The driver has not seen any maintainer activity or other work that
wasn't tree wide conversion or clenaups in the entire history of
the git tree.

-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.

-   Willmore for extensive 'bonnie' testing. And to Joe Mack for
