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:
Table G-12
Audio Interface Settings
Item Setting
Base I/O address 220H
OPL III 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 optional and 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.
