M-Audio Delta 1010 Manual page 43

"Verifying Windows Driver Installation" section of this manual. It might take
more than one PCI slot relocation to find an open IRQ.
If relocating your card to another PCI slot does not cure the Delta 1010's
conflict(s), then you must do some further investigation to determine the exact
nature of the conflict(s). Again, go to the Windows Device Manager, highlight
the Delta 1010 or other devices with conflicts and click the "Properties" button
at the bottom of the Device Manager window. This will open the properties page
for that device. Select the "Resources tab" in order to view the resource
assignments, plus possible conflicts. You may learn more about a conflict by
highlighting each item one-by-one (done by clicking on them, or scrolling
through the list using your keyboard cursor keys) and examining the "Conflicting
resource list:" at the bottom of the box.
Sometimes it is possible that a resource problem is not showing up in the
conflicting resource list or as a yellow exclamation point in the Device Manager.
If you have any doubt about the configuration of your device (or just want to
double-check), you can view all of the devices and their assigned resources by
highlighting "Computer" at the top of the Device Manager list and clicking the
Properties button. This will allow you to view a list of assigned IRQ numbers on
the left, and the associated devices on the right. If a number does not show up
in this list, it means that it is available for use. Look also for IRQs that are shared
by more than one device. While the Delta 1010 may share an IRQ with some
devices, not all devices are capable of sharing IRQs. An entry that reads "IRQ
Holder for PCI Steering" along with an installed PCI device (such as the Delta
1010) is normal. If you see another device showing up on the same IRQ as the
Delta 1010 (such as a video card, SCSI adapter, or USB Host Controller), then it
is possible that this is the source of the conflict. Typically, if you move one of
the conflicting cards to another PCI slot, an IRQ conflict will disappear.
Address conflicts are rare amongst PCI devices, but if there is no obvious IRQ
conflict, why not check for I/O Address conflicts while in the Device Manager?
