On my Gateway, I have an option to reset the system resources. This effectively re-IRQs everything. I used to have this problem when I added new cards to my Gateway P5-166 (now a 233). What about IRQs 14 and 15? They're typically used for on-board IDE, but if you have SCSI, can you disable them? I have my on-board ATI graphics card at IRQ 9, my Linksys ethernet card at IRQ 11, my Adaptec 2930 at IRQ 10, my secondary IDE controller at IRQ 15, and my add-on Promise ATA100 controller at IRQ 5. This is my Gateway. I also have plug and play set to No. I think if you dig enough through the BIOS, you should be able to find a way to free up the resources.
