Problem Installing an Add-On Sound Card
You can install a new add-on sound card if you do not wish to use the
integrated sound features of your PC.
NOTE Plug and Play operating systems such as Windows 95, Windows 98 and
Windows 2000 should, in normal circumstances, be able to allocate the IRQs
that are used according to the hardware installed in the PC.
However, in certain circumstances it may be necessary to set the
PnP
Operating System
field to
NO
so that the board is recognized in Windows
95. This is especially true when there are many accessory boards (three or
more) installed in your PC.
Problem To try and fix this...
You have installed a new add-on sound
board and you have not disabled the
integrated audio features of your PC. Disable the integrated audio:
Turn on or restart the PC.
1 When the Vectra logo appears, press
F2
to enter the Setup
program.
2 Go to the Advanced menu.
3 Select Integrated Audio Interface and press Enter .
4 Set Integrated Audio Interface to Disabled .
5 Exit Setup and save the changes.
You have installed a new add-on sound card
and you get a message telling you that
there is no IRQ (Interrupt Request) available
for the sound card.
•
Check that you have followed the installation instructions
provided with the sound card.
•
Check that you have disabled the integrated audio (see above).
If there is still an IRQ problem...
... and your PC is running Windows NT and
has an ISA card installed 1 Restart the PC and press
F2
when the Vectra logo appears.
2 Reserve an IRQ for the ISA sound card. To do this, go to the
ISA Resource Exclusion submenu of the Advanced menu
and then set the chosen IRQ to Reserved . Also, set the PnP
Operating System item to NO .
3 Exit Setup and save the changes.
4 Redo the Windows NT installation procedure for the sound
card.
