It si supposed to support SCSI 160, but anyway the machine I have only supports 80Mb. The problem is the following: - at boot time, going to the Symbios bios, the tape is given at maximum speed, 80 Mb - once FreeBSD is started, it only supports half the speed: sa0 at sym1 bus 0 target 2 lun 0 sa0: Removable Sequential Access SCSI-2 device sa0: 40.000MB/s transfers (20.000MHz, offset 15, 16bit) Any idea on the reason why? Eventually, I had to modify /usr/src/sys/cam/scsi/scsi_sa.c to remove the leading blank from the model name in the quirk table.
