Understanding the Software-Configurable Settings 

Your audio card supports the Plug and Play (PnP) 1.0a standard. This allows a PnP system to assign 

the necessary resources such as I/O addresses, interrupt lines and DMA channels to your card when 

you install it. 

If you are using Windows 95, its PnP configuration manager will automatically set up your card’s 

resources. If you are using a non-PnP system such as Windows 3.1x, you must run your PnP 

configuration manager to configure the card. For details, refer to the documentation of your PnP 

configuration manager. 

This section explains the following software-configurable resources of your audio card: 

 

Input/Output (I/O) Addresses 

 

Interrupt Request (IRQ) Lines 

 

Direct Memory Access (DMA) Channels 

 

Input/Output (I/O) Addresses 

I/O addresses are communication areas used by your computer’s central processor to distinguish 

among various peripheral devices connected to your system when sending or receiving data. 

Table 1 lists the default I/O address ranges assigned by the PnP system to various devices on your 

audio card. 

I/O Address Range 

Device 

200H to 207H 

Game/Joystick port 

220H to 22FH 

Audio interface 

330H to 331H 

MPU-401 UART MIDI 

388H to 38BH 

Stereo music synthesizer 

620H to 623H, 

A20H to A23H, 

E20H to E23H 

Advanced WavEffects synthesizer 

100H 

3D Stereo Enhancement device
