M-AUDIO Delta DiO 2496 - Manual (Page 21)

If the Delta DiO has requested an IRQ in use by another PCI device, but there are
other IRQs available, moving the Delta DiO card to an alternate PCI slot may help.
Changing PCI slots will cause the PnP system to recognize the card as new hardware
and re-establish it with a different IRQ. Some newer BIOS (see your computer man-
ual) allow the selection of an IRQ for each PCI slot on the motherboard. This can
be very handy in resolving IRQ assignments for PCI devices. However, if there are
no IRQs available, some kind of reconfiguring or reprioritizing your system is in
order. Optionally, a second hardware configuration can be created for running two
sets of hardware profiles. See your Windows documentation for help in this area.
NOTE: When resolving conflicts between PnP and non-PnP
devices, it is usually easier to re-adjust the resource settings of
the non-PnP device. Windows is only aware of the resource set-
tings of the installed PnP devices and has no information avail-
able to it for adjusting the PnP devices around the non-PnP
devices. The exception to this is when a non-PnP device has a
true Windows 95/98 driver written for it, or if the BIOS allows
instructions for an IRQ to receive a legacy device as opposed to
a PnP device. In that case Windows is aware of the non-PnP
device’s resource requirements.
IMPORTANT: Most sound card installation problems result from
attempting to use system resources (IRQs, address locations)
already in use by other hardware or software in the system.
