Important Run ConfigSafe (or a similar application) to take a "snapshot" of your Windows NT Workstation configuration before installing an optional device. Using this snapshot, you can view and compare the changes in the Windows NT Workstation configuration after you install an option. Also, if you have problems configuring the option after it is installed, ConfigSafe allows you to restore the Windows NT Workstation configuration to the previous settings. Note: If you have preinstalled software, ConfigSafe took a snapshot of the initial Windows NT Workstation configuration when you started your computer for the first time. You might be able to use this snapshot to restore the Windows NT Workstation configuration to the initial settings. ConfigSafe is a part of the preinstalled software in your computer. It is also available on the Software Selections CD. For more information, see "Using the ConfigSafe program" on page 111 and "Software" on page 4. Removing the cover and front bezel You must remove the computer cover to access the internal components, such as the system board and drive bays. When disconnecting cables, be sure to note where they attach, so you can correctly reattach them later. Before you begin 1. Shut down your operating system, remove any media (diskettes, CDs, or tapes) from the drives, and turn off all attached devices and the computer. 2. Unplug all power cords from electrical outlets. 3. Disconnect all cables attached to the computer. This includes power cords, input/output (I/O) cables, and any other cables connected to the computer. Note: For more information on connectors, see "Connecting computer cables" on page 13. Attention: If you have set an administrator password, before removing the computer cover, read the important information in "Using an administrator password" on page 47. Chapter 5.
