Troubleshooting Without Diagnostics
Power switch of new
external device is not
turned on. Turn off the workstation, turn on the
external device, then turn on the
workstation to integrate the device
with the workstation system.
When the system
advised you of changes
to the configuration, you
did not accept them. Reboot the workstation and follow
the instructions for accepting the
changes.
A plug and play board
may not automatically
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.
