Understanding the System Resource Settings: Sound Blaster Live! Value Sound Card User's Guide

Overview • Input/Output (I/O) Addresses • Interrupt Request (IRQ) Line • Direct Memory Access (DMA) Channel

Overview

This section explains the following software SB emulation resources—not hardware resources— of your card.

NOTE: If your card encounters a conflict with a peripheral device, you may need to change its resource settings. For details, see "Resolving I/O Conflicts" in the section "Troubleshooting". When any resource setting is changed, make sure that the environment variables (see "Understanding the Environment Variables" in the section "Using the Sound Card) reflect the changes as well. You can view your system environment by typing SET at the DOS prompt.

Input/Output (I/O) Addresses

NOTE: In the following tables the preferred values are in bold.

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. Possible default input/output (I/O) addresses.

Interrupt Request (IRQ) Line

An IRQ line is a signal line that a device uses to notify your computer’s central processor that it wants to send or receive data for processing.

Table 2. Possible default interrupt request (IRQ) line assignment.

Direct Memory Access (DMA) Channel

A DMA channel is a data channel that a device uses to transfer data directly to and from the system memory.

Table 3. Possible default direct memory access (DMA) channel assignment.
