Interrupt sharing in Windows2000

[tore78]

I'm running a AK33 mobo. Via chipset KT133 chipset as everyone knows.

When I install Windows2000 on my computer a stange things happend. No matter what I do Windows2000 assigns all my peferitials cards, like onboard sound, SCSI-card (Tekram DC390F)and VideoCard(ASUS 7110), to use very same IRQ.

I believe that couses an conflict between onboard sound and my Video card. My sound scratches when I bouth listen to sound and running som small video appl. like a winamp visualsion.

I'm using the newest drivers from viahardware.com but it doesn't solve the problem.

Can someone help me with the problem and I connot be alone with this. Can one get in contact with Aopen and discus this with them.

try switching pci slots

dont use the first pci slot cuz it is assigned to use the same interrupt as your agp slot.

It's win2k using ACPI to take over what bios usually does. It stacks up all the cards onto on irq, mine does the same thing and everything goes on IRQ 9

you can disable it by going into device manager and switching your computer type to Standard PC instead of ACPI PC. It'll automatically reconfigure your drivers and such after a reboot.

When you switch to standard PC, will the pc still share irqs?

No, each item will be assigned different IRQ's.

I changed my computer to a Standard Computer and my IRQs are now spread over my devices. A big improvement !

But saidly it didn't solve the scratching sound from my onboard sound when I run some video appl at the same time. The problem is gone in WindowsMe but now Win2k.

Is there someway one could take direct contact to Aopen and solve this ?

Hey tore78, when you switched from ACPI to Standard Computer, did you have any shutdown problems?
