Incompatibilities
Windows XP, Windows Me, and Windows 2000 IRQ conflicts occur if a
device either is not detected during the operating system setup or is
detected but incorrectly configured.
Windows XP
To check for conflicts on a computer running Windows XP, perform the
following steps:
1 Click the Start button, and then click Control Panel.
2 Click Performance and Maintenance, and then click System.
3 Click the Hardware tab, and then click the Device Manager button.
4 In the Device Manager list, check for conflicts with the other devices.
Conflicts are indicated by a yellow exclamation point (!) beside the
conflicting device or a red X if the device has been disabled.
5 Double-click any conflicting device listed to bring up the Properties
window so you can determine what needs to be reconfigured or
removed from the Device Manager.
Resolve these conflicts before checking specific devices.
6 Double-click the malfunctioning device type in the Device Manager
list.
7 Double-click the icon for the specific device in the expanded list.
The Properties window appears.

window reports what expansion cards or devices are sharing the
device's IRQ.
