+ * Device driver optimized for the Symbios/LSI 53C896/53C895A/53C1010
+ * PCI-SCSI controllers.
+ *
+ * Copyright (C) 1999-2001 Gerard Roudier <groudier@free.fr>
+ *
+ * This driver also supports the following Symbios/LSI PCI-SCSI chips:
+ * 53C810A, 53C825A, 53C860, 53C875, 53C876, 53C885, 53C895,
+ * 53C810, 53C815, 53C825 and the 53C1510D is 53C8XX mode.
+ *
+ *
+ * This driver for FreeBSD-CAM is derived from the Linux sym53c8xx driver.
+ * Copyright (C) 1998-1999 Gerard Roudier
+ *
+ * The sym53c8xx driver is derived from the ncr53c8xx driver that had been
+ * a port of the FreeBSD ncr driver to Linux-1.2.13.
+ *
+ * The original ncr driver has been written for 386bsd and FreeBSD by
+ * Wolfgang Stanglmeier <wolf@cologne.de>
+ * Stefan Esser <se@mi.Uni-Koeln.de>
+ * Copyright (C) 1994 Wolfgang Stanglmeier
+ *
+ * The initialisation code, and part of the code that addresses
+ * FreeBSD-CAM services is based on the aic7xxx driver for FreeBSD-CAM
+ * written by Justin T. Gibbs.
+ *
+ * Other major contributions:
+ *
+ * NVRAM detection and reading.
