2-10 Dell OptiPlex GXi Low-Profile Systems Reference and Installation Guide
USB
USB determines whether the Universal Serial Bus (USB)
connectors on the system board are turned ON or OFF (the
default). You must reboot your system before a change
takes effect.
Speaker
SPEAKER determines whether the onboard speaker is ON
(the default) or OFF . A change to this category takes
effect immediately (rebooting the system is not required).
ECC
ECC determines whether the system’s error correction
code (ECC) capability is turned ON (the default) or OFF .
Your system supports ECC only if all the installed
DIMMs are ECC DIMMs. If any of the installed DIMMs
are not ECC DIMMs, this category does not appear.
System Data Categories
The following categories, which are not selectable, dis-
play information about the system:
•
MICROPROCESSOR displays the type of micro-
processor installed in the computer.
•
EXTERNAL CACHE displays the size of the onboard
cache ( 256 KB or 512 KB ).
•
VIDEO MEMORY displays the amount of video mem-
ory detected in your system.
•
SYSTEM MEMORY indicates the entire amount of
installed memory detected in your system, except for
memory on Expanded Memory Specification (EMS)
expansion cards. After adding memory, check this
category to confirm that the new memory is installed
correctly and is recognized by the system.
•
SERVICE TAG displays the system’s five-character
service tag number, which was programmed into
NVRAM by Dell during the manufacturing process.
Refer to this number during technical assistance or
service calls. The service tag number is also
accessed by certain Dell support software, including
the diagnostics software.
•
ASSET TAG displays the customer-programmable
asset tag number for the system if an asset tag num-
ber has been assigned. You can use the Asset Tag
utility, which is included with your software support
utilities, to enter an asset tag number up to ten char-
acters long into NVRAM. For information on using
the utility, see “Using Drivers and Utilities” in your
online System User’s Guide.
U
sing the System Password
Feature
Your Dell system is shipped to you without the system
password feature enabled. If system security is a concern,
you should operate your system only with system pass-
word protection.
You can assign a system password, as described in the
next subsection, “Assigning a System Password,” when-
ever you use the System Setup program. After a system
password is assigned, only those who know the password
have full use of the system.
When the SYSTEM PASSWORD category is set to
ENABLED , the computer system prompts you for the sys-
tem password just after the system boots.
To change an existing system password, you must know
the password (see “Deleting or Changing an Existing
System Password” found later in this section). If you
assign and later forget a system password, you need to
be able to remove the computer cover to change a
jumper setting that disables the system password fea-
ture (see “Disabling a Forgotten Password” found
later in this chapter). Note that you erase the setup
password at the same time.
CAUTION: The password features provide a basic
level of security for the data on your system. How-
ever, they are not foolproof. If your data requires
more security, it is your responsibility to obtain and
use additional forms of protection, such as data
encryption programs.
