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 integrated
cache (
256 KB
).
•
VIDEO MEMORY
displays the amount of video mem-
ory detected in your system (
1 MB
or
2 MB
).
•
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.
Reference 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 number
has been assigned. You can use the Asset Tag utility to
enter an asset tag number up to ten characters long
into NVRAM. For information on this 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 system pass-
word 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
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.
