**  This driver has been ported to Linux from the FreeBSD NCR53C8XX driver
23
**  and is currently maintained by
24
**
25
**          Gerard Roudier              <groudier@club-internet.fr>
26
**
27
**  Being given that this driver originates from the FreeBSD version, and
28
**  in order to keep synergy on both, any suggested enhancements and corrections
29
**  received on Linux are automatically a potential candidate for the FreeBSD
30
**  version.
31
**
32
**  The original driver has been written for 386bsd and FreeBSD by
33
**          Wolfgang Stanglmeier        <wolf@cologne.de>
34
**          Stefan Esser                <se@mi.Uni-Koeln.de>
35
**
36
**  And has been ported to NetBSD by
37
**          Charles M. Hannum           <mycroft@gnu.ai.mit.edu>
