IRQ's in Windows 2000 Pro

By ajcanal ·
I've noticed that W2K Pro has assigned IRQ 9 to at least 8 devices in my system. These include the Sound Card, NIC, Modems, SCSI card and others. There is no way for me to manually change the IRQ's since they are grayed out and uninstalling and re-instaling the devices dosen't seem to work.

The Device Manager does not show any conflicts but when I view the devices by type is when I notice IRQ 9 being used. As I recall, IRQ 9 is IRQ 2 redirected so I'm surprised to see this. There are other IRQ's available but not being used.

Is there any reason for this in W2K Pro? Is this normal?

This is just the OS using IRQ sharing which is very legal (if supported by the hardware). As long as all devices are working okay, everything is fine.
I have commonly seen this on laptops running Win2K.

Normal and legal. I would venture that every device you see using the same IRQ is a PCI device or attached to the PCI bus. One of the advantages of the PCI bus was the ability to share IRQ's
