If you have the Phase5 Fastlane Z3 SCSI controller, or plan to use
one in the near future, say Y to this question. Otherwise, say N.
-config A4091_SCSI

- depends on ZORRO && SCSI && EXPERIMENTAL && BROKEN
- help
- Support for the NCR53C710 chip on the Amiga 4091 Z3 SCSI2 controller
- (1993). Very obscure -- the 4091 was part of an Amiga 4000 upgrade
- plan at the time the Amiga business was sold to DKB.

- If you have an Amiga 1200 with a Phase5 Blizzard PowerUP 603e+
- accelerator, say Y. Otherwise, say N.
+ Support for various NCR53c710-based SCSI controllers on the Amiga.
+ This includes:
+ - the builtin SCSI controller on the Amiga 4000T,
+ - the Amiga 4091 Zorro III SCSI-2 controller,
+ - the MacroSystem Development's WarpEngine Amiga SCSI-2 controller
+ (info at
+ <http://www.lysator.liu.se/amiga/ar/guide/ar310.guide?FEATURE5>),
+ - the SCSI controller on the Phase5 Blizzard PowerUP 603e+
+ accelerator card for the Amiga 1200,
+ - the SCSI controller on the GVP Turbo 040/060 accelerator.
+ Note that all of the above SCSI controllers, except for the builtin
+ SCSI controller on the Amiga 4000T, reside on the Zorro expansion
+ bus, so you also have to enable Zorro bus support if you want to use
+ them.

This will enable 10MHz FAST-SCSI transfers with your host
adapter. Some systems have problems with that speed, so it's safest
