To disable a forgotten password, perform the following
steps:
1.
Remove the computer cover according to the
instructions in "Removing the Computer Cover"
in Chapter 3.
CAUTION: See "Protecting Against Electro-
static Discharge" in the safety instructions at
the front of this guide.
2.
Refer to Table 3-2 and to Figure 3-5 for the set-
tings and location of the password jumper on the
system board.
3.
Move the jumper plug to the appropriate setting
to disable the passwords.
4.
Replace the computer cover (see "Replacing the
Computer Cover" in Chapter 3); reconnect your
computer to its power source, and turn it on.
Booting your system with the password jumper set to
the disabled position erases existing passwords.
NOTE: Before you assign a new user and/or setup
password, you must reset the jumper plug to the
enabled position.
5.
After the system has completed the boot routine,
turn off the system and remove the computer
cover.
6.
To reenable the password features, move the
jumper plug to the appropriate position.
7.
Replace the computer cover; reconnect the com-
puter and peripherals to their power sources, and
turn them on.
8.
Assign a new user and/or setup password on the
Security screen of the system setup program.
For information on assigning a new user and/or setup
password, see "Using the System Setup Program" in
the online System User's Guide.

SA Configuration Utility
NOTES: The ISA Configuration Utility is required only if
you are using a non-Plug-and-Play operating system
(such as Microsoft Windows NT 4.0 and earlier) and
your system includes legacy Industry-Standard Architec-
ture (ISA) expansion cards. If you are using the Microsoft
Windows 95 operating system, the functions provided by
the ISA Configuration Utility are handled by the Device
Manager, which can be accessed by double-clicking the
System icon in the Control Panel. See your Windows 95
documentation for instructions on using the Device Man-
ager to manage resources and resolve conflicts.
Because Dell ships only Plug and Play and Peripheral
Component Interconnect (PCI) expansion cards on Dell
Dimension systems that have a non-Plug-and-Play
operating system, the ISA Configuration Utility is not
provided with your system. You can download a copy of
this utility from Dell's TechConnect Bulletin Board Ser-
vice (BBS). For information on accessing the
TechConnect BBS, see the chapter titled "Getting Help"
in your Diagnostics and Troubleshooting Guide.
The ISA Configuration Utility is used to notify the sys-
tem of what expansion cards are installed and what
resources they use. With this information, the system
automatically configures Plug and Play expansion cards
and PCI expansion cards and can tell you how to config-
ure ISA expansion cards manually by setting jumpers or
switches. Plug and Play and PCI expansion cards do not
contain jumpers and switches; they are configured only
through software.
When to Run the ISA Configuration
Utility
Whenever you add or remove ISA expansion cards on a
system running the Windows NT operating system, you
must run the ISA Configuration Utility to ensure that no
two cards attempt to use the same resources (such as
interrupt request [IRQ] lines).
Run the program before adding or removing any ISA
expansion cards. The ISA Configuration Utility can iden-
tify and resolve any resource conflicts, as well as indicate
the proper jumper and switch settings for each expansion
card to avoid such conflicts. Running the program first
helps you determine how to configure the ISA expansion
card before you install it in your computer.
