-** 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>

-** The Linux port of the FreeBSD ncr driver has been achieved in

-** Gerard Roudier <groudier@free.fr>

-** Being given that this driver originates from the FreeBSD version, and

-** 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>
