3 | FlashPoint.c -- FlashPoint SCCB Manager for Linux | |
4 | ||
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. | |
