What is the difference

[BTRY B 529th FA BN]

What's the difference between these two IRQ entries:

Intel(R) ICH10 Family PCI Express Root Port 1

&

Intel(R) 7500/5520/5500/X58 I/O Hub PCI Express Root Port 1


EDIT: and how do they pertain to the PCI Express slots???

Think what a hub looks like and think of the slots as ports in the back of the hub. IRQ=interrupt request. IRQ lets every part communicate in turn.

The more PCI-E slots the more IRQ gets dedicated to the hub so that it can communicate in turn with each port/slot. Multitasking makes it appear as if it all communicates at the same time but that is false and the board needs timing just like an engine in a car.
