Resolving Hardware Configuration Conflicts

Resolving Hardware Configuration Conflicts

Use the following information to help resolve hardware configuration conflicts:
  1.  Run the Setup program to view and change resources used by the  system board functions and the PCI interrupt requests (IRQs), if  necessary. Record the current settings before making  any changes. (See 'Configuration/Setup Utility Program')
  2.  Determine which adapter or device is causing the error. The EISA  Configuration program specifies how the server checks for resource  conflicts. Initially, this verification mode is set to automatic.  Use the Advanced selection of the EISA Configuration  Diskette's View or edit details screen to  change the setting (see 'Configuration/Setup Utility Program').

     The automatic verification mode might disable adapters  or system board features. For example, if you choose IRQ 4 for  an adapter, the program disables Serial Port 1, which uses IRQ 4.  If this happens, and you do not want this feature disabled, choose  another IRQ for the adapter.

     If you set the verification mode to manual ,  the configuration utility program does not   try to resolve a conflict. Instead, you have to  determine if a resource conflict has occurred and then resolve the  conflict. When the verification mode is set to manual,  an asterisk (*)  appears on the View or edit details screen  next to adapters in conflict.

     If the EISA Configuration program cannot resolve a configuration error,  it deactivates  the adapter and displays the deactivated status  (<>) on the View or edit details screen. Use the Advanced  selection of the EISA Configuration Diskette's View or edit details  screen to update or copy the server's system configuration information  file (see 'Configuration/Setup Utility Program').

  3.  Change configuration resource allocations. Use the built-in Setup  program to view or change system board resource allocations. Use the Advanced selection of the EISA Configuration Diskette's  View or edit details screen to view the available or the used system  resources (see 'Configuration/Setup Utility Program'). Use the Edit Changes  selection to change resource allocations for complex configurations.
  4.  Change adapter jumpers or switches. Jumpers and switches define the  system resources that a device can use. If the settings are incorrect or  set to use a resource that cannot be shared, a conflict occurs and the  device remains deactivated by the configuration program.  Use the EISA Configuration Diskette's  Step 4, Examine switches or print report  screen to verify switches  (see 'EISA Configuration Menu Selections'). Read the documentation supplied with the  device.
  5.  Change system board jumpers or switches. Remove the cover then,  refer to the system-board diagram inside the server.
  6.  Remove the device or adapter. Some configurations are not  supported (for example, you cannot operate the server with two  PCI SVGA adapters installed).
  7.  Assign EISA memory addresses starting with DFFFF (in hexadecimal),  and work downward to address C8000 (in hexadecimal). PCI devices  are automatically assigned memory addresses starting from C8000 working  upwards.
