| 7 | depends on ARCH_ACORN && SCSI |
| 8 | select SCSI_SPI_ATTRS |
| 9 | help |
| 10 | This enables support for the Acorn SCSI card (aka30). If you have an |
| 11 | Acorn system with one of these, say Y. If unsure, say N. |
| 12 | |
| 13 | config SCSI_ACORNSCSI_TAGGED_QUEUE |
| 14 | bool "Support SCSI 2 Tagged queueing" |
| 15 | depends on SCSI_ACORNSCSI_3 |
| 16 | help |
| 17 | Say Y here to enable tagged queuing support on the Acorn SCSI card. |
| 18 | |
| 19 | This is a feature of SCSI-2 which improves performance: the host |
| 20 | adapter can send several SCSI commands to a device's queue even if |
| 21 | previous commands haven't finished yet. Some SCSI devices don't |
| 22 | implement this properly, so the safe answer is N. |
| 23 | |
| 24 | config SCSI_ACORNSCSI_SYNC |
| 25 | bool "Support SCSI 2 Synchronous Transfers" |
| 26 | depends on SCSI_ACORNSCSI_3 |
| 27 | help |
| 28 | Say Y here to enable synchronous transfer negotiation with all |
| 29 | targets on the Acorn SCSI card. |
| 30 | |
| 31 | In general, this improves performance; however some SCSI devices |
| 32 | don't implement it properly, so the safe answer is N. |

| 34 | config SCSI_ARXESCSI |
| 35 | tristate "ARXE SCSI support" |
| 36 | depends on ARCH_ACORN && SCSI |
| 37 | help |
| 38 | Around 1991, Arxe Systems Limited released a high density floppy |
| 39 | disc interface for the Acorn Archimedes range, to allow the use of |
| 40 | HD discs from the then new A5000 on earlier models. This interface |
| 41 | was either sold on its own or with an integral SCSI controller. |
| 42 | Technical details on this NCR53c94-based device are available at |
| 43 | <http://www.cryton.demon.co.uk/acornbits/scsi_arxe.html> |
| 44 | Say Y here to compile in support for the SCSI controller. |

| 47 | tristate "CumanaSCSI II support" |
| 48 | depends on ARCH_ACORN && SCSI |
| 49 | help |
| 50 | This enables support for the Cumana SCSI II card. If you have an |
| 51 | Acorn system with one of these, say Y. If unsure, say N. |

| 54 | tristate "EESOX support" |
| 55 | depends on ARCH_ACORN && SCSI |
| 56 | help |
| 57 | This enables support for the EESOX SCSI card. If you have an Acorn |
| 58 | system with one of these, say Y, otherwise say N. |

| 62 | depends on ARCH_ACORN && SCSI |
| 63 | help |
| 64 | This enables support for the Powertec SCSI card on Acorn systems. If |
| 65 | you have one of these, say Y. If unsure, say N. |
