One more weird computer thingy...
I think I'm still having problems with my soundcard because it, my video card and my USB 2.0 pci card are all apparently using IRQ 11. It's my understanding that soundblaster cards don't play well with others... and besides, it doesn't seem right that they should have to share.

I've tried both having my bios auto-control settings, and letting my OS do it. In both instances, ALL my PCI is on IRQ 11.

My questions are these (answer me these questions... four?):
1. I know I can reserve an IRQ for a device in the bios. How do I assign devices to these reserved IRQs?
2. Should I assign these devices (USB 2.0 card, Soundblaster Audigy 2 ZS, Winfast Ultra 250) to any particular IRQ?
3. Is this actually the best thing to do?
4. Do you have any other advice?

Thanks :)

Re: #1

"Manually assigning IRQs to PCI slots in the system BIOS as a troubleshooting method may work on some non-ACPI systems that use a standard PC hardware abstraction layer (HAL), but these settings are ignored by Plug and Play in Windows if ACPI support is enabled. If you must manually assign IRQ addresses through the BIOS to a device on an ACPI motherboard, you must reinstall Windows to force the installation to use a Standard PC HAL."

Go to Device Manager (Control Panel/System/Hardware), click on 'Computer', then double click on 'ACPI-PC'. Go on with 'Driver' and 'Update Driver'. Select 'Display a list of the known drivers for this device', then 'Show all hardware of this device class'. Now you can select 'Standard-PC' in the list shown in the right window.

No reinstall is needed, although this will cause Windows to re-detect all hardware upon reboot and probably demand "re-activation" as well.

Ha! I like your explanation better, thank you.

You see, I used anandtech's, and now my computer is FUBAR.

I'm now deciding whether to reset my system.sys in the recovery console (again), this time physically removing my various pci cards, or whether I'll just move some stuff around and do a new clean install on a different drive :P

Thanks for that info-- if I go the former route, I'll definitely give it a try :)
