Appendix A. Avoiding Hardware Conflicts

 Copyright IBM Corp. 1997 A-1

This appendix describes how to avoid system resource conflicts by

listing the default and optional hardware settings.

Avoiding System Resource Conflicts

When a new option such as an adapter card is installed, the

computer might not operate correctly because of conflicting settings

for IRQ (interrupt) levels, I/O addresses, DMA channels, and

memory addresses.

To avoid these resource conflicts, you must know the hardware

requirements, such as IRQ level and I/O addresses, for each option

and program as shown in their manuals.

Notes:

For resolving system resource

conflicts with PC Cards, see

Appendix B.

Then you must check the current resource allocations for the

computer, and select the available resource values by using the

BIOS Utility. See Appendix C.

To check if there is a resource conflict in Windows 95, do the

following:

1 Select My Computer, Control Panel, and then System.

2 Click on the Device Manager tab.

Check the list for devices with resource conflicts. A ! symbol

shows in front of these devices. If there are devices with

resource conflicts, double-click on the device and click on the

Resource tab.

Read the Conflicting device list for any resource conflicts. If

there is a resource conflict, re-assign the device to an available

and valid resource (see page A-2).

3 Close the System window.
