	TapeWare NCR-5380 Controller Driver

	This is a very simple implementation of the NCR-5380 series of
	controllers. It does not support disconnet/reconnect.

	Date		Mod	Description
	-------------	---	-----------------------------------------------
	July 10, 1991	MDB	Created driver for EV-8119
	July 12, 1991	MDB	Added support for EV-8111 on PS/2
	July 16, 1991	MDB	Corrected error in GetTransferLength
	July 16, 1991	MDB	Added phase handling functions to
				StartCommand. Also added Message-OUT
				(IDENTIFY w/o DISCONNECT) to support
				reserve unit command.

	July 24, 1991	MDB	Corrected problem in select time-out
				when executing during an interrupt
				service. Since no dispatching takes
				place at this time, the select time-
				out value was not long enough.

	August 8, 1991	MDB	Problem with configuring controller
				card. When programming interrupt and
				DMA, the controller allows the IRQ
				lines to float unless the inhibit
				line is set while programming. Once
				programmed, this bit can be reset.

	August 16, 1991	MDB	Problem with select time-out. Since
				this can't be accurately timed via
				TapeWare's internal clock system due
				to the possibility of this routine
				being called within an interrupt
				service routine, the time-out values
				can very greatly depending on the
				processor speed. So, we are going
				to make the time-out period very
				long.

	24-Sep-1991	RAC	Added support for 3.01 header files and
				Borland C++ compiler. Changed version number
				to 3.01.00.

	27-Jan-1992	MDB	Changed version number to 4.00

	5-Aug-1992	MDB	Added dispatch to time delay functions.

	16-Sep-1992	MDB	Status was not being preset to zero. When an
				unsupported command was sent to this driver,
				it would report random failure error codes.

	5-Oct-1992	MDB	Added patch in phase processing functions to
				correct for problems with DMA on some IBM
				model 80 machines.

	30-Jan-1993	RAC	Cleaned up submit and removed DEVLOAD commands

	01-Jun-1993	GMM	Update to revision to 4.20.00
