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:
Base I/O address220H
OPL III I/O address388-38Bh
Interrupt IRQ 5
8-bit DMA Channel 1 and Channel 0 or 3
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 then reinstalling
each card, one at a time, until the card that is causing the conflict is found.
