| |
| 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. |
