+ FlashPoint.c -- FlashPoint SCCB Manager for Linux
+
+ This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint
+ Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for
+ Linux compatibility. It was provided by BusLogic in the form of 16 separate
+ source files, which would have unnecessarily cluttered the scsi directory, so
+ the individual files have been combined into this single file.
+
+ Copyright 1995-1996 by Mylex Corporation. All Rights Reserved
