Coincidentally....I encountered this exact process a few hours ago. I asked a buddy of mine who is much more knowledgeable about SCSI voodoo because I intend to go strictly ATA in my Genesis which has the same Tsunami motherboard as the 9500.
He popped open a SGI (Silicon Graphics) computer and pulled the internal SCSI ribbon out of it and gave it to me. The SGI method of dealing with SCSI termination is to permanently terminate the actual SCSI cable and not the devices on it !!! The cable has connectors to plug into the Motherboard and into the hard drive and CD=ROM drive and a black terminator permanently attached to the end of it. He assures me that I can simply plug this SCSI cable into the connector on the board and the internal bus will be properly terminated without any devices on it. I'm sure there are terminators that you can buy from somewhere that will plug into your SCSI harness.
