+ * Device driver for the SYMBIOS/LSILOGIC 53C8XX and 53C1010 family 
+ * of PCI-SCSI IO processors.

+ * 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>
