You can set the chassis-intrusion detector switch inside the computer to alert the
network system administrator each time the computer cover is removed. For more
information about setting the chassis-intrusion alert, see Chapter 3, “Configuring
your computer” on page 21.
Component protection
Your computer has individual component serial numbers that can be registered with
a security company. You can also register the entire computer. By registering
computer components, you can improve the chances of identifying the components
if they are ever stolen and recovered. For more information about component
registration, go to the IBM Support page at
http://www.ibm.com/pc/us/desktop/assetid/ on the World Wide Web.
Data protection
You can lose data from the hard disk for a variety of reasons. Security violations,
viruses, or hard disk drive failures can all contribute to data loss. To help protect
against the loss of valuable information, IBM has incorporated the following
data-saving features in your computer.
SMART hard disk drive
Your computer comes with a self-monitoring and reporting technology (SMART)
hard disk drive that is enabled to report potential hard disk failures. If an error is
detected, a DMI-compliant warning message is sent to the monitor screen and, if
the computer is part of a network, to an administrator console. When an error is
detected, the data on the hard disk can be backed up and the drive replaced.
Virus protection
Your computer has built-in virus protection that can be enabled through the
Configuration/Setup Utility program. This built-in protection checks for viruses in the
boot record only. Also, Norton AntiVirus for IBM is available on the hard disk.
Integrated RAID capability
The integrated SCSI controller with RAID capabilities in your computer supports
redundant array of independent disks (RAID). You can use the LSI Logic
Configuration Utility program built into your computer to configure RAID level 1
(mirroring) for a single pair of attached devices.
Locking the keyboard
You can lock the keyboard so that others are unable to use it. If a user password is
set using the Configuration/Setup Utility program, the keyboard is locked when you
turn on the computer. You must type the password before the keyboard will unlock.
You can enable the user password feature with the Configuration/Setup Utility
program see “Using passwords” on page 24.
Some operating systems have a keyboard and mouse lock-up feature. See the
documentation that comes with your operating system for more information.
Updating system programs
System programs are the basic layer of software built into your computer. They
include the power-on self-test (POST), the basic input/output system (BIOS) code,
and the Configuration/Setup Utility program. POST is a set of tests and procedures
that are performed each time you turn on your computer. BIOS is a layer of
software that translates instructions from other layers of software into electrical
