    *My* brand-less 810 SCSI controller card, which according to
    /proc/scsi/ncr53c8xx/0 is a:

      Chip NCR53C810, device id 0x1, revision id 0x2

    does *not* do any sort of auto termination (I don't believe that any
    810 *does*, but don't quote me). I have to *remove* one (or was it
    two?) little SIL (Single In-Line) resistor packs to *disable*
    termination. This seams to imply that I only have *passive*
    termination at the controller. My (Relisys) Scanner has fixed passive
    termination behind it's nonstandard 25 pin SCSI socket.

    May I recommend the "SCSI FAQ" and the no longer maintained "Linux
    SCSI HOWTO" as two valuable sources of information about SCSI in
    practice.
