you can make these changes in your bios settings,... but if your not familiar with messing with irqs and such, you can cause quite a mess with the whole irq config,... if you have open pci slots, i suggest you just change the position of your network card... = ), and the auto-irq will reassign different irq's... if this doesn't work, consult your motherboards manual, some manufacturers supply info on the actual irq's shared by specific pci slots... hope this helps!
