Recovering
from
a
BIOS
update
failure
The
server
has
an
advanced
recovery
feature
that
will
automatically
switch
to
a
backup
BIOS
page
if
the
BIOS
code
in
the
server
has
become
damaged,
such
as
from
a
power
failure
during
an
update.
The
flash
memory
of
the
server
consists
of
a
primary
page
and
a
backup
page.
If
the
BIOS
code
in
the
primary
page
is
damaged,
the
baseboard
management
controller
will
detect
the
error
and
automatically
switch
to
the
backup
page
to
start
the
server.
If
this
happens,
a
POST
message
Booted
from
backup
POST/BIOS
image
is
displayed.
The
backup
page
version
might
not
be
the
same
as
the
primary
page
version.
You
can
then
recover
or
restore
the
original
primary
page
BIOS
by
using
a
BIOS
flash
diskette.
Note:
To
create
and
use
a

you
must
add
an
optional

drive
to
the
server.
