IRQs & SCSI

I have a Adaptec ava-2906 scsi card (set on irq 9) that has the little yellow exclamation mark next to it in device manager. I reinstalled the current version of the driver several time. I wanted to change it’s irq (irq 9 is linked to 2, so shouldn’t it not be used by the scsi card?) to see if that is the problem. I went into device manager, properties off the scsi card, resources tab to get to the irq #. It wouldn’t let me change it there.
Is there somewhere else I can bump it off 9 or setit somewhere else (11 or 15)? Thanks
