Support for various NCR53c710-based SCSI controllers on Zorro

expansion boards for the Amiga.
|

This includes:

- the Amiga 4091 Zorro III SCSI-2 controller,
|
||||
- the MacroSystem Development's WarpEngine Amiga SCSI-2 controller

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.
