          Fast means that the timing on the bus is somewhat different, so
          that on a narrow (8 bit) bus 10 Mbytes/sec are possible instead
          of 5 Mbytes/sec for 'slow' SCSI. More on this later.

        This is exactly where the 'rogue' devices come into view. Rogues are
        devices that are recognized by the FreeBSD kernel as behaving slightly
        (...) non-standard. Rogue devices are reported by the kernel when
        booting. An example for two of my cartridge tape units:

        If you are the first
        to connect your bogus Mumbletech SCSI cdrom you might be the one
        that has to define which workaround is needed.
