Resolving a Resource Conflict

The most common resource conflict resolution scenarios for Windows 2000/XP/2003 and the Diva Client cards are covered on this page.

Another useful tool to help resolve a resource conflict is the DtectPCI Utility. You will find information on how to use this tool in our Troubleshooting section under Using the DtectPCI Utility.

Before commencing these diagnostic procedures, please ensure the latest version of the Diva Client software is installed.

Check the Plug and Play settings in the BIOS.

• If the BIOS has a setting Plug and Play Operating System (i.e. the Operating System is responsible for allocating resources), then this should be enabled or yes for Windows 2000/XP.



• If the BIOS has a Plug and Play BIOS setting (i.e. resource allocation to be performed by the BIOS), then this should be disabled or no for Windows 2000/XP.

Background:

Plug and Play functions can be performed either by the BIOS or by the operating system. Windows 2000/XP is a plug and play operating system, so resource allocation should not be done by the BIOS.

Note: Be careful to ensure exactly which setting you are configuring, as the descriptions for both settings are very similar, although their function is exactly the opposite of each other. If you cannot find this setting in your BIOS setup, check if you have the option to select the installed operating system. In some BIOS versions this has the same effect.

Note: If the most common resolutions offered do not resolve the issue, the system may need a BIOS upgrade to enable the correct function of the automatic resource allocation. Contact the PC supplier to see if a BIOS upgrade is available from the manufacturer.

Using Windows Device Manager

• Check if the Diva card is present in the Device Manager under Network Adapters.



• Check if the entry is marked as having an error with the (!) symbol.



• Click on the Diva card entry to see if another device is marked as being "in conflict".



• Go through the available resources to determine if free resources exist.



• Use Device Manager to allocate free resources to the Diva card or the device which is conflicting with it. Note that for a device conflicting with the DIVA card, you may need to use its Install software to change the resources allocated to it.

Check the hardware

• Uninstall the Diva card following the uninstall procedure. Power down your computer, move the Diva card to a different PCI / PCMCIA slot and restart Windows.
  The Diva Installation routine will be initiated, and Windows may allocate new resources to the card.



• If the problem persists, move other PCI or PCMCIA cards to isolate the problem card.



• Does another type of card (e.g. ISA) or device clash with the DIVA card?



• Can this device be allocated other resources or disabled via hardware switches, BIOS setting, or setup software?



• Is an updated driver available for this device?



• Can the device be physically removed?

If none of the above helps to solve the problem, it is worth trying to install the Diva card in another PC. This will rule out a hardware defect of the Diva card.
