Introduction

Audio Configuration allows you to update the Audio settings in your DOS and Windows system files SYSTEM.INI, CONFIG.SYS and AUTOEXEC.BAT.  Your old system files will be saved with the extension B~K.

Audio Configuration will prompt you to reboot your system for the system configuration changes to take effect.

CAUTION: Some settings that you selected may require you to change the jumpers on the audio card accordingly.  Please refer to the Getting Started manual for the exact location of these jumpers.  If the settings do not match the jumper position, the Audio device drivers will report errors when your system or Windows is restarted.


Base I/O Address

The I/O (input/output) address is the address used by your computer's microprocessor to distinguish the audio interface from other peripheral devices in your system when sending or receiving data.  Twenty consecutive I/O addresses are occupied by the audio interface.

You can select your desired base I/O address setting from the available base I/O addresses listed in the list box.


MPU-401 MIDI Port

MPU-401 MIDI Port is used for MPU-401 UART mode interface.  You can select your desired settings from the available base MIDI ports listed in the list box.


IRQ

The IRQ (Interrupt) line is the signal line your audio interface uses to notify your computer's central processor that it wants to send or receive data for processing.  You can select your desired setting from the available IRQ lines in the list box.


DMA Channel

The DMA (Direct Memory Access) channel is the signal line your audio interface uses for data transfer directly to the system's memory.  The audio interface allows you to transfer your data through an 8-bit or 16-bit DMA channel.  Select your desired setting from the available DMA channels in the list box.

Please note when you select the option DMA under the 16 bit (High) DMA channel list box, you are transferring 16 bit digitized data through the 8 bit DMA channel (which you have selected from the low DMA list box).
