IRQs on WinXP Pro

[Guest]

I am running a pro audio (Mia by Echo) sound card that requires its own IRQ to run, yet it is being shared on IRQ 9 by several other plug and play devices. When I go into device manager to attempt to change the IRQ setting, I am not enabled access to turn off the automatic settings and assign a new IRQ. I've also tried to modify this setting via the system BIOS, but I think Windows XP Professional reassigns the PCI IRQs itself. I have administrator status on the machine, so why am I not allowed access to these settings, and if possible, how to I gain access? Thanks.

Hi NoahFreak,

This article offers a general description of how interrupt request
(IRQ) sharing is managed in Windows XP. The description includes an
explanation of why many of the devices on your computer seem to use
the same IRQ and why Windows XP does not include...

Hope this helps.
