If you are just looking to connect these to your onboard 50 pin SCSI

SE" (Single Ended) jumper pins.

Thanks,

It will help avoid some termination issues in some configurations when you have an LVD capable drive and you are running it on a non-LVD capable system (single ended).


Come to think of it, now that you have asked, it really shouldn't matter if it's run without this jumped on a 75xx/76xx -95xx/96xx on the internal SCSI bus as single ended is the only mode/speed the bus will run and the drive should automatically revert to SE. Anyone having issues should try that jumper first.
