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 95/98 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 66 is to merely relocate the card to another PCI slot. With the computer’s power off, remove the Delta 66 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 66 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 66’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 66 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.
