v Date and Time Select this choice to set the system date and time, in 24-hour format (hour:minute:second). v System Security Select this choice to set a power-on password. See "Using passwords" on page 42 for more information about passwords. v Start Options Select this choice to view or change the start options. Changes in the start options take effect when you start the blade server. - Startup Sequence Options Select this choice to view the startup device sequence that is set for the blade server. Note: To set the startup sequence, which is the order in which the blade server checks devices to find a boot record, you must use the management-module Web interface. You can set keyboard operating characteristics, such as whether the blade server starts with the keyboard number lock on or off. You can enable the blade server to run without a diskette drive or keyboard. You can enable or disable the PXE option for all of the Ethernet controllers in the blade server. The default settings enable the PXE option for the two Ethernet controllers on the system board. If you enable the boot fail count, the BIOS default settings will be restored after three consecutive failures to find a boot record. You can enable a virus-detection test that checks for changes in the boot record when the blade server starts. v Advanced Setup Select this choice to change settings for advanced hardware features. Important: The blade server might malfunction if these settings are incorrectly configured. Follow the instructions on the screen carefully. - Memory Settings Select this choice to manually enable a pair of memory connectors. If a memory error is detected during POST or memory configuration, the blade server automatically disables the failing memory pair of memory connectors and continues operating with reduced memory. After the problem is corrected, you must enable the memory connectors. Use the arrow keys to highlight the pair of memory connectors that you want to enable, and use the arrow keys to select Enable. To maintain optimum system operation in the event of a memory failure, you can set memory configuration to mirroring or sparing. Memory mirroring stores duplicate data on two DIMMs to prevent data loss if a DIMM fails. Memory sparing removes the failed memory from the system configuration and activates a hot spare memory pair of DIMMs to replace the failed memory pair of DIMMs. Before you can enable the memory mirroring or sparing, at least two pairs of DIMMs must be installed in the blade server that adhere to the special requirements that are described in "Installing memory modules" on page 22. Set Memory Configuration to Flat to disable memory mirroring and sparing. Note: Memory mirroring is available only when an optional IBM BladeCenter Memory and I/O Expansion Blade is installed on the blade server. Chapter 4. Configuring the blade server 41

Startup
Sequence
Options
Select
this
choice
to
view
the
startup
device
sequence
that
is
set
for
the
blade
server.
Note:
To
set
the
startup
sequence,
which
is
the
order
in
which
the
blade
server
checks
devices
to
find
a
boot
record,
you
must
use
the
management-module
Web
interface.
You
can
set
keyboard
operating
characteristics,
such
as
whether
the
blade
server
starts
with
the
keyboard
number
lock
on
or
off.
You
can
enable
the
blade
server
to
run
without
a
diskette

You
can
enable
or

the
PXE
option
for
all
of
the

Memory
Settings
Select
this
choice
to
manually
enable
a
pair
of
memory
connectors.
If
a
memory
error
is
detected
during
POST
or
memory
configuration,
the
blade
server
automatically
disables
the
failing
memory
pair
of
memory
connectors
and
continues
operating
with
reduced
memory.
After
the
problem
is
corrected,
you
must
enable
the
memory
connectors.
Use

To
maintain
optimum
system
operation
in
the
event
of
a
memory
failure,
you
can
set
memory
configuration
to
mirroring
or
sparing.
Memory
mirroring
stores
duplicate
data
on
two
DIMMs
to
prevent
data
loss
if
a
DIMM
fails.
Memory
sparing
removes
the
failed
memory
from
the
system
configuration
and
activates
a
hot
spare
memory
pair
of
DIMMs
to
replace
the
failed
memory
pair
of
DIMMs.
Before
you
can
enable
the
memory
mirroring
or
sparing,
at
least
two
pairs
of
DIMMs
must
be
installed
in
the
blade
server
that
adhere
to
the
special
requirements
that
are
described
in
“Installing
memory
modules”
on
page
22.
Set
Memory
Configuration
to
Flat
to
disable
memory
mirroring
and
sparing.
Note:
Memory
mirroring
is
available
only

an
optional
IBM
BladeCenter
Memory
and
I/O
Expansion
Blade
