A-12 Further Troubleshooting

Resolving Audio Hardware Conflicts

Hardware conflicts occur when two or more peripheral devices contend for the same signal lines

or channels. Conflicts between the audio interface and another peripheral device may be due to the

settings of the base I/O addresses, interrupts, or DMA channels. The audio interface typically has

the following settings:

Item Setting

Base I/O address 220H

FM Synthesizer I/O address 388-38Bh

Interrupt IRQ 5

8-bit DMA Channel 1

To resolve hardware conflicts:

1. Change the hardware settings of your audio card or the peripheral card in your system if the

peripheral card is using the audio interface setting. You can change settings for integrated audio

using Computer Setup.

2. If you are unsure of the settings of the peripheral cards, you can isolate the source of the

problem by temporarily removing all cards and other essential cards such as the disk controller.

After that, add the cards back one at a time until the card that is causing the conflict is found.

the computer to increase the volume.

Troubleshooting Using Compaq Intelligent Manageability Features

The Local Alert Pop-Up Dialog notifies you of an impending or actual hardware failure. If the

computer is connected to a network and the Compaq Insight Management Agents are installed and

configured, an Simple Network Management Protocol (SNMP) trap (message) is sent to the

specified SNMP-compliant management application.

The Local Alert Pop-Up Dialog also tells you the steps you need to take prior to a hardware

failure to avoid loss of data and damage to the computer. The system administrator can create a

customized action message that might include contact telephone or pager numbers.

To close the Local Alert Pop-Up Dialog, click the Close button. To retrieve fault information after

closing the dialog, run Compaq Insight Personal Edition.

For more detailed information, refer to the online Intelligent Manageability Guide.
