XP IRQ assignments?

[Mike W.]

Hey y'all,

I have upgraded my comp from Win98SE to WindowsXP Pro.

I upgraded to WinXP pro and OfficeXP pro. It all went amazingly smooth
except for a nagging sound issue.

I think that I have narrowed it down to an IRQ issue. For some reason, my
AGP video card, network card, ACPI, USB Host, Modem and sound cards are ALL
on IRQ 9! And there is nothing on IRQ 2, 3, 5, 10 or 11. I tried using the
BIOS to force two PCI slots (sound and network) to IRQ 10 and 11, but
Windows still shows everything on IRQ 9. There was a slight improvement in
the sound, but I have no idea why.

All drivers were updated to the latest that I could find at the
manufacturer's websites.

The motherboard is an ASUS A7M266 with the latest BIOS flash.
2 ea. WD 40GB 7200rpm hard drives.
Iomega Zip100 internal.
LGE CD/RW/DVD combo drive
Soundcard - SoundBlasterLive Platinum 5.1
Network card - Aopen card.
Video card - ATI 9100 128MB.

Any ideas?

TIA,

Mike W.

In BIOS, for option "PNP OS " select "no".
and do "Reset configuration data" if there is such option.

Thanks, I'll try that when I get home and also, I'll try
swapping cards around.

However, I found this KB article that says that everything
is on IRQ 9 by design because 'load balancing' of hardware
would be too difficult for WinXP and there is no provision
for manual settings without losing other functionality
(ACPI). Thanks, MS!

Then I found this article which says that I can change
resources from the device manager. We'll see. . . lol.

Any ideas would be gratefully welcomed!
