5.2.3 Error Messages in Windows NT
Error message from Windows NT: “At least one service or
driver failed during system startup. Use Event Viewer to
examine the event log for details.”
Possible error source: The AVM ISDN-Controller A1
driver software cannot be loaded. This may be due to an
incorrect I/O address setting (jumper setting on the
Controller) or to an incorrect interrupt (IRQ).
Solution: For detailed information about the error, open
the Windows NT Event Viewer (“Administrative Tools”
folder). Check the messages from A1BASE and the
Service Control Manager.
The “Administrative Tools” folder also includes the
“Windows NT Diagnostics” program, with which you can
check the resources in your system. Find out which I/O
addresses and interrupts (IRQs) are available.
If the jumper position on the Controller must be changed
to another I/O address, exit Windows and turn off the
computer. Change the jumper position, restart Windows
NT, and then start the A1 Setup program from the “AVM”
group to enter the new I/O address and any change to the
interrupt (IRQ).
As a final step, Windows must be restarted to implement
these changes.
Error message: “Resource conflict detected...“
Possible error source: The ISDN-Controller cannot use
the configured I/O address or interrupt (IRQ), as it is
already assigned to another device.
Solution: Change the IRQ or the I/O address. Use the
“Windows NT Diagnostics” program from the “Admini-
strative Tools” folder to find out which I/O addresses and
interrupts are available. Turn off your computer, change
the jumper position and then restart Windows. Use the
A1 Setup program to make the corresponding changes
to the software. See sections 4.1 and 3.2.2 for more
information.
