18 Installing and troubleshooting
A resource conflict occurs when a problem exists with internal connections.
Resource conflicts can include either Input/Output (I/O) or Interrupt Request Lines
(IRQ) conflicts.
An I/O base (Input/Output) conflict occurs when a request is made for a certain
resource, and a resource problem prevents that request from being granted.
Interrupt Request Lines (IRQs) are hardware lines over which devices can send
interrupt signals to the microprocessor. When you add a new device to a computer,
you sometimes need to set its IRQ number by setting a DIP switch. This specifies
which interrupt line the device can use. An IRQ conflict occurs when multiple
requests are made for the same resource. Check for resource (I/O base and IRQ)
conflicts in the Device Manager.
Windows 95, Windows 98, and Windows Me:
1 On the Start menu, point to Settings, and click Control Panel.
2 Double-click the System icon.
3 Click the Device Manager tab.
4 Double-click Scanners (Windows 95) or Imaging Device (Windows 98 and
Me).
5 Look for an exclamation point in front of the scanner name. The exclamation
point indicates a resource conflict.
Note: For some computers, the sound card might be trying to share an IRQ with
the LPT port. If that is the case, select the Sound Card in the Device
Manager, and then click Properties to change its resource settings so
that the sound card uses a separate IRQ. For more information regarding
these settings, see the documentation provided with your computer.
