IRQ Conflicts with PCI Display Adapters (129955)
The information in this article applies to:
This article was previously published under Q129955 SYMPTOMS
When you install a Peripheral Component Interconnect (PCI) video adapter
that is configured to use a particular interrupt (IRQ), Windows 95 may
configure it to use another IRQ that is already in use by another device.
CAUSE
PCI devices can share PCI IRQs, but Windows 95 does not support sharing
PCI IRQs with other non-PCI devices (such as an IDE controller).
Windows 95 display drivers do not use an IRQ. However, PCI adapters
request an IRQ for full backward compatibility.
RESOLUTION
Use Device Manager to resolve the conflict by assigning a different IRQ
to one of the conflicting devices.
