The 2090 is a bad card. You may want to save yourself some anguish and get a 2091 or other SCSI card! I think that if all you have on the card is the internal SCSI HD, termination should be set to the HD only. The 2090 should have termination packs on the card? Not 100% sure on that one, I know for sure the 2091 has them. I would get the HD model number and search on Google for some documentation. Jumper settings, etc. You will want to find out what device # it is at, and how to turn on termination.
