Thanks, Robert. I have now installed the PCI probe, and it reports four devices using IRQ 11. I've placed them below. How would I change this? I don't see any way to change IRQ used by ServeRaid or Adaptec using either command line parameters, or the configuration programs for the SCSI adpaters in the BIOS.
