-          If you own a Texas Instruments graphing calculator and use a
-          parallel link cable, then you might be interested in this driver.
-
-          If you enable this driver, you will be able to communicate with
-          your calculator through a set of device nodes under /dev. The
-          main advantage of this driver is that you don't have to be root
-          to use this precise link cable (depending on the permissions on
-          the device nodes, though).
-
-          To compile this driver as a module, choose M here: the
-          module will be called tipar.
-
-          If you don't know what a parallel link cable is or what a Texas
-          Instruments graphing calculator is, then you probably don't need this
-          driver.

-/* Hey EMACS -*- linux-c -*-
- *
- * tipar - low level driver for handling a parallel link cable designed
- * for Texas Instruments graphing calculators (http://lpg.ticalc.org).
- * A part of the TiLP project.
- *
- * Copyright (C) 2000-2002, Romain Lievin <roms@lpg.ticalc.org>
- * under the terms of the GNU General Public License.
- *
- * Various fixes & clean-up from the Linux Kernel Mailing List
- * (Alan Cox, Richard B. Johnson, Christoph Hellwig).
- */
-
-/* This driver should, in theory, work with any parallel port that has an
- * appropriate low-level driver; all I/O is done through the parport
- * abstraction layer.
- *
- * If this driver is built into the kernel, you can configure it using the
- * kernel command-line.  For example:
- *
- *      tipar=timeout,delay       (set timeout and delay)
- *
- * If the driver is loaded as a module, similar functionality is available
- * using module parameters.  The equivalent of the above commands would be:
- *
- *      # insmod tipar timeout=15 delay=10
- */
-
-/* COMPATIBILITY WITH OLD KERNELS
- *
- * Usually, parallel cables were bound to ports at
- * particular I/O addresses, as follows:
- *
- *      tipar0             0x378
- *      tipar1             0x278
- *      tipar2             0x3bc
- *
- *
- * This driver, by default, binds tipar devices according to parport and
- * the minor number.

  * This is the IDE probe module, as evolved from hd.c and ide.c.
  *
- * Version 1.00         move drive probing code from ide.c to ide-probe.c
- * Version 1.01         fix compilation problem for m68k
- * Version 1.02         increase WAIT_PIDENTIFY to avoid CD-ROM locking at boot
- *                       by Andrea Arcangeli
- * Version 1.03         fix for (hwif->chipset == ide_4drives)
- * Version 1.04         fixed buggy treatments of known flash memory cards
- *
- * Version 1.05         fix for (hwif->chipset == ide_pdc4030)
- *                      added ide6/7/8/9
- *                      allowed for secondary flash card to be detectable
- *                       with new flag : drive->ata_flash : 1;
- * Version 1.06         stream line request queue and prep for cascade project.
- * Version 1.07         max_sect <= 255; slower disks would get behind and
- *                      then fall over when they get to 256.    Paul G.
