5.6.1. Resolving Hardware Conflicts

Intel® Dialogic Board Locator Technology (BLT) and Hardware Configurable boards must be configured to interface to the host through interrupts, shared RAM addresses, and ports. Intel® Dialogic Configuration Manager (DCM) maintains configuration parameters that store the values of these settings.

This section describes how these configuration parameters are set in DCM, discusses how conflicts causing problems with your system may occur, and explains how to resolve these conflicts.

Automated Maintenance of System Parameters in DCM

In order for the Intel® Dialogic System Software to download to the boards in the system, the parameters specified in Table 13 must be set appropriately.

Table 13. DCM System Parameters 

Board Type	Parameters	Property Sheet
Hardware Configurable	D41DAddressD41DInterrupt	SystemSystem
BLT	BLTAddressBLTInterrupt	SystemSystem

The DCM system parameters are set during the installation process as follows:

• For BLT boards: Install BLT boards in the system before running DCM (refer to Section 2.1.6, Configuring and Installing BLT, PCI, and cPCI Boards). When you run DCM, it automatically detects the BLT boards, queries the Windows kernel for available interrupts and memory, and sets the values of BLTInterrupt and BLTAddress accordingly.
• For Hardware Configurable boards: Run DCM before installing Hardware Configurable boards. When you add configuration data for the Hardware Configurable boards, DCM queries the Windows kernel and sets the values of D41DInterrupt and D41DAddress accordingly. You can then configure the jumper and switch settings on the boards and install the boards in your system. This process is described in detail in Section 4.3, Configuring and Installing Hardware Configurable Boards.

As long as the Hardware Configurable board jumper and switch settings correspond to the values in DCM, and as long as no other device in the system is attempting to use the same interrupt, port, or address, the Intel® Dialogic System will start successfully with the installed hardware.

System Parameter Conflicts

Problems with the system parameter settings typically result in a system lockup. These problems include:

• Conflicts between DCM system parameter values and the board's jumper and switch settings (for Hardware Configurable boards)
• Conflicts between the system parameter settings and another device in the system

The accuracy of the system settings in DCM depends on the non-Intel® Dialogic devices in your system adhering to the standard Windows procedures for requesting the use of system resources. If they do not, then the system settings that DCM retrieves from the Windows kernel may be in use by another device. In this case, a conflict may occur.

To check the system for these problems, perform the following procedure:

1. If you have Hardware Configurable boards in your system:
   1. Power down the system.
   1. Remove the Hardware Configurable board(s) from the system.
   1. Restart the system.
2. If the system is not locked, access DCM by clicking the Intel Dialogic Configuration Manager (DCM) icon from the Intel Dialogic System Software folder.
3. Record the current system parameter settings as follows:
   • BLT boards: The system parameters for all BLT boards are the same, so you can double-click the model name for only one BLT board and make note of the values of the appropriate system parameters (see Table 13, DCM System Parameters).
   • Hardware Configurable boards: The memory and port parameters differ for each Hardware Configurable board in the system, so you must double-click the model name for every Hardware Configurable board and make a note of the values of the appropriate system parameters (see Table 13, DCM System Parameters).
4. For Hardware Configurable boards, verify that the board jumper and switch settings correspond to the values of the system parameters. If there is a mismatch, correct the board settings and proceed to step 7. Otherwise, proceed to the next step.
5. Determine which interrupt, port, or memory resources you recorded in step 3 are being used by another device in the system, as follows:
   5. Invoke the Windows Diagnostics from the Administrative Tools (Common) program group.
   5. Click the Resources tab.
   5. Then, by clicking the buttons at the bottom of the Resources tab, you can determine what IRQs, ports, and memory addresses are being used by other devices in the system.
6. Change the Intel® Dialogic system parameters in DCM to values that do not conflict with the other devices in the system.

   For Hardware Configurable boards, reset the boards' jumpers and switches to the new values.

   Note: If system resources are not available, your system administrator may need to allocate resources on the computer. Refer to General PC Troubleshooting Tips on the Intel® Networking & Communications Telecom Support Resources Web site (http://resource.intel.com/telecom/support/tnotes/gentnote/dl_hard/tn169.htm).

7. If Hardware Configurable boards were removed in step 1:
   7. Power down the system.
   7. Reinstall the boards.
   7. Restart the system and run DCM.
