-** High Performance device driver for the Symbios 53C896 controller.
-**
-** Copyright (C) 1998-2001 Gerard Roudier <groudier@free.fr>
-**
-** This driver also supports all the Symbios 53C8XX controller family,
-** except 53C810 revisions < 16, 53C825 revisions < 16 and all
-** revisions of 53C815 controllers.
-**
-** This driver is based on the Linux port of the FreeBSD ncr driver.

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

-** NVRAM detection and reading.
