| 2787 | The OnStream SC-x0 SCSI tapes do not support the |
| 2788 | standard SCSI SASD command set and therefore need |
| 2789 | their own driver "osst". Note that the IDE, USB (and |
| 2790 | maybe ParPort) versions may be driven via ide-scsi or |
| 2791 | usb-storage SCSI emulation and this osst device and |
| 2792 | driver as well. The ADR-x0 drives are QIC-157 |
| 2793 | compliant and don't need osst. |
