Updating
BIOS
code
The
BIOS
code
can
be
updated
by
using
an
external
USB
diskette
drive
or
by
using
a
Linux
or
Windows
®
update
package
(if
available).
The
most
current
level
of
BIOS
code
for
the
server
is
available
at
http://www.ibm.com/support/.
After
you
make
sure
that
the
server
has
the
latest
level
of
baseboard
management
controller
firmware,
you
can
update
the
BIOS
code
for
the
server
through
one
of
the
following
methods:
v
Downloading
the
latest
BIOS
code
from
the
IBM
Web
site,
creating
an
update
diskette,
and
using
an
external
USB
diskette
drive
to
install
the
BIOS
code.
v
Installing
an
update
package
for
the
Linux
or
Microsoft
®
Windows
operating
system,
if
available.
If
power
to
the
server
is
interrupted
while
the
POST/BIOS
code
is
being
updated
(flash
update),
the
server
might
not
restart
correctly
or
might
not
display
video
(no

use
the
following
procedure
to
recover:
1.
Read
the
safety
information
that

and
place
it
on
a
flat,
static-protective
surface;
then,
remove
the
cover.
3.
Locate
the
boot
block
recovery
jumper
(JP4
on
the

on
page
4).
4.
Move
the
boot
block
recovery
jumper
from
pins

the
server
to
the
power
source,
keyboard,
monitor,
and
mouse.
7.
Insert
the
POST/BIOS
update
(flash)
diskette
into
the
diskette
drive.
You
can
download
a
file
to
create
this
diskette
from
http://www.ibm.com/support/.
8.
Turn
on
the
server
and
the
monitor.
9.
After
the
update
session
is
completed,
turn
off
the
server
and
monitor.
10.
Remove
the
diskette
from
the
diskette
drive.
11.
Disconnect
all
power
cords;
then,
remove
the
server
cover.
12.
Return
the
boot
