This enables support for the Acorn SCSI card (aka30). If you have an Acorn system with one of these, say Y. If unsure, say N.
Say Y here to enable tagged queuing support on the Acorn SCSI card. This is a feature of SCSI-2 which improves performance: the host adapter can send several SCSI commands to a device's queue even if previous commands haven't finished yet. Some SCSI devices don't implement this properly, so the safe answer is N.
Say Y here to enable synchronous transfer negotiation with all targets on the Acorn SCSI card. In general, this improves performance; however some SCSI devices don't implement it properly, so the safe answer is N.
Around 1991, Arxe Systems Limited released a high density floppy disc interface for the Acorn Archimedes range, to allow the use of HD discs from the then new A5000 on earlier models. This interface was either sold on its own or with an integral SCSI controller. Technical details on this NCR53c94-based device are available at <http://www.cryton.demon.co.uk/acornbits/scsi_arxe.html> Say Y here to compile in support for the SCSI controller.
This enables support for the Cumana SCSI II card. If you have an Acorn system with one of these, say Y. If unsure, say N.
This enables support for the EESOX SCSI card. If you have an Acorn system with one of these, say Y, otherwise say N.
This enables support for the Powertec SCSI card on Acorn systems. If you have one of these, say Y. If unsure, say N.
This enables support for the Cumana SCSI I card. If you have an Acorn system with one of these, say Y. If unsure, say N.
This enables support for the Oak SCSI card. If you have an Acorn system with one of these, say Y. If unsure, say N.
