3 FlashPoint.c -- FlashPoint SCCB Manager for Linux
5 This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint
6 Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for
7 Linux compatibility. It was provided by BusLogic in the form of 16 separate
8 source files, which would have unnecessarily cluttered the scsi directory, so
9 the individual files have been combined into this single file.
