M-AUDIO Delta RBUS - Manual (Page 54)

installed, see the "Verifying Windows Driver Installation" section of this
manual. If a yellow exclamation point does appear over your Delta
R-BUS icon, you may have a resource conflict. There are several ways to
approach this problem.
NOTE: When resolving conflicts between PnP and non-PnP
devices, it is recommended to re-adjust the resource
settings of the non-PnP device first. Typically, Windows is
only aware of the resource settings of the installed PnP
devices and has no information available to it for adjusting
the PnP devices’ resources around those of the non-PnP
devices. The exceptions to this are when: (1) a non-PnP
device has a true Windows 98/95 driver written for it, (2) the
BIOS setup allows reserving an IRQ for a legacy device as
opposed to a PnP device, or (3) resource requirements for
the non-PnP device have been manually entered into the
Windows Device Manager. In these cases Windows is aware
of the non-PnP device’s resource requirements.
One of the quickest ways to change the resources assigned to a PCI card
like the Delta R-BUS is to merely relocate the card to another PCI slot.
With the computer’s power off, remove the Delta R-BUS from its current
PCI slot, move it to another available PCI slot, and turn your computer
back on. More often than not, this will change the IRQ assignment of the
Delta R-BUS 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 R-BUS’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 R-BUS 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.
