My system stops with the ATTO host adapter installed and displays a flashing question mark:

* This is an indication that the MAC is not able to find an OS to boot from.
* Use a CD or some other source to boot from and make sure the startup disk is correctly defined in "Control Panel" "Startup disks".
* Check cabling. Make sure cables are secure. Swap out with new cable if possible.
* Check termination
