a good idea to reserve their IRQs.
Port
IRQ to reserve
1st serial port (COM1)
IRQ 4
2nd serial port (COM2)
IRQ 3
Parallel printer port
IRQ 7
PS/2 mouse port
IRQ 12
There are other configuration settings in your
BIOS Setup
that you should
review. In the PnP/PCI Setup section, make sure that the setting
'Using
Plug and Play OS'
(operating system) is
'Enabled'
or
'Yes'
. Also, make sure
that
resources are controlled automatically
.
IRQ conflicts can also occur when there aren't any free IRQ resources.
There are only 16 IRQ addresses in a PC and many are used by the PC
motherboard and standard devices. Yes, of course, under Windows 98 and
later versions of Windows 95, PCI cards should be able to share IRQs but
this doesn't always work (please don't ask us why this is...ask Bill's folks up
in Redmond). To free up IRQs, go to the BIOS Setup section called,
'Integrated peripherals' (or general features) and disable any peripheral or
port that you are not using. Then, make sure the corresponding IRQ is
*not* Reserved for Legacy Devices (see the PnP/PCI section of the BIOS
Setup).
To exacerbate the IRQ complexity, Windows does not display alert
messages when there is an IRQ conflict when installing a new card. And so
it's not surprising that even if there's no indication of a resource conflict by
Windows in the Device Manager (run Control Panel | System), there may
still be one.
The Windows Help File also has info about resolving
conflicts; see its 'Hardware Conflict Troubleshooter'.
To see Window's report on the status of the devices or if it's found a
conflict:
- Run the Windows Control Panel and select 'System'.
- Click on the 'Device Manager' tab.
- Click on the '+' sign next to the line, ‘Sound, video, and game
controllers’.
- The list should show the WavePRO interface. If the WavePRO line is
showing an ‘!’ (exclamation mark) then the interface and its driver are
not active and there's a problem.
Check to see if Windows has found the resource conflict by viewing the
‘Properties | Resources’ information for WavePRO . As noted above, if a
resource conflict is indicated, you may need to reconfigure any non-PCI or
non-plug and play card that's in your PC by manually changing its IRQ in
the devices properties windows or change on-board switches — see the
card's documentation.
OTHER IMPORTANT TROUBLESHOOTING TIPS
-
Try a "START-FROM-SCRATCH" re-installation
. The detailed
instructions for completely resetting and reinstalling a WavePRO
interface are in the README.WRI file on the driver diskette.
