The IRQ (Interrupt Request) resource is best changed from the motherboard 
BIOS setup screen. 

PCI cards are configured differently than ISA cards: unlike ISA cards, it 
is usually not possible to change the IRQ for a PCI card from the operating 
system. 

To change the IRQ, it is necessary to assign or change the IRQ for the PCI 
slot the card is plugged into.  This is done in the motherboard's BIOS 
setup program. 

To enter the BIOS setup:
  * Turn the computer on and watch the screen for a message like
      "Press [_] to enter setup".  
    The "[_]" will be some key such as [DEL] or [F1].  
  * Press that key and the setup program will appear.  

A menu with various categories will be displayed.  For PCI cards, the options
we want to change will be in a section called PCI/PNP Configuration or
similar.  

Your BIOS setup may have an option to assign PCI slots to "Auto" or to 
"Manually" set an IRQ.  For example, if your Daytona is plugged into slot 1, 
your PCI video card is in slot 3, and both cards are using IRQ 11, you should
change the setting for slot 1 to another available interrupt.  

If your BIOS does not offer such a setting, a BIOS upgrade from your 
motherboard manufacturer should allow you to manually assign the IRQ 
resources for the PCI slots.
