I hadn't but after a tip by Rens I did and my video card and my sound card shared the same IRQ!
This is a bad thing and can give many problems as stutter etc.

How to check the IRQs:
Open the Controll panel
Double-click System
Click Device Manager tab
Double-click on the computer icon, which is in the top of the list.
This will give you a complete report of all IRQs and which devices that are using them..
Its OK if a device is sharing an IRQ with a “IRQ Holder”, that's only a part of Windows PCI bus IRQ steering.

What I did to correct the problem was to move my sound card to another PCI-slot and now my video card and my sound card have there own IRQs.

Nice tip vonOben. Thanks.

Found a couple of shared IRQ's, but as you sau they are 'holders', so no drama.

On the last one though (setting 15) I have a question. I have 'Intel 82371AB/EB PCI Bus Master IDE Controller', and also 'Secondary IDE controller (dual fifo). That ok?

Hi Pips

I have the same devices on 15 as you have. The most important is to avoid having your video card and sound card on the same IRQ, especially when playing games. If you have a lot of devices it can be impossible to avoid devices sharing IRQs since there are only 16 IRQs available.

Cheers
