Can My DAQ Boards Share the Same IRQ Level?

Hardware: Multifunction DAQ (MIO)

Problem:
After installing my PCI-6527, PCI-6034E, PCI-6035E and PCI-6711 boards, I noticed that a few of these boards have the same IRQ level assigned to them. Is that okay?

Solution:
Yes, it is fine if the PCI boards are using the same IRQ levels. You only need to worry if the boards use the ISA bus, since ISA devices require unique IRQs. The PCI bus was designed such that PCI devices can share IRQ levels.
