Alternately, if your system BIOS supports it, you can reserve the offend-
ing legacy card’s IRQ from within the system BIOS. As your computer
boots, you should enter your motherboard’s system BIOS configuration
routine by pressing some magic key. This keystroke differs from one
motherboard manufacturer to another but usually involves pressing the
F10 function key or the Del key (consult your motherboard owner’s
manual if in doubt). Often the BIOS will actually prompt you and tell
you what keystroke to make while booting up. Once you’ve found your
way into the BIOS setup, look for an IRQ assignment page. Often you
can assign specific IRQ’s to ISA legacy cards. When you do, the PnP
BIOS then knows not to assign that reserved IRQ to a PnP interface card.
Although reserving the legacy IRQ is best done in the system BIOS, the
last resort is to reserve it in Windows 95. First press the Windows Start
button, then select

. This should open

tab. Select the
Interrupt Request (IRQ)
radiobutton in order to display the list of reserved IRQ’s. You may then
add to the list any IRQ’s you would like to reserve for your legacy ISA
card(s).
Troubleshooting
This section addresses potential problems that are not usually due to
resource conflicts within the computer.
Hardware Troubleshooting
Below are examples of common hardware troubleshooting situations:
Problem:
No sound is coming from the DMAN 2044 during playback.
Possible Cause 1:
Improper connections to the audio outputs of the
DMAN 2044 card. Verify that the DMAN 2044 OUT(s) are properly con-
nected to an external mixer/amplifier/speakers.
Possible Cause 2:
Volume control misadjusted in the Windows
audio playback mixer. There is a playback volume slider for each
DMAN 2044 output -- make sure the volumes are neither set too low nor
muted.
Possible Cause 3:
The audio application is not properly configured
to use the DMAN 2044 as its output card, or the application is outputting
audio on a different output pair than you expected.
Possible Cause 4:
There is a resource conflict with one or more other
