Power LED
The
Processor
Board
provides
support
for
an
external
power
LED
through
the
onboard
Motion/Power
LED
connector.
This
LED
is
controlled
through
the
SMC
37C935
GPIO
pins.
Once
the
SMC
chip
is
programmed
to
support
the
Power
LED
function
on
GPIO
pin
13,
the
LED
is
turned
“on”
anytime
all
power
to
the
Processor
Board
is
good.
The
system’s
power
management
software
has
the
option
to
turn
the
LED
off
indicating
the
system
is
in
a
power
‐
managed
mode.

MSR
interface
supports
a
maximum
of
3
tracks
of
magnetic

JIS
format
cards.
Activate
the
MSR
interface
by
enabling
it
in
BIOS
Setup
under
IO
Configuration.
The
MSR
interface
controller
is
a
memory
‐
mapped
device,
which
can
reside
at
system
memory
addresses
CA000,
CC000,
or
D0000.
If
MSR
capability
is
not
desired,
it
may
be
disabled
through
BIOS
Setup
.
Board BIOS
The
Processor
Board
uses
a
Phoenix
BIOS,
which
is
stored
in
Flash
ROM
and
easily
upgraded
through
the
network
connection
or
serial
port.
The
Flash
EEPROM
also
contains
the
Setup
utility,
Power
‐
On
Self
Tests
(POST),
and
APM

The
board
also
supports
system
BIOS
shadowing,
which
enables
the
BIOS
to
execute
from
onboard
write
‐
protected
DRAM.
The
BIOS
displays
a
sign
‐
on
message
during
POST
identifying
the
