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. |
