Recovering
from
a
BIOS
update
failure
The
blade
workstation
has
an
advanced
recovery
feature
that
will
automatically
switch
to
a
backup
BIOS
page
if
the
BIOS
code
in
the
blade
workstation
has
become
damaged,
such
as
from
a
power
failure
during
an
update.
The
flash
memory
of
the
blade
workstation
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
blade
workstation.
If
this
happens,
a
POST
message
Booted
from
backup
POST/BIOS
image
is
displayed.
The
backup
page
version
may
not
be
the
same
version
as
the
primary
image.
You
can
then
recover
or
restore
the
original
primary
page
BIOS
by
using
a
BIOS
flash
diskette.
To
recover
the
BIOS
code
and
restore
the
blade
workstation
operation
to
the
primary
page,
complete
the
following
steps:
1.
Download
the
latest
version
of
the
BIOS
code
from
http://www.ibm.com/
bladecenter/.
2.
Update
the
BIOS
code,
following
the
instructions
that
come
with
the
update
file
that
you
downloaded.
This
will
automatically
restore
and
update
the
primary
page.
3.
Restart
the
blade
workstation.
If
that
procedure
fails,
the
blade
workstation
might
not
restart
correctly
or
might
not
display
video.
To
manually
restore
the
BIOS
code,
complete
the
following
steps:
1.
Read
the
safety
information
that
begins
on
page
vii
and
“Installation
guidelines”
on
page
13.
2.
Turn
off
the
blade
workstation.
3.

the
blade
workstation
from
the
BladeCenter
unit
(see
“Removing
the
blade

on
page

4.
Remove
the
cover
(see
“Removing
the
blade
workstation

on
page

5.
Locate
the
BIOS
recovery
jumper
on
the
system
board
(see
“System

and
buttons”
on
page

6.
Move
the
BIOS
recovery
jumper
to
the
Closed
position
to
enable
the
recovery
mode.
7.
Replace
the
cover
and
reinstall
the
blade
workstation
in
the
BladeCenter
unit,
making
sure
that
the
media
tray
is
selected
by
the
