2 * sym53c500_cs.c Bob Tracy (rct@frus.com)
4 * A rewrite of the pcmcia-cs add-on driver for newer (circa 1997)
5 * New Media Bus Toaster PCMCIA SCSI cards using the Symbios Logic
6 * 53c500 controller: intended for use with 2.6 and later kernels.
7 * The pcmcia-cs add-on version of this driver is not supported
8 * beyond 2.4. It consisted of three files with history/copyright
9 * information as follows:
12 * Bob Tracy (rct@frus.com)
13 * Original by Tom Corner (tcorner@via.at).
14 * Adapted from NCR53c406a.h which is Copyrighted (C) 1994
15 * Normunds Saumanis (normunds@rx.tech.swh.lv)
18 * Bob Tracy (rct@frus.com)
19 * Original driver by Tom Corner (tcorner@via.at) was adapted
20 * from NCR53c406a.c which is Copyrighted (C) 1994, 1995, 1996
21 * Normunds Saumanis (normunds@fi.ibm.com)
24 * Bob Tracy (rct@frus.com)
25 * Original by Tom Corner (tcorner@via.at) was adapted from a
26 * driver for the Qlogic SCSI card written by
27 * David Hinds (dhinds@allegro.stanford.edu).
