Verifying that Intel Dialogic is using a free IRQ and base memory
address
The Intel Dialogic driver installation automatically assigns an IRQ and base memory address for
the boards, but in some cases its choices may conflict with an existing IRQ or base memory
address assignment.
1. In DCM, click Configured Devices in the main dialog box and then choose Action >
Configure Device .
2. Click the System tab.
3. The BLTInterrupt parameter contains the IRQ assigned to Intel Dialogic. To verify
that this is a free IRQ, click Start > Programs > Accessories > System Tools >
System Information . In the System Information dialog box, double-click Hardware
Resources , and then double-click IRQs .
Do one of the following:
Q If the IRQ assigned to Intel Dialogic is not listed, you do not need to change it. Go
to the next step.
Q If the IRQ assigned to Intel Dialogic is listed, make a note of one that is not. Close
the screen. In DCM change the
Value of the BLTInterrupt parameter to a free IRQ.
Click OK .
Important: Windows assigns IRQs to PCI boards at startup, so they cannot be
changed in DCM. Any IRQ change you make here will not be applied to PCI boards. If
you have PCI boards, you need to work around existing IRQ assignments.
