Hard-Disk Drive Sequence lists installed adapter cards and devices in the order they
will be initialized. The first hard-disk drive in the list becomes the bootable drive C.
%RRW6HTXHQFH
Boot Sequence enables you to set the order of the devices from which the system
attempts to boot.
The term boot refers to the systems start-up procedure. When turned on, the
system bootstraps itself into an operational state by loading into memory a
small program, which in turn loads the necessary operating system.
Boot
Sequence tells the system where to look for the files that it needs to load.
To set the boot device order, press <Enter> to access the fields pop-up options
menu. Use the up- and down-arrow keys to move through the list of devices. Press
<Enter> to enable or disable a device (enabled devices appear with a check mark).
Press plus <+> or minus <> to move a selected device up or down the list. The
following sections detail typical devices.
'LVNHWWH'ULYH$
Selecting Diskette Drive A: as the first device causes the system to try booting
from drive A first. If the system finds a diskette that is not bootable in the drive or
finds a problem with the drive itself, it displays an error message. If it does not
find a diskette in the drive, the system tries to boot from the next device in the
boot sequence list.

ACPI controls the operation of the systems Advanced Configuration and Power Inter-
face (ACPI) feature. The default is Off.
When ACPI is set to On, momentarily pressing the power button places the system in
a power-saving mode. To turn the system off completely, press the power button for
more than 4 seconds. When ACPI is set to On, interrupt request (IRQ) line 9 is not
available for use by an expansion card.
When ACPI is set to Off, momentarily pressing the power button turns off the system
completely. With this setting, IRQ9 is available for use by an expansion card.

Chassis Intrusion displays the status of the system chassis intrusion monitor and can
be set to Enabled, Enabled-Silent, or Disabled. The default is Enabled.
If the computer cover is removed while the intrusion monitor is set to
Enabled, the
setting changes to Detected and the following message is displayed during the boot
routine at the next system start-up:

If the computer cover is removed while the intrusion monitor is set to
Enabled-
Silent, the setting changes to Detected, but the alert message is not displayed during
the boot sequence at the next system start-up.
If the intrusion monitor is set to Disabled, no intrusion monitoring occurs and no mes-
sages are displayed.
To reset the Detected setting, enter the System Setup program during the systems
power-on self-test (POST). At Chassis Intrusion, press any edit key to reset the set-
ting, and then choose Enabled, Enabled-Silent, or Disabled.
NOTE: When the setup password is enabled, the setup password is required to reset
the Chassis Intrusion category.

The following subsections update the procedures for using a system password.
$VVLJQLQJD6\VWHP3DVVZRUG
Before you can assign a system password, you must enter the System Setup program
and check the System Password category.
When a system password is assigned, the System Password setting shown is
Enabled. When the system password feature is disabled by a jumper setting on the
system board, the setting shown is Disabled by Jumper. You cannot change or
enter a new system password if the Disabled by Jumper setting is displayed.
When a system password is not assigned, the System Password setting shown is
Not Enabled.
To assign a system password, follow these steps:
1. Enter the System Setup program and verify that the Password Status setting is
Unlocked.
For instructions on changing this setting, see Password Status in Chapter 2 of
your systems Reference and Installation Guide.
2. Highlight System Security and press <Enter>.
3. Highlight System Password and press <Enter>.
4. Type the desired system password in the Enter Password field and press
<Enter>.
You can use up to seven characters in your password.
As you press each character key (or the spacebar for a blank space), a placeholder
appears in the field.
The password assignment operation recognizes keys by their location on the key-
board, without distinguishing between lowercase and uppercase characters. For
example, if you have an M in your password, the system recognizes eitherMor m
as correct.
Certain key combinations are not valid. If you enter one of these combinations,
the speaker emits a beep.
