General description
-------------------

This is a replacement for the factory driver for the CLtd SCSI controller.
It was originally written for the A1000 controller with the "SCSI-DOS 2.01
upgrade" PAL.  It should work with this controller or any other compatible
version.  The included configlist program can be used to check the
controller version before installation.


Features
--------

Near-theoretical transfer rate, given the limitations of the hardware.

Does not "hog" the CPU while waiting for mechanical delays.

Handles UNIT ATTENTION status properly.

Sends a SCSI RESET initially, avoiding the need to power-cycle the drive
if a crash or hang occurs during a transfer.

Non-copying unbuffered design for best FFS performance.

Supports the "SCSI direct" command, allowing access to all SCSI device types,
and the use of various SCSI utilities.

Drive addressing is compatible with most other Amiga SCSI drivers.

Performs SCSI bus arbitration, allowing sharing of devices between computers.
WARNING: THIS DOES *NOT* BY ITSELF PROVIDE A SHARED FILE SYSTEM - BEWARE!!!

Should work correctly with most accelerators.

Supports LUNs and multiple controllers.

Does not get confused by unexpected SCSI phase sequences.

Fully enforces all buffer boundaries, even if the device misbehaves.

Does not send SCSI RESETs to abandon unsuccessful selections.


System requirements
-------------------

Amiga equipped with one or more compatible CLtd SCSI controllers.

CPU:	Written for 000/010 <=16MHz or 020/030 <=50MHz.
	Tested on 68010  at  7.16MHz.

OS:	Written for OS 1.2 through at least OS 3.1.  Tested under 1.3 & 2.04.
