Megabytes.
On
the
other
hand;
if
purely
DIP
DRAM
are
used,
it
will
allow
up
to 2 Megabytes
of
memory.
The
DIP
DRAM
are
organized
in
4
banks
as
shown

In
normal
situation,
those

and

Hence,
the
user
can

unpopulated

thus
allowing
you
to
minimize
the
system
cost.
There
are
several
combinations
of
DRAM
types
you
may
consider.
So, a basic
system
can
be
equipped
with
fewer
memory
and
later
more
memory
can
be
added
when
upgrading
the
system.
As

Installing
SIMM
Modules
Whenever
adding
memory
modules
to
the
motherboard,
install
2
modules
at
a
time.
Also
make
sure
that
the
SIMM
is
installed
in
the
correct
orientation,
the
RAM
chips
on
the
modules
should
be
facing
the
I/O
slot.
See
the
figure
on
next
page
for
illustration.
To
install
a
module,
the
module
edge
should
angled
into
the
socket's
contact
and
then
the
module
is
pivoted
into
position,
where
the
locking
latches
will
secure
it.
If
the
module
edge
is
not
completely
inserted
into
the
socket,
it
cannot
be
pivoted
to
be
in
vertical
position
and
should
be
dragged
out
and
inserted
again.
Do
not
force
the
module
into
the
SIMM
sockct.
It
will
damage
the
locking
latches.
The
modules
should
be
locked
by
the
locking
latches
of
the
sockets
firmly.
Please
check
carefully
before
turning
on
the
power.
Otherwise,
the
system
will
not
work
properly.

There
are
47
types

supported
by

BIOS.
Consult
your
fixed
disk
manual
to
determine
its
correct
type.
The
parameters
such
J
as
cylinder
number,
head
number,
sector
number
and
pre-compensation
must
match
your
fixed
disk's
parameters.
Use
PgUp
and
PgDn
keys
to
change
the
fixed
disk
type.
If
the
type
of
your
fixed
disk
is
not
included
in
the
hard
disk
list,
define
a
new
type
as
type
47.
Use
left
and
right
arrow
keys
to
move
between
the
parameter
fields
and
enter
the
parameters.
The
parameters
will
be
stored
in
the
CMOS
RAM
and
your
fixed
disk
can
be
used
afterwards.
Each
hard
disk
can
be
assigned
a
different
type

hard
disk.
So

System

If
the
type
of
fixed
disk
is
wrong,
it
takes
a
while
before
the
BIOS
can
identify
the
error.
__
After
setting
the
fixed
disk
type,
if
the
system
haIts
after
reboot,
please
wait
for
a
while.
It
is
most
likely
that
the
setting
of
fixed
disk
type
is
incorrect.
When
you
install
a
new
hard
disk,
make
sure
whether
it
is
already
formatted.
If
not,
the
BIOS
has
to
check
for
a
while
before
reporting
the
ha
rd
disk
error.
In
fact,
the
error
arises
only
because
the
hard
disk
is
not
formatted.
If
the
hard
disk
is
formatted,
you
can
run
DOS
FDISK
and
DOS
FORMAT.
Some
fixed
disks
are
specially
handled
and
must
be
set
to
'Not
