M-AUDIO Delta RBUS - Manual (Page 55)

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 R-BUS 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 R-BUS) is normal. If you see another device showing up on the
same IRQ as the Delta R-BUS (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? You may view the list of assigned I/O addresses by selecting
the "Input/output (I/O)" radio button below the "Interrupt Request
(IRQ)" radio button at the top of the Device Manager page. I/O
addresses are displayed as 16-bit hexadecimal numbers, therefore one
might note that an address of 300h (the default address of the Winman
4X4/s, for instance), will read "0300" in this list.
If scanning all the resource lists in the Device Manager does not provide
an answer or clue to the resource conflict, you might want to exit
Windows and do a final inspection of your computer’s BIOS setup. Some
newer BIOS’s (see your computer manual) allow the reservation of an
