   4 **  Copyright (C) 1998-2001  Gerard Roudier <groudier@free.fr>
   5 **
   6 **  This driver also supports all the Symbios 53C8XX controller family,
   7 **  except 53C810 revisions < 16, 53C825 revisions < 16 and all
   8 **  revisions of 53C815 controllers.
   9 **
  10 **  This driver is based on the Linux port of the FreeBSD ncr driver.

  32 **  The Linux port of the FreeBSD ncr driver has been achieved in
  33 **  november 1995 by:
  34 **
  35 **          Gerard Roudier              <groudier@free.fr>
  36 **
  37 **  Being given that this driver originates from the FreeBSD version, and
  38 **  in order to keep synergy on both, any suggested enhancements and corrections
  39 **  received on Linux are automatically a potential candidate for the FreeBSD
  40 **  version.
  41 **
  42 **  The original driver has been written for 386bsd and FreeBSD by
  43 **          Wolfgang Stanglmeier        <wolf@cologne.de>
  44 **          Stefan Esser                <se@mi.Uni-Koeln.de>
