Appendix D
Sound Board Configuration
This appendix provides the configuration settings for the sound board. The factory default settings
for the sound board are as follows:
MIDI Interface
Base I/O Address: 330H
Audio Interface
Base I/O Address: 220H
Joystick Connector: Enabled
Interrupt: IRQ 7
Low DMA channel: 1
High DMA channel: 5
The factory default settings of the sound board or another peripheral device on the system may
need to be changed if any of the following occurs:
n
A peripheral device uses the same I/O addresses, DMA channel, or interrupt setting as
your sound board (known as a hardware conflict).
n
Another Joystick/Game Connector is installed in the system.
Changing Hardware Settings
Jumper configurations define the hardware settings of the sound board. Before actually changing a
jumper configuration, identify the current and the proposed new setting. Jumper locations for the
board are shown in Figure Appendix D-1.
CAUTION: As many applications are designed to
work with the sound board’s default settings, do not
change the settings unless it is absolutely necessary
(hardware conflicts may result).
