IRQ Conflict

I installed an Aureal sound card and an Adaptec SCSI card and the system keeps assigning them the same IRQ number. The sound card works but the SCSI card will not. Windows will not let me change the IRQ number on either of the cards and I changed the slot that the cards were in hoping that this would solve the problem but it does not. What can I do to either get these two devices working on the same IRQ number or change the IRQ number on one of them?
 
Try looking in the BIOS settings. Depending on your board you may be able to change it in there. Also, change the slots you have the cards in as different slots will be assigned different IRQ's. You might also take a look at the SCSI card, does it offer jumpers to set the IRQ? Good Luck!
 
NicColt is absolutely right. I had that same dilemna. I have 2 PCI NICs, an MX300 and a Viking winmodem, and the MX300 would share IRQ11 with 1 NIC along with the PCI to USB controller, causing my system to randomly lockup when playing sound files. Manually assigning a free IRQ to the NIC would cause the NIC to not work, and manually assigning a free IRQ to the soundcard would cause Windows to not even load. After removing the winmodem and shuffling my NIC and MX300 around, I finally got it to work, but at the expense of removing the winmodem...its really a trial and error process. If you're patient and lucky, you'll find the right combination to make everything work.
