NI-FBUS Process Startup: Fatal Error

[RAIOH]

I installed PCI-FBUS card, NI-FBUS COMM SW for Windows v 3.2.1 (CM and Configurator) on my Windows XP, activated the licenses and enabled the PCI-FBUS board through Configuration Utility.  When I started NI-FBUS Communication Manager, I got the following error: 

"NI-FBUS Process Startup: Fatal Error

Initialize request to Board 0 timed out, NI-FBUS may not be receiving interrupts from board.  Check your board IRQ settings with the NI-FBUS interface configuration utility.  NI-FBUS will not Exit." 

All the settings in the Configuration Utility were set to default.  The NI-FBUS Communication Manager will only run successful if H1 interface board properties is set to "Polled Mode."  How do I fix this issue?

Hi, I asked the guy who developed NI-FBUS 3.2. They told me this is a history problem, when Windows OS is upgraded to XP or above, the IRQ mode is not suggested to use any more. So from the NI-FBUS 4.0, they removed IRQ mode supporting. It is strongly recommended using poll mode in NI-FBUS software.
