Recovering
the
BIOS
code
If
the
BIOS
code
has
become
damaged,
such
as
from
a
power
failure
during
a
flash
update,
the
blade
server
might
appear
to
be
nonfunctional
(no
video,
no
beeps).
You
can
recover
the
BIOS
code
using
the
BIOS
code
page
jumper
(J1E2)
and
a
BIOS
flash
diskette.
Note:
To
obtain
a
BIOS

The

a
primary
page
and
a
backup
page.
The
J1E2
jumper
controls
which
page
is
used
to
start
the
blade
server.
If
the
BIOS
code
in
the
primary
page
is
damaged,
you
can
use
the
backup
page
to
start
the
blade
server;
then,
start
the
BIOS
flash
diskette
to
restore
the
BIOS
code
to
the
primary
page.
To
recover
the
BIOS
code,
complete
the
following
steps:
1.
Turn
