Installing the AlphaStation Sound Card
Overview
Before you can use the AlphaStation sound card, you must perform certain steps,
including: planning, configuring the card, configuring the operating system, and plugging
the card into an expansion slot. The following sections (I-VI) detail these steps.
__________________________ NOTE ____________________________
Your current operating system affects how you perform the steps here. The
DEC OSF/1 AXP, OpenVMS AXP, or Microsoft Windows NT Workstation
operating systems each learn about the sound card in a different manner.
Operating system-specific differences in the steps are identified.

I.
Planning IRQ, DMA, and Address Assignments
The IRQ level and the DMA channel of the sound card are set under software control. The
I/O address is set with jumpers.
Ensure that your sound card is not assigned to IRQ levels, DMA channels, or I/O addresses
that are already in use by other devices. Plan to prevent this from happening. Keeping
records of your system's IRQ level, DMA channel, and I/O address assignments helps
ensure that you choose unused values. The equipment log section of your system's user
manual is designed for keeping this type of record.
You can gather the necessary information in other ways, depending on which operating
system your system is running.
