My Geforce 2 was acting a little wierd so i checked to make sure everything was looking okay in the IRQ's by a friends advise. To my surprise there were 8 devices all listed as sharing IRQ 9!! I cant figure out how to change them in win 2000. Also it doesnt show them as causing any probs though........
Anyone familiar with this problem? Know how to fix?

This is not usually a problem. This is a feature of ACPI (Advanced Configuration and Power Interface).

<A HREF="http://www.pcforrest.freeserve.co.uk/power_management.h..." target="_new">APM - also ACPI, OnNow And SIPC</A>

It is perfectly normal for several devices to share an IRQ in Win2K. And Microsoft doesn't recommend enabling an older power management interface such as APM and manually changing the IRQs unless there is no other way to troubleshoot a device conflict ... especially with ACPI-compliant hardware and drivers. The ACPI HAL is far superior to a Standard HAL.

Here is the <A HREF="http://support.microsoft.com/directory/article.asp?ID=k...;en-us;Q237556" target="_new">information</A> you'll need to disable ACPI. But, personally, I'd really consider this to be a last-ditch-effort, and not the first item on the list when troubleshooting a video card. Seriously.

What has your video card been doing that is "weird", exactly?

YO. there is a way you can adjust the irq settings, but w2k does a pretty good job of it. unless you have the ability to mess with the bios settings i would just leave it alone if it is working..i have about 7 or 8 things on irq 9 on my machine and it works fine..w2k is setup to handle this type of situation..good luck..

i am getting things like blue smears with on screen text, some ghosting, rolling lines,screen clicking and then going black and then kicking back to normal. All happens in 2D and 3D. I know this was a prob in win 98 for a friend of mine and no drivers above 7.xx would work right. The link you sent has some similar trouble shooters topics thanks. As far as the IRQ's i am also inclined to leave them alone. Thanks again
