Master Boot Record
Security
Allows you to enable or disable Master Boot
Record (MBR) Security.
When enabled, the BIOS rejects all requests
to write to the MBR on the current bootable
disk. Each time the computer is powered on or
rebooted, the BIOS compares the MBR of the
current bootable disk to the previously-saved
MBR. If changes are detected, you are given
the option of saving the MBR on the current
bootable disk, restoring the previously-saved
MBR, or disabling MBR Security. You must
know the setup password, if one is set.
Disable MBR Security before intentionally
✎
changing the formatting or partitioning of
the current bootable disk. Several disk
utilities (such as FDISK and FORMAT)
attempt to update the MBR.
If MBR Security is enabled and disk
accesses are being serviced by the
BIOS, write requests to the MBR are
rejected, causing the utilities to report
errors.
If MBR Security is enabled and disk
accesses are being serviced by the
operating system, any MBR change will
be detected by the BIOS during the next
reboot, and an MBR Security warning
message will be displayed.

Power-On Options
(continued)
Allows you to set:
• Option ROM prompt (enable/disable)
Enabling this feature will cause the system
to display a message before loading
options ROMs. (This feature is supported
on select models only.)
• Fan idle mode: The idle speed can be set
to 1 (default), 2, 3, or 4 (fastest). Higher
speeds will provide more cooling during
idle, but will be louder. (This feature is
supported on select models only.)
This feature allows you to increase the
✎
minimum fan speed; the maximum speed
is not affected and the fan cannot be
slowed below the minimum (1).
• Remote wakeup boot source (remote
server/local hard drive).
• After Power Loss (off/on): After power
loss, if you connect the computer to an
electric power strip and would like to turn
on power to the computer using the switch
on the power strip, set this option to “on.”
If you turn off power to the computer using
✎
the switch on a power strip, you will not
be able to use the suspend/sleep feature
or the Remote Management features.
• POST Delay (in seconds)
(enable/disable). Enabling this feature
will add a user-specified delay to the
POST process. This delay is sometimes
needed for hard disks on some PCI cards
that spin up very slowly; so slowly that
they are not ready to boot by the time
POST is finished. The POST delay also
gives you more time to select the F10 key
to enter Computer (F10) Setup.

Power-On Options
(continued)
Allows you to set:
• I/O APIC Mode (enable/disable).
Enabling this feature will allow Microsoft
Windows Operating Systems to run
optimally. This feature must be disabled
for certain non-Microsoft Operating
Systems to work properly.
•ACPI/USB Buffers @ Top of Memory
(enable/disable). Enabling this feature
places USB memory buffers at the top
of memory. The advantage is that
some amount of memory below 1 MB is
freed up for use by option ROMs. The
disadvantage is that a popular memory
manager, HIMEM.SYS, does not work
properly when USB buffers are at top of
memory AND the system has 64 MB or
less of RAM.
• Hot-Pluggable MultiBay Floppy
(enable/disable). Enabling this feature
allows you to hot-plug a MultiBay floppy
into a system running Windows 2000 or
Windows XP. (This feature is supported
on select models only.)
BIOS Wakeup Allows you to set the computer to turn on
automatically at a time you specify. (This
feature is supported on select models only.)
Onboard Devices Allows you to set resources for or disable
onboard system devices (diskette controller,
serial port, or parallel port).

PCI Devices • Lists currently installed PCI devices and
their IRQ settings.
• Allows you to reconfigure IRQ settings for
these devices or to disable them entirely.
These settings have no effect under an
APIC-based operating system.
Bus Options On select models, allows you to enable or
disable:
• PCI bus mastering, which allows a
PCI device to take control of the PCI bus.
• PCI SERR# Generation.
• PCI VGA palette snooping, which sets the
VGA palette snooping bit in PCI
configuration space; only needed when
more than one graphics controller is
installed.
• ECC support (some models) allows
hardware based error correction for
ECC-capable memories.

Device Options Allows you to set:
• Printer mode (bi-directional, EPP & ECP,
output only).
• Num Lock state at power-on (off/on).
• S5 Wake on LAN (enable/disable).
• To disable Wake on LAN during the off
state (S5), use the arrow (left and right)
keys to select the Advanced > Device
Options menu and set the S5 Wake on
Lan feature to “Disable.” This obtains the
lowest power consumption available on
the computer during S5. It does not affect
the ability of the computer to Wake on
LAN from suspend or hibernation, but will
prevent it from waking from S5 via the
network. It does not affect operation of the
network connection while the computer is
on.
• If a network connection is not required,
completely disable the network controller
(NIC) by using the arrow (left and right)
keys to select the Security > Device
Security menu. Set the Network
Controller option to “Device Hidden.” This
prevents the network controller from being
used by the operating system and reduces
the power used by the computer in S5.
• Hyper-threading (enable/disable).
• Processor cache (enable/disable).

Allows you to set:
• ACPI S3 support (enable/disable). S3 is
an ACPI (advanced configuration and
power interface) sleep state that some
add-in hardware options may not
support.
ACPI S3 selections are supported on
✎
select models only. If the ACPI S3
support option is not presented, the other
ACPI S3 options (ACPI S3 Video REPOST,
ACPI S3 Hard Disk Reset, and ACPI S3
PS2 Mouse Wakeup) will not be
available.
• ACPI S3 Video REPOST (enable/disable).
This feature reruns the video option ROM
on a boot from the S3 state (available on
select models only).
• ACPI S3 Hard Disk Reset
(enable/disable). Resets the hard disk
after waking from the S3 sleep state.
• ACPI S3 PS2 Mouse Wakeup
(enable/disable). Allows the mouse to
wake the system from the S3 sleep state
(available on select models only).
• Unique Sleep State Blink Patterns. Allows
you to choose an LED blink pattern that
uniquely identifies each sleep state.
• Frame Buffer Size (options vary
depending on platform). Allows you to
specify amount of system memory
dedicated to the embedded graphics
frame buffer. The AUTO setting attempts
to optimize the frame buffer size
depending on the amount of total system
memory.

Allows you to set:
• AGP Aperture size (options vary
depending on platform). Allows you to
specify the amount of system memory
reserved for use by the graphics controller.
• Monitor Tracking (enable/disable).
Allows ROM to save monitor asset
information.
• Spread Spectrum (enable/disable).
Allows system clocks to run with a spread
spectrum. (This feature is available on
select models only.)
•NIC PXE Option ROM Download
(enable/disable). The BIOS contains an
embedded NIC option ROM to allow the
unit to boot through the network to a PXE
server. This is typically used to download
a corporate image to a hard drive. The
NIC option ROM takes up memory space
below 1MB commonly referred to as DOS
Compatibility Hole (DCH) space. This
space is limited. This F10 option will allow
users to disable the downloading of this
embedded NIC option ROM thus giving
more DCH space for additional PCI cards
which may need option ROM space. The
default will be to have the NIC option
ROM enabled.
PCI VGA Configuration Displayed only if there are multiple PCI video
adapters in the system. Allows you to specify
which VGA controller will be the “boot” or
primary VGA controller.

Recovering the Configuration Settings
There are two ways to recover the Configuration Settings established
in the Computer Setup (F10) Utility.
Method One: Flash ROM CMOS Archive and Restore
Feature—Using Power Switch Override
F10 Computer Setup CMOS Configuration Settings are stored in
Non-Volatile RAM (NVRAM).
Each time the computer starts, the system ROM saves a copy of
NVRAM (including CMOS, passwords, and other system variables)
in the flash ROM. Should the system become unstable, the last known
good copy of NVRAM can be restored using a feature called “power
button override.” To restore NVRAM do the following:
1. With the unit powered down, press and release the power button.
2. Immediately after pressing the power button (during POST),
press and hold the power button until the unit powers down
(about four seconds).
At the next startup, the ROM detects this “power button override”
event and the backup copy of NVRAM is restored automatically.
Because of this feature, you cannot power off the computer with the
✎
power button immediately after powering up during POST
(Power-On Self-Test). The video display must be active before the
computer can be powered off by pushing the power button.
CAUTION: Unplugging the power cord during POST can corrupt the
Ä
splash screen (the logo screen seen during POST). Flashing the ROM is
required to restore the splash screen, although the computer will continue
to function normally.

Method Two: Save to Diskette and Restore from Diskette
This method of recovery requires that you first perform the Save to
Diskette command with the Computer Setup (F10) Utility before
Restore is needed. (See “Save to Diskette” on page 4 in the Computer
Setup options table.)
It is recommended that you save any modified computer
✎
configuration settings to a diskette, and save the diskette for possible
future use.
To restore the configuration, insert the diskette with the saved
configuration into the floppy drive and perform the Restore from
Diskette command with the Computer Setup (F10) Utility.
(See“Restore from Diskette” on page 4 in the Computer Setup
options table.)
