You can manually assign one to the controller card. However, you will
lost PnP. Here is the steps:

1. Go to CMOS.
2. Most MB under Chipset or PCI config.
3. Disable PnP - Select Manual.
4. Find out what slot does 2940 is plug in.
5. Goto that slot and choose the irq that you want. Normally 11.
INT A LEVEL Trigger.
* Very Important 2940 is a LEVEL trigger *
6. Save and exit.

This will fix the IRQ for your 2940.
