IRQ prob

[Hawg-dawg]

My radeon 9800 pro is shareing IRQ with USB contr . When I installed it on abit Ic7-g MOBO it had its own IRQ(16) . I think it causes FPS probs .How do I asighn seperate IRQs . I did something to jack it up like this , wonder what ? Where are IRQs 2,3,5,7..........................

I recently asked the same question: http://forums.tweaktown.com/showthre...hreadid=13968. They told me not to mess with it if it isnt directly IRQ related. What kind of FPS probs are you having? It might not be IRQs. I also read some literature on it. To change IRQs, usually people just rearrange their PCI cards. Seeing that yours is graphics card related (AGP bus), you cant do that, so you'll have to go through BIOS. Changing IRQs through the BIOS is pretty risky (so I read) and you can mess up your system if you dont do it right. Look around online for a guide, or wait for someone with more knowledge on this subject to reply. Good luck with it, : peace2: Mista K6.
