another available PCI slot, and turn your computer back on. More often than
not, this will change the IRQ assignment of the Delta 44 when you re-enter
Windows. After returning to Windows, follow the steps outlined in the
“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 44’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 Delta44 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 Delta44 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 44) is normal. If you see another device
showing up on the same IRQ as the Delta 44 (such as a video card, SCSI adapter, or
USB Host Controller), then it is possible that this is the source of the conflict.
