Solving Hardware Installation Problems
You may need to reconfigure the computer when you add or remove hardware, such as an
additional diskette drive. If you install a plug and play device, Windows 2000 and Windows XP
automatically recognize the device and configure the computer. If you install a non–plug and
play device, you must reconfigure the computer after completing installation of the new
hardware. In Windows 2000, select the
Add New Hardware
icon in the
Control Panel
(for
Windows XP, use the
Add Hardware Wizard
) and follow the instructions that appear on the
screen.

configure when
added if the default
configuration conflicts
with other devices.
Use Windows 2000 or Windows XP
Device Manager to deselect the
automatic settings for the board and
choose a basic configuration that
does not cause a resource conflict.
You can also use Computer Setup to
reconfigure or disable devices to
resolve the resource conflict.

Wrong memory
modules were used in
the upgrade or memory
modules were installed
in the wrong location.
1. Review the documentation that
came with the system to
determine if you are using the
correct memory modules and to
verify the proper installation.
2. Observe the beeps and LED
lights on the front of the
computer. See Appendix C
“POST Error Messages” to
determine possible causes.
