STOP The IRQ sharing!!!

When ever I try to add my ati tv wonder to my computer, my comp goes crazy. I have an Asus cusl2 with a Geforce 2, Sblive, Linksys 10/100 card already installed in the slots. Seems like The NIC and Sblive want to share irq 9 no matter where I put the cards. How can I stop this.
 
The thing I always do is disable serial ports since I don't ever use 'em, then after that I disable USB ports if need be. This way more IRQ's will be available and windows automatically uses free ones.
 
Try what fivespeed says and if that STILL doesn't work then try taking both cards out, start Windows, then add one card, start Windows, then add the other card, start Windows.
This way Windows assigns the IRQ one card at a time instead of both at once.

What fivespeed said should do the trick though.
 
please tell me the order in which all the PCI slots are taken..

it may just be that your motherboard cannot assign a seperate IRQ to that slot. if so, then you should try enabling ACPI.

go to the control panel/system icon.. then go to device manager, and go to the system devices group.

double click on the PCI bus icon, go to the irq steering tab, and check the 'get irq table using ACPI BIOS' check box.

make sure in your BIOS in the PnP devices area (or something similar) that 'PnP OS Installed' is enabled, or true..

that SHOULD allow the devices to share IRQ's without any problem, it fixed my problem with my Hollywood + sharing with my PCI modem (cause they were on slots that shared IRQ's).
 
slot 1 -Linksys NIC
slot 3 -SBlive
slot 2,4,5 available for ATI TV card however it will assign it to the same irq as the others
However I will try all the methods mentioned above....
thanks!

 
Are you using Windows 2000 by chance?

As you can see, in Windows 2000 it's normal for devices to share IRQ 9. If your system is stable then don't sweat it.
 
In addition to the good points above, some mobos have certain PCI slots designated as Busmastering slots, so the order the cards are installed can make a difference. The mobo BIOS or manual should tell you which are masters and which aren't.
