6-2 Smartio CP-104UL User’s Manual
Windows NT
This section is specific for troubleshooting under Windows NT. For general problems and
solutions, please see the previous section, General Troubleshooting.
1. After the system reboots, the error message, “Another driver in the system, which did
not report its resources, has already claimed the interrupt used by xxx.” appears in the
Event Log.
This indicates the MOXA board was found, but the IRQ conflicts with another adapter. Check
the PCI BIOS IRQ settings first, and then select an IRQ that is available.
2. After the system reboots, the error message, “Cannot find any configured MOXA
Smartio/Industio series board!” appears in the Event Log.
Make sure the PCI board is seated firmly in the expansion slot.
3. The COM number of the Smartio CP-104UL board (Bus No=x, Dev No=x,
Port1=COMx), with device number xx, conflicts with others.
The COM numbers for different boards are in conflict. Change the COM number mappings
for the MOXA boards.
4. Windows NT system panics (blue screen).
The possible reason is an IRQ or I/O address conflict with other ISA Bus adapters, such as
LAN or SCSI boards, or with the system BIOS. Refer to the corresponding problem in the
previous section, “General Troubleshooting,” for solutions.
Windows 95/98
This section is specific for troubleshooting under Windows 95/98. For general problems and
solutions, see the section, “General Troubleshooting.”
1. The system fails to find the Smartio CP-104UL board!
C. The board(s) is (are) not properly plugged into the PCI slot.
D. The PCI slot is defective. Please try other slots until you find one that works.
E. The board itself might be defective.
2. After the system reboots, the error message “CP-104UL board(BusNo=x, DevNo=x,
Port1=COMx) interrupt number is invalid!” appears.
This indicates that the MOXA board was found, but the IRQ conflicts with another adapter.
Make sure the MOXA board’s IRQ does not conflict with another adapter’s IRQ. Check the
PCI BIOS IRQ settings and then select an available IRQ for the MOXA boards.
