I have several devices all using IRQ 22 (I've got several open spaces in the prime 1-16 area) and it makes the system slow, unstable, and unable to play sound properly. Now, my motherboard is PCIPnP compatible (very new intel chipset Mobo) and Windows XP Professional (SP2 fully updated) should certainlly allow me to change IRQ numbers from within the OS. Changing the slot the cards are in does NOTHING. Any card that's moved just gets the exact same number. The two devices that are conflicting are my harddrive controller and my soundcard which is the cheapest card creative is selling right now... about 25 USD... creative 24 bit whatever the heck... Anyway, I can see the area in the device manager where I'm supposed to be able to change IRQ settings but they're ghosted out. I've actually never seen this field be anything but ghosted out on any machine. Why is this? I see on the MS website and all over the net people just saying "go to the device manager and change the IRQ"... And because the card gets assigned the SAME IRQ no matter what slot I put it in, it's clearly not beyond the power of the hardware/software to handle different IRQs for different slots in the Mobo. Is this setting locked? Is there an app I can get that will just do the deed? Can I modify my registry to unlock this? What's going on here? I have even tried different sound cards and I get the same problem every time. The Creative card doesn't make the computer AS slow as other cards but the problem is still very noticable.
