Power-On
Self-Test
After
power
is
turned
on
and
before
the
operating
system
is
loaded,
the
partition
does
a
power-on
self-test
(POST).
This
test
performs
checks
to
ensure
that
the
hardware
is
functioning
correctly
before
the
operating
system
is
loaded.
During
the
POST,
a
POST
screen
displays,
and
POST
indicators
display
on
the
virtual
terminal.
The
next
section
describes
the
POST
indicators
and
functions
that
can
be
accessed
during
the
POST.
POST
Indicators
POST
indicators
indicate
tests
that
are
being
performed
as
the
partition
is
preparing
to
load
the
operating
system.
The
POST
indicators
are
words
that
display
on
the
virtual
terminal.
Each
time
that
the
firmware
starts
another
step
in
the
POST,
a
POST
indicator
word
displays
on
the
console.
The
POST
screen
displays
the
following
words:
Memory
Memory

the

period
for

Keys
The
POST
keys,
if
pressed
after
the
keyboard
POST
indicator
displays
and
before
the
last
POST
indicator
(
speaker
)
displays,
cause
the
system
to
start
services
or
boot
modes
used
for
configuring
the
system
and
diagnosing
problems.
The
system
will
beep
to
remind
you
to
press
the
POST
key
(if
desired)
at
the
appropriate
time.
The
keys
are
described
as
follows:
1

The
numeric
1
key,
when
pressed
during
POST,
starts
the
System
Management
Services
(SMS)
interface.
5

The
numeric
5
key,
when
pressed
during
POST,
initiates
a
partition
boot
in
service
mode
using
the
default
service
mode
boot
list.
This
mode
attempts
to
boot
from
the
first
device
of
each
type
found
in
the
list.
It
does
not
search
for
other
bootable
devices
of
that
type
if
the
first
device
is
not
bootable.
Instead,
it
continues
to
the
next
device
type
in
the
list.
The
firmware
supports
up
to
five
entries
in
the
boot
list.
The
default
boot
sequence
is:
1.
Diskette
2.
CD-ROM
3.
Hard
file
4.
Tape
drive
(if
installed)
5.
Network
a.
Token
ring
b.
Ethernet
6
Key
The
numeric

works
like
the
numeric
5
key,
except
that
firmware
uses
the
customized
service
mode
boot
list,
which
can
be
set
in
the
AIX
service
aids.
