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.

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.
