Troubleshooting Software and Hardware
Problems in the Windows Vista™ Operating
System
If a device is either not detected during the operating system setup or is
detected but incorrectly configured, use Windows Vista Help and Support to
resolve the incompatibility. Windows Vista™ is a new operating system, so
many older devices may not have drivers or applications for Windows Vista.
Check with your hardware manufacturer for further information on their
device.
