I have a HP Proliant ML370 G4 server running Windows Server 2003 SP1. I am trying to attach a Quantum ATL Superloader tape backup unit to the scsi ports on the back of the server. When I try to boot after I connect the device, I receive error "1776 - Slot 1 - SCSI Bus Termination error - Internal and external drives cannot both be attached to the same scsi port. Controller is disabled." If I disconnect the Quantum unit, my server will boot as normal. I've tried updating the firmware for the controller, and still get the same error.
