You need to change the IRQ on the card to something nice and safe, like 10 or 11. > Does the value of the irq matter? I hear lower irq's have higher priority. > Is a higer priority necessary for a modern ethernet board? Some devices can share IRQs, though it's not recommended. So the value does matter in a very big way. The priority is not an issue here. Simply change the network card off of IRQ 14 and it'll probally work. You should have a driver/setup disk that came with the card, BTW which will allow you to change/make sure the IRQ is 10. > Are there problems with shared irq's on PCI boards?

In that case you might want to take a quick tour through your BIOS, change the PNP OS Installed Option to yes, and PNP Something or another assign to manual. That might fix some of your problems too.
