Resolving Hardware Conflicts

This chapter describes the possible hardware conflicts be-
tween your sound card and other interface cards if your sys-
tem does not support the Plug and Play (PnP) 1.0a
specification, and ways of resolving these conflicts. PnP sys-
tems will not have hardware conflicts because the system as-
signs the appropriate configuration from available resources.
Hardware conflicts occur when two or more devices use the
same I/O address, IRQ, or DMA channel. The default setting of
the <Product> Sound Controller Audio Card is as follows:
This setting might come into conflict with other devices such
as a network card, video card, scanner, printer or SCSI
adapter/controller card.
To resolve hardware conflicts:
1. Find out the current board setting (DMA channel, IRQ, I/O
port address) of the sound card by running SNDINIT.EXE.
2. If you know of any peripheral card in your system that is
using the same setting, change the hardware setting for
the other card or the sound card.
3. If you are unsure of the settings of the peripheral card,
remove all cards except the sound card and other essen-
tial cards from your system. Run SNDINIT.EXE each time
you remove an interface card. If your sound card functions
properly after removing an interface card from your sys-
tem, the interface card you just removed is in conflict with
your sound card. Find out the DMA channel, Interrupt re-
quest line, I/O port address which the interface card is
using. Change the settings on your sound card or the in-
terface card so that the two are not using the same val-
ues.
Note It is advisable to change the jumper settings on the
