Windows NT
This section is specific for troubleshooting under Windows NT. For general
problems and solutions, please see previous Section “General Troubleshooting”.
1. After system reboot, error message “MOXA C218Turbo Series Multiport
Board at base memory [XX000]: IRQ test failure!” appears in Event Log.
a. IRQ number assigned in driver is not identical to IRQ setting on the Moxa
board.
b. Other PCI devices occupy the assigned IRQ. Please reboot and enter BIOS.
Go to PCI/PnP configuration menu and set the IRQ as “Legacy ISA” device.
c. Other ISA devices occupy the assigned IRQ. If you’re not sure which device
cause the situation, please simply change another IRQ for Moxa board.
2. After system reboot, error message “MOXA C218Turbo Series Multiport
Board at base memory [XX000] not found!” appears in the Event Log.
a. Make sure you’re using the right version of driver. Please note that C218
plus board requires version 3.x driver while C218Turbo board requires
version 5.x driver.
b. Check if the board is properly plugged into ISA/EISA bus slot.
c. Check if the Memory Bank and IRQ settings in [control panel] [network]
[adapter] are the same as the settings on board.
d. Examine your PC hardware configuration thoroughly such as Shadow RAM,
SCSI device configuration, network interface card, VGA adaptor, and so on.
Any device, which occupies memory bank, should be prevented from
colliding with the memory bank used by MOXA intelligent boards. You may
refer to [Windows NT Diagnostics] in “System Administrative tools” for
more information.
e. Try the memory banks other than C800H, CC00H. Some mother board BIOS
may occupy these memory areas.
3. Windows NT system panic (blue screen).
The possible reason is IRQ or memory conflict with other ISA Bus adapters like
LAN and SCSI board or system BIOS. Please refer to the corresponding problem
in previous Section “General Troubleshooting” for solutions.
