Software Settings

The sound card in your HP PC supports Plug and Play. This means that, when the card is installed or reinstalled,
Windows 95 is able to automatically configure various software settings to enable the computer to communicate with the
card:
•
The IRQ (Interrupt Request) line is the signal line a 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.
•
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 card.
The following table gives the preferred sound settings of the card. Windows 95 may change these settings when a card is
installed or reinstalled to avoid a conflict between the different accessories on your computer.
