		UPDATE NEWS: version 1.33 - 26 Aug 98

		Interrupt management in this driver has become, over
		time, increasingly odd and difficult to explain - this
		has been mostly due to my own mental inadequacies. In
		recent kernels, it has failed to function at all when
		compiled for SMP. I've fixed that problem, and after
		taking a fresh look at interrupts in general, greatly
		reduced the number of places where they're fiddled
		with. Done some heavy testing and it looks very good.
		The driver now makes use of the __initfunc() and
		__initdata macros to save about 4k of kernel memory.
		Once again, the same code works for both 2.0.xx and
		2.1.xx kernels.

		UPDATE NEWS: version 1.32 - 28 Mar 98

		Removed the check for legal IN2000 hardware versions:
		It appears that the driver works fine with serial
		EPROMs (the 8-pin chip that defines hardware rev) as
		old as 2.1, so we'll assume that all cards are OK.

		UPDATE NEWS: version 1.31 - 6 Jul 97

		Fixed a bug that caused incorrect SCSI status bytes to be
		returned from commands sent to LUNs greater than 0. This
		means that CDROM changers work now! Fixed a bug in the
		handling of command-line arguments when loaded as a module.
		Also put all the header data in in2000.h where it belongs.
		There are no longer any differences between this driver in
		the 2.1.xx source tree and the 2.0.xx tree, as of 2.0.31
		and 2.1.45 (or is it .46?) - this makes things much easier
		for me...

		UPDATE NEWS: version 1.30 - 14 Oct 96

		Fixed a bug in the code that sets the transfer direction
		bit (DESTID_DPD in the WD_DESTINATION_ID register). There
		are quite a few SCSI commands that do a write-to-device;
		now we deal with all of them correctly. Thanks to Joerg
		Dorchain for catching this one.

		UPDATE NEWS: version 1.29 - 24 Sep 96

		The memory-mapped hardware on the card is now accessed via
		the 'readb()' and 'readl()' macros - required by the new
		memory management scheme in the 2.1.x kernel series.
		As suggested by Andries Brouwer, 'bios_param()' no longer
		forces an artificial 1023 track limit on drives. Also
		removed some kludge-code left over from struggles with
		older (buggy) compilers.

		UPDATE NEWS: version 1.28 - 07 May 96

		Tightened up the "interrupts enabled/disabled" discipline
		in 'in2000_queuecommand()' and maybe 1 or 2 other places.
		I _think_ it may have been a little too lax, causing an
		occasional crash during full moon. A fully functional
		/proc interface is now in place - if you want to play
		with it, start by doing 'cat /proc/scsi/in2000/0'. You
		can also use it to change a few run-time parameters on
		the fly, but it's mostly for debugging. The curious
		should take a good look at 'in2000_proc_info()' in the
		in2000.c file to get an understanding of what it's all
		about; I figure that people who are really into it will
		want to add features suited to their own needs...
		Also, sync is now DISABLED by default.

		UPDATE NEWS: version 1.27 - 10 Apr 96

		Fixed a well-hidden bug in the adaptive-disconnect code
		that would show up every now and then during extreme
		heavy loads involving 2 or more simultaneously active
		devices. Thanks to Joe Mack for keeping my nose to the
		grindstone on this one.

		UPDATE NEWS: version 1.26 - 07 Mar 96

		1.25 had a nasty bug that bit people with swap partitions
		and tape drives. Also, in my attempt to guess my way
		through Intel assembly language, I made an error in the
		inline code for IO writes. Made a few other changes and
		repairs - this version (fingers crossed) should work well.

		UPDATE NEWS: version 1.25 - 05 Mar 96

		Kernel 1.3.70 interrupt mods added; old kernels still OK.
		Big help from Bill Earnest and David Willmore on speed
		testing and optimizing: I think there's a real improvement
		in this area.
		New! User-friendly command-line interface for LILO and
		module loading - the old method is gone, so you'll need
		to read the comments for 'setup_strings' near the top
		of in2000.c. For people with CDROM's or other devices
		that have a tough time with sync negotiation, you can
		now selectively disable sync on individual devices -
		search for the 'nosync' keyword in the command-line
		comments. Some of you disable the BIOS on the card, which
		caused the auto-detect function to fail; there is now a
		command-line option to force detection of a ROM-less card.

		UPDATE NEWS: version 1.24a - 24 Feb 96

		There was a bug in the synchronous transfer code. Only
		a few people downloaded before I caught it - could have
		been worse.

		UPDATE NEWS: version 1.24 - 23 Feb 96

		Lots of good changes. Advice from Bill Earnest resulted
		in much better detection of cards, more efficient usage
		of the fifo, and (hopefully) faster data transfers. The
		jury is still out on speed - I hope it's improved some.
		One nifty new feature is a cool way of doing disconnect/
		reselect. The driver defaults to what I'm calling
		'adaptive disconnect' - meaning that each command is
		evaluated individually as to whether or not it should be
		run with the option to disconnect/reselect (if the device
		chooses), or as a "SCSI-bus-hog". When several devices
		are operating simultaneously, disconnects are usually an
		advantage. In a single device system, or if only 1 device
		is being accessed, transfers usually go faster if disconnects
		are not allowed.



		The default arguments (you get these when you don't give an 'in2000'
		command-line argument, or you give a blank argument) will cause
		the driver to do adaptive disconnect, synchronous transfers, and a
		minimum of debug messages. If you want to fool with the options,
		search for 'setup_strings' near the top of the in2000.c file and
		check the 'hostdata->args' section in in2000.h - but be warned! Not
		everything is working yet (some things will never work, probably).
		I believe that disabling disconnects (DIS_NEVER) will allow you
		to choose a LEVEL2 value higher than 'L2_BASIC', but I haven't
		spent a lot of time testing this. You might try 'ENABLE_CLUSTERING'
		to see what happens: my tests showed little difference either way.
		There's also a define called 'DEFAULT_SX_PER'; this sets the data
		transfer speed for the asynchronous mode. I've put it at 500 ns
		despite the fact that the card could handle settings of 376 or
		252, because higher speeds may be a problem with poor quality
		cables or improper termination; 500 ns is a compromise. You can
		choose your own default through the command-line with the
		'period' keyword.

		In later ROMs (starting with 01.3 in April 1994) sw1-8 controls

		MSDOS 5.0 (ignored by Linux):
		off = 2 drives maximum

		I should mention that Drew Eckhardt's 'Generic NCR5380' sources
		were my main inspiration, with lots of reference to the IN2000
		driver currently distributed in the kernel source. I also owe
		much to a driver written by Hamish Macdonald for Linux-m68k(!).
		And to Eric Wright for being an ALPHA guinea pig. And to Bill
		Earnest for 2 tons of great input and information. And to David
		Willmore for extensive 'bonnie' testing. And to Joe Mack for
		continual testing and feedback.
