Sound Board Settings - HP Kayak XA Online Manual

Sound Board Settings

The sound board in your HP Vectra PC supports Plug and Play. This means that
when the board is installed, or reinstalled, the operating system is able to
automatically configure various software settings to enable the computer to
communicate with the board:
•
The IRQ (Interrupt Request) line is the signal line your device uses to notify your
computer's central processor that it wants to send or receive data for processing.
•
The DMA (Direct Memory Access) channel is the signal line a device uses to
transfer data directly to the computer's memory. The audio interface allows you
to transfer data through the Low or the High DMA channel.
•
I/O addresses (or I/O address ranges) enable your computer's microprocessor to
access various peripheral devices connected to your system when sending or
receiving data. There are several such devices on your sound board.
The following table gives the preferred settings for the sound board:
Audio Interface:
MPU-401 UART MIDI Interface:
Joystick Interface:
Stereo Music Synthesizer
The operating system may change these settings when a board is installed or
reinstalled if one of the following occurs:
•
Another peripheral device uses the same I/O addresses, DMA channel, or
interrupt setting as the sound board (known as a hardware conflict).
•
Another joystick/game connector is already in use in your system.
