Dell XPS H233 manual When to Run the ISA Configuration Utility

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.

ISA 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.
