Sound Board Jumper
Settings
This chapter provides jumper setting information for
configuring the sound board. The jumpers on the sound
board allow you to define the following hardware func-
tions:
n
I/O addresses
n
interrupt request (IRQ) lines
n
direct memory access (DMA) channels
n
joystick connector
n
MIDI interface.
Situations that might require changing jumper settings
include:
n
You add a peripheral device that uses the same I/O
addresses, DMA channel, or interrupt setting as your
sound board (known as a hardware conflict).
n
You install a board with another joystick/game
connector in your system.
CAUTION: Sound board jumpers are
set correctly at the factory for your multimedia
configuration.
The board is set to work with many applications.
Only change (or check) the appropriate jumper
setting if a hardware conflict arises.
