22 ** This driver has been ported to Linux from the FreeBSD NCR53C8XX driver
23 ** and is currently maintained by
25 ** Gerard Roudier <groudier@free.fr>
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
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>
36 ** And has been ported to NetBSD by
37 ** Charles M. Hannum <mycroft@gnu.ai.mit.edu>
